Synopsis

Keywords: Hepatobiliary, Tumor

Motivation: The study seeks to validate an abbreviated MRI protocol for HCC post-treatment surveillance.

Goal(s): To determine whether an abbreviated MRI protocol is as effective as full protocol MRI for HCC surveillance post-MWA.

Approach: A retrospective cohort study comparing abbreviated MRI to full protocol MRI in detecting HCC recurrence after microwave ablation.

Results: The abbreviated MRI achieved an acceptable sensitivity, specificity, and negative predictive value, specificity in detecting local HCC recurrences post-MWA, indicating effective secondary surveillance potential.

Impact: The study demonstrates that abbreviated MRI can effectively monitor HCC post-treatment, offering a less burdensome and cost-effective surveillance method with high accuracy, paving the way for streamlined clinical monitoring protocols.
