The ability of both imaging modalities to differentiate between surviving, new, or necrotic lesions was assessed, using digital subtraction angiography (DSA) or interventional diagnostic results as the reference standard. Detection rates were compared using the chi-square test, while sensitivity, specificity, and accuracy were analyzed with McNemar’s test.ResultsAfter applying inclusion and exclusion criteria, 48 patients were eventually included in the analysis. The reference standard identified 14 cases of surviving lesions, 19 of new lesions, and 15 of necrotic lesions. Gd-EOB-DTPA-enhanced MRI demonstrated a sensitivity of 93.9% (31/33), specificity of 100% (15/15), and a Youden index of 0.939, whereas CECT exhibited a sensitivity of 51.5% (17/33), specificity of 60.0% (9/15), and a Youden index of 0.115.ConclusionThe findings indicate that Gd-EOB-DTPA-enhanced MRI possesses superior diagnostic value for evaluating lesion status in HCC post-TACE compared to CECT, as evidenced by significant differences in sensitivity and specificity (p < 0.05).
