Radiologic Monitoring of Hepatocellular Carcinoma Tumor Viability after Transhepatic Arterial Chemoembolization: Estimating the Accuracy of Contrast-enhanced Cross-sectional Imaging with Histopathologic Correlation

Contrast-enhanced CT and MR imaging after chemoembolization are associated with high error rates. Between the two modalities, MR has higher sensitivity and specificity and may be a preferable imaging tool for patients who have undergone chemoembolization.
