Cardiac Amyloidosis Through the Lens of Cardiac MRI by Diego Artemio Valadez-Villegas, MD; et al. (Instituto Nacional de Cardiología Ignacio Chávez, Ciudad de México). Cardiac magnetic resonance (CMR) plays a central role in evaluation of heart failure by clarifying both etiology and prognosis. One of its most important applications is the assessment of cardiac amyloidosis (CA), a progressive and underdiagnosed disease caused by the accumulation of amyloid fibrils in the extracellular space of the myocardium, altering contractility, impairing relaxation, and causing restrictive physiology associated with high morbidity and mortality. CA is most commonly due to either light-chain (AL) amyloidosis, derived from clonal plasma cell dyscrasia and associated with poor outcomes, or transthyretin (ATTR) amyloidosis, related to misfolded transthyretin protein synthesized in the liver. Until recently, diagnosis relied on biopsy, but this approach is invasive, less sensitive in ATTR, and limited in early disease. CMR has therefore emerged as a noninvasive, reproducible, whole-heart technique capable of characterizing myocardial composition and distinguishing CA from other cardiomyopathies.

#CardioSky #MRI #AdultCHD #WhyCMR
@banksgaia.bsky.social
Survival of patients with congenital heart disease (CHD) has dramatically improved over the last 30 years. Over 97% of patients now reach adulthood, as a result, the adult CHD population has outgrown the pediatric population. However, despite improved survival, CHD patients cannot be considered cured. Increased life expectancy exposes them to potential complications such as arrhythmias, stroke, heart failure, valvular heart lesions, and pulmonary arterial hypertension. Due to their high risk of complications, patients with CHD need life-long specialized follow-up. Imaging plays a central role in diagnosis and surveillance, particularly for valvular lesions, shunt quantification and assessment of cardiac volumes, and function. While transthoracic echocardiography (TTE) remains the first-line modality, it has several limitations in CHD, particularly in the assessment of right-heart lesions, which are frequently encountered in the CHD population. Cardiac magnetic resonance (CMR) overcomes these limitations and is considered the gold standard for non-invasive evaluation of ventricular volumes, myocardial structure, and flow evaluation. As the number of adult CHD patients and consequently the demand for congenital CMR is steadily increasing, rapid access to CMR has become increasingly challenging due to long waiting times. To address this issue and expand the number of examinations performed per week, our center introduced a “short CMR” strategy in 2024. In this approach, selected patients undergo an accelerated protocol tailored to the clinical indication and the need for contrast administration.

@banksgaia.bsky.social
Artificial intelligence (AI) is emerging as a powerful ally in cardiac MRI, addressing many of the challenges that previously limited its efficiency and accessibility. By automating and optimizing steps from protocol planning and image acquisition to reconstruction, analysis, and integration with clinical data, AI can make cardiac MRI faster, more consistent, and more widely available. Far from replacing clinicians, AI supports them by reducing repetitive tasks, improving reproducibility, and enabling the extraction of advanced diagnostic and prognostic information. An important aspect of this evolution is the integration of cardiac MRI into a multimodality framework where it is combined with other imaging techniques such as echocardiography or CT, and with clinical, biological, and electrophysiological data. This approach paves the way for advanced concepts like the digital twin – a virtual model of the patient’s heart that can guide diagnosis and therapy planning, further enhancing precision and personalization in cardiovascular care. The authors explore how AI is transforming their cardiac MRI practice in four main domains: 1. Planning and acquisition: including automated plane prescription and parameter optimization 2. Image reconstruction: accelerating acquisitions and improving image quality 3. Image analysis and post-processing: enabling rapid and consistent quantification 4. Development of diagnostic and prognostic tools: integrating imaging with multisource and multimodal patient data

