Can #HCC extend beyond the margin we see on grayscale ultrasound?
New @radiology_rsna study explores “perfusion beyond margin” (PBM), #CEUS feature that may peak into tumor aggressiveness & prognosis.

And the biology went even deeper.
RNA sequencing showed PBM-associated changes involving:
- Angiogenesis
- Epithelial-mesenchymal transition
- An immunosuppressive tumor microenvironment
This provides a possible biologic explanation for what is being seen on CEUS.

8/8 Take-home:
The visible tumor margin may not tell the whole story. "Perfusion beyond margin" on CEUS may identify HCCs with vascular extension beyond their grayscale more invasive phenotype.

Can non-contrast abbreviated MRI (NC-AMRI) be used for post #TACE surveillance of #HCC? New in @radiology_rsna: performance of NC-AMRI using #LIRADS ancillary features for post-TACE treatment response assessment.

The authors conclude NC-AMRI demonstrates moderate diagnostic performance for post-TACE treatment monitoring but remains inferior to full-sequence liver MRI.
Its potential role may lie in selected surveillance settings rather than routine replacement of standard imaging.
