Objective To compare the value between multi-slice spiral computed tomography (MSCT) and gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) enhanced magnetic resonance imaging (MRI) in the follow-up of primary hepatic cancer (PHC) after transcatheter hepatic arterial chemoembolization (TACE).
Methods A total of 106 patients with PHC were selected. The accuracy, sensitivity and specificity of MSCT and Gd-DTPA enhanced MRI in the diagnosis of tumor residue and recurrence were compared based on the results of digital subtraction angiography (DSA).
Results There were 146 lesions in 106 patients before operation, 43 of which had residual tumors, and the accuracy, sensitivity and specificity of MSCT in diagnosing residual tumor were 86.30%, 81.40% and 88.35% respectively, which were significantly lower than 95.89%, 95.35% and 96.12% of Gd-DTPA enhanced MRI (P < 0.05); a total of 37 lesions had recurrence, and the accuracy, sensitivity and specificity of MSCT in diagnosing tumor recurrence were 88.36%, 80.56% and 90.91% respectively, which were significantly lower than 97.26%, 97.22% and 97.27% of Gd-DTPA enhanced MRI (P < 0.05).
Conclusion Gd-DTPA enhanced MRI is superior to MSCT in the diagnosis of tumor residue and recurrence after TACE in patients with PHC.