#CardioSky #CMR #WhyCMR
@banksgaia.bsky.social
To address the challenges of prolonged scan times and reliance on patient breath-holding, a range of free-breathing CMR techniques have emerged over the past decade. These include respiratory navigator gating, self-gating, motion correction, compressed sensing, and AI-assisted sequence optimization. While impactful, most of these approaches were limited to specific sequences and did not systematically transform the overall CMR workflow. In this work, the authors introduce a fully integrated free-breathing CMR protocol that enables intelligent, rapid examinations without the need for breath-holding. Compressed Sensing (CS) and motion correction (MOCO) are core techniques implemented in the full free-breathing CMR protocol. Conceptually, CS leverages the inherent sparsity of CMR data to enable accurate image reconstruction from undersampled k-space, thereby substantially reducing acquisition time without compromising diagnostic fidelity. Motion correction utilizes advanced retrospective algorithms to compensate for respiratory and cardiac motion, effectively reducing motion-related artifacts and maintaining image quality. The core innovation lies in the deep integration of these two methodologies across several critical CMR sequences, leading to a qualitative leap in acquisition efficiency and diagnostic robustness. Full free-breathing CMR examinations are performed on a 3T MAGNETOM Vida using an 18-channel body coil. Free-breathing CMR is not only a technological innovation, but also a milestone in making advanced cardiovascular imaging more equitable and patient-centered. By eliminating reliance on breath-holding, this approach delivers faster, smarter, and more widely accessible diagnostic services.

Photon-counting CT (PCCT) represents a major step toward bridging the historical gap between cardiac CT and CMR. Its ability to provide high-resolution anatomical imaging, quantitative spectral data, and myocardial tissue characterization within a single, time-efficient acquisition brings cardiac CT closer to the comprehensive diagnostic capability traditionally reserved for CMR. However, these modalities should not be seen as competing but as highly complementary. CMR remains the reference standard for advanced tissue characterization, myocardial fibrosis assessment, and complex flow quantification, while PCCT offers unparalleled spatial resolution, reduced acquisition times, and simultaneous evaluation of coronary arteries, myocardium, and valves. Together, PCCT and CMR form a synergistic imaging approach, combining structural and functional insights to refine diagnosis, guide management, and ultimately improve patient care in cardiovascular disease.

Unlocking the Heart’s #Microstructure: Cardiac #Diffusion #MRI with Ultra-Strong Gradients by Maryam Afzali, PhD; et al. (@universityofleeds.bsky.social).

@deekayjay.bsky.social
#dMRI #RadSky #CardioSky #MagnetomWorld
Diffusion MRI of the human heart provides unique insight into myocardial microstructure but has been hampered by cardiac and respiratory motion, short T2 of the heart muscle, and limited gradient strength. Recent advances in ultra-strong gradient technology not only help to overcome these technical challenges but also allow higher diffusion weighting (i.e., b-values) with clinically compatible echo times. The authors demonstrate how this enabled in vivo diffusion kurtosis imaging (DKI) and q-space trajectory imaging (QTI) in the beating human heart, therefore moving beyond the Gaussian assumptions of diffusion tensor imaging (DTI). These advances may pave the way for more sensitive biomarkers of pathological changes of the myocardium and bring microstructural imaging closer to clinical application. Key points • Ultra-strong gradients (300 mT/m) make cardiac diffusion MRI feasible at higher b-values. • In vivo cardiac diffusion kurtosis imaging and q-space trajectory imaging (QTI) were demonstrated with clinically compatible echo times. • Kurtosis and QTI metrics reveal non-Gaussian diffusion, offering access to new imaging biomarkers of myocardial microstructure. • Translation to clinical systems is within reach with new 200 mT/m gradient scanners.

Diagnostic and Monitoring #MRI Protocols for #MultipleSclerosis, based on the MAGNIMS Consensus Recommendations & the McDonald Criteria
by Prof. Manuela Vaněčková (General University Hospital in Prague, Czech Republic).

#NeuroSky #MS #RadSky
In multiple sclerosis, care relies on MRI for diagnosis and longitudinal management. Standardized, cross-institutional MRI protocols maximize clinical utility by aligning with contemporary criteria. They enable early, accurate diagnosis and capture prognostic markers, flagging subclinical activity that may signal therapeutic ineffectiveness or safety concerns, and support equitable access to high-quality, innovative treatment. General University Hospital in Prague presents optimized therapeutic MS imaging protocols for 3T systems from Siemens Healthineers. The suite of protocols — diagnostic, monitoring, and safety — covers the brain, spinal cord, and optic nerves to provide a comprehensive assessment of central nervous system disease activity, including dissemination in space and time, negative prognostic markers, and treatment-relevant activity. For brain MRI, 3D FLAIR, high-resolution 3D MPRAGE, 3D DIR, 3D EPI, and 2D T2WI and DWI delineate lesions in white and gray matter. Contrast-enhanced imaging is performed immediately following gadolinium administration to highlight new or active lesions. Spinal cord evaluation employs sagittal T2 STIR — in line with guidance from the Magnetic Resonance in MS (MAGNIMS) network — and proton density sequences, followed by post-contrast T1 to detect inflammation and structural damage. Optic nerve assessment includes coronal and transverse T2WI with fat suppression (FS) and, after contrast administration, T1WI with FS to visualize inflammation and demyelination associated with optic neuritis. These harmonized protocols provide a reliable framework to detect, localize, and monitor MS lesions across the central nervous system in accordance with the 2021 and 2024 MAGNIMS international consensus recommendations and the diagnostic McDonald criteria.

