Comparison of Abbreviated MRI with Hepatobiliary Phase Sequences versus Full Protocol MRI in Post-Microwave Ablation Surveillance of HCC

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.
