COPD severity alone does not explain cardiac changes. In the MESA COPD Study, emphysema subtypes from CT were tied to specific hemodynamic profiles on MRI, pointing toward more precise targets for therapy. More from @uclaradiology.bsky.social:

CT Emphysema Subtypes and Cardiac Hemodynamics Estimated on MRI

In this case-control study of predominantly mild-moderate COPD, greater ePAP was specific to the combined bronchitic-apical emphysema subtype whereas the diffuse emphysema subtype and COPD severity…

New research from @uclaradiology.bsky.social & colleagues introduces a Neural CRF model for prostate MRI segmentation. By using deep image features, it improves accuracy in both transition & peripheral zones, delivering consistent results across slices. pubmed.ncbi.nlm.nih.gov/40977953/

A Neural Conditional Random Field Model Using Deep Features and Learnable Functions for End-to-End MRI Prostate Zonal Segmentation - PubMed

The automatic segmentation of prostate MRI often produces inconsistent performance because certain image slices are more difficult to segment than others. In this paper, we show that consistency can…