Optimization of Petrous Internal Carotid Artery Imaging in #7T Ultra-High-Field TOF-MRA by Hui Liu, Ph.D. (Siemens Healthineers, Zhengzhou, China).
marketing.webassets.siemens-healthineers.com/97960ef4f167...

#MRI #NeuroSky #MRA #VesselImaging #UHF #UltraHighField
To date, 7T TOF-MRA has shown value in the evaluation of cerebrovascular malformations, atherosclerosis, and neurodegenerative diseases. However, it also faces challenges such as susceptibility artifacts at the air-bone interface of the sella turcica region, and physiological motion (e.g., vascular pulsation), which lead to suboptimal imaging of the petrous segment of the internal carotid artery (ICA). This paper aims to optimize imaging of the petrous ICA through optimized acquisition parameters. The petrous segment of the ICA is located in the parasellar region, where the large susceptibility difference between air and bone leads to susceptibility artifacts. These artifacts affect the homogeneity of both the B0 and B1 fields, which can result in asymmetry of TOF signals between the two sides. Even B0 shimming and volume-specific parallel-transmit (pTX) B1 shimming could not fully resolve the signal loss at the ICA. The optimization strategy was revised by altering the flow compensation scheme and increasing the acquisition bandwidth, therefore shortening the echo time (TE) and reducing the influence of T2* effects. Furthermore, changing the phase-encoding direction redirected pulsation artifacts away from critical vascular structures. Together, these approaches minimized the impact of susceptibility and pulsation artifacts in this region and led to a better display of the ICA on the TOF-MRA. The figures show a 77-year-old male with atherosclerosis. Visual inspection of the original TOF-MRA images revealed the following findings: 1. Shorter TE values exhibit superior efficacy in suppressing vascular pulsation artifacts. 2. Reduced TE improved homogeneity of the blood flow signal. 3. Under conditions of pronounced pulsation artifacts, P>>A (posterior-to-anterior) phase-encoding orientation effectively prevents cross-vessel interference induced by pulsation-related artifacts.

#RadSky #DeepLearning
Magnetic resonance imaging (MRI) plays a vital role in medical imaging, yet both healthcare in general and imaging in particular have a considerable environmental impact. MRI systems are highly energy-intensive, posing challenges for healthcare sustainability and environmental preservation. One approach to reducing MRI’s energy footprint is the use of artificial intelligence – specifically, deep learning. While deep learning applications can optimize multiple aspects of MRI operations, their ability to accelerate imaging protocols is especially relevant to sustainability. With advanced denoising techniques, deep learning maintains diagnostic image quality while significantly shortening the time required for each scan. Since faster scans use less energy, deep learning has the potential to minimize greenhouse gas emissions from MRI systems.

#RadSky #NeuroSky #DeepResolve #LowFieldMRI #Claustrophobia
This article addresses claustrophobia in #MRI patients and presents strategies to improve the overall patient experience. With its ultra-wide 80 cm bore, the 0.55T MAGNETOM Free.Max scanner is designed to create a less confining environment and enhance comfort. Its compact design and shorter magnet length allow for more flexible patient positioning. Additional measures such as using Contour coils, music during the scan, and cushions for positioning can further increase comfort. The MAGNETOM Free.Max Head/Neck coil has a 12-channel design with 12 integrated pre-amplifiers with three rungs of 4 elements. The coil is tilted to 9 degrees to give patients the feeling of lying on a pillow. The upper part, with 6 elements, can be easily removed. The lower part, also with 6 elements, is usable without the upper part for highly claustrophobic patients. Even with the upper part removed, the AutoAlign option still works. Deep learning-based image reconstruction with Deep Resolve Boost helps denoise the image and achieve good quality. Protocol adjustments, such as selecting prescan normalize, increasing the FOV, and changing the iPAT factor and average, are recommended to increase SNR when scanning without the upper part of the Head/Neck coil.

