A Comparative Study of CT and MRI in the Follow-up of Hepatocellular Carcinoma after Transcatheter Arterial Chemoembolization with Lipiodol / 实用放射学杂志

ABSTRACT

Objective To compare the ability of CT and MRI in evaluating the residual of tumor of hepatocellular carcinoma (HCC) and its stability after treated by transcatheter arterial chemoembolization (TACE) with Lipiodol.Methods 28 patients with HCC underwent CT, MRI and angiography within 2～6 months after 1～4 procedure(s) of TACE. These three examinations were completed sequentially within one month. CT and MRI findings were thus compared on the basis of the results of arteriography and clinical follow-up at least 6 months.Results 46 lesions were found in 28 patients. 31 lesions with and the other 15 lesions without residual viable tumor were confirmed by arteriography and clinical follow-up. 20 lesions with and 26 lesions without residual viable tumor were found on CT images, and CT displayed 64.5% sensitivity, 100% specificity, and 76.1% accuracy respectively. 29 lesions with and 17 lesions without residual viable tumor were found on MRI images, and its sensitivity, specificity, and accuracy were 93.5%, 100%, and 95.7% respectively. The sensitivity and accuracy between CT and MRI in evaluating the residual viable tumor of HCCs after TACE were significant different(?
