Abstract:
Objective To compare the value of computed tomography(CT)and magnetic resonance im-aging(MRI)in assessing the curative effect of primary liver cancer after transcatheter arterial chemoembolization (TACE). Methods 45 patients with primary hepatocellular carcinoma treated with TACE for 3 ～ 5 times were included in the research. CT ,MRI and digital subtraction angiography (DSA) were performed after treatment. DSA was used as a standard to analyze the lesions ,residual or lesion recurrence and the detection of tumor cap-sule in CT and MRI DSA. Results The scanning accuracy and sensitivity of residual lesions or lesion recurrence after TACE in CT was much lower than MRI ,and there is a significant difference between the two groups (P <0.05). In terms of tumor capsule detection accuracy after TACE ,CT was much lower than MRI(P < 0.05). In detection rate of residual or lesion recurrence in different types of lipiodol deposition after TACE ,CT was much lower than MRI (P < 0.05). Conclusions Compared with the CT test ,MRI detection has a higher accuracy and sensitivity of residual lesions or recurrence after TACE. MRI can not only effectively show the tumor cap-sule ,but also detect residual lesion or lesion recurrence of different types of lipiodol deposition. MRI is superior to CT in the evaluating the curative effect of primary liver cancer after TACE.