Advances in Ultra-High-Gradient MRI: High-Resolution Imaging for Accurate Diagnosis of Pancreatic Cystic Lesions by Liang Zhu, M.D.; et al. (Peking Union Medical College Hospital, Beijing, China). Pancreatic cystic lesions (PCLs) are increasingly detected in clinical practice, largely due to the widespread use of computed tomography (CT) and magnetic resonance imaging (MRI). These lesions encompass a broad spectrum of diseases with similar imaging features, ranging from non-neoplastic cysts and benign tumors to premalignant and frankly malignant neoplasms. Accurate diagnosis is therefore challenging. Benign lesions may be misinterpreted as malignancies, leading to overtreatment, while early-stage cancer may go undetected, delaying appropriate treatment. MRI offers distinct advantages for the evaluation of PCLs, including noninvasiveness, absence of ionizing radiation, superior soft-tissue contrast, and multiparametric imaging capabilities. Moreover, high-resolution MRI enabled by an ultra-high-gradient system and deep-learning reconstruction delineates subtle internal structures of PCLs and provides critical diagnostic clues. 👏 Shoutout to the co-authors: Bowen Wu, Yitong Lu (Department of Radiology, Peking Union Medical College Hospital, Beijing, China) Yueluan Jiang, Xiaoye Wang (Siemens Healthineers Ltd., Beijing, China)

Unlocking the Potential of ASL at 7T #MRI: Overcoming Challenges and Advancing Neuroscience Applications
by Danny JJ Wang (@keck.usc.edu), @jianxun-qu.bsky.social (Siemens Healthineers), et al www.magnetomworld.siemens-healthineers.com/clinical-cor...
#NeuroSky #UltraHighField @mritobi.bsky.social
Among the various functional imaging techniques, arterial spin labeling (#ASL) has emerged as a powerful tool, not only in neuroscience and cognitive research but also in clinical practice. By using water as an endogenous tracer, ASL delivers quantitative perfusion information with high spatial specificity. Over the years, ASL has demonstrated its clinical value in diagnosing and monitoring a range of neurological conditions, from stroke and brain tumors to neurodegenerative disease, and has been extensively applied at 3T and 1.5T field strengths. The advent of ultra-high-field (UHF) 7T MRI has opened new opportunities for ASL while also presenting significant technical challenges. Increased magnetic field strength accentuates B0 and RF field inhomogeneities, increases SAR, and markedly reduces transverse relaxation time (T2). These challenges, less pronounced at 3T or lower fields, demand systematic innovations and modifications to the ASL sequence to ensure robust and reliable performance at 7T. The figure shows a 45-year-old woman with pathologically confirmed oligodendroglioma. A mass with predominantly mild heterogeneous hyperintensity on T2-weighted imaging was observed in the right frontal lobe, extending into the knee of the corpus callosum, with small areas of hypointensity. Susceptibility-weighted imaging (SWI) sequences revealed signs of bleeding or calcification within the mass, and significant enhancement was noted. ASL sequences demonstrated hyperperfusion in most regions of the lesion.

Conventional high-field MRI scanners make it challenging to examine body regions containing metallic implants. The large difference in magnetic susceptibility between metal and the surrounding tissue causes significant local magnetic field distortion, leading to the familiar image artifacts around implants. Even with advanced techniques such as WARP and SEMAC, image quality on conventional 1.5T and 3T MRI systems remains limited, making accurate diagnosis difficult. At a lower field strength of 0.55T, the systems of the MAGNETOM Free. Platform have the advantage of producing significantly fewer susceptibility artifacts than high-field systems. With far fewer distortions and artifacts near implants, these lower-field scanners enable better visualization of pathologies, despite the lower resolution and signal-to-noise ratio. As in high-field imaging, these examinations use turbo spin echo (TSE) sequences with optimized acquisition parameters that are activated via the WARP option. Increased excitation and readout bandwidths are crucial here, especially in combination with STIR technology as a robust alternative to conventional spectral fat saturation for fat suppression. In addition to established advanced acceleration techniques (parallel imaging and Simultaneous Multi-Slice acquisition), deep-learning-based image reconstruction methods offer enormous potential also at lower field strengths. Enabling high-quality diagnostic MR images in very acceptable acquisition times on 0.55T systems.
