原发性肝癌TACE前后MRI与DSA对比研究

Comparative Study of MRI and DSA of Hepatocelluar Carcinoma before and after Transcatheter Arterial Chemoembolization

目的研究MRI对原发性肝癌(HCC)行肝动脉栓塞化疗(TACE)术后的随访价值。材料和方法对39例原发性肝癌患者分别于TACE术前一周及术后一月行MRI和DSA检查,比较MRI和DSA对于TACE术前肝癌病灶显示及TACE术后肝癌病灶的残留及复发情况。结果 TACE术前肝癌病灶检出数DSA与MRI比较无统计学意义,但对1cm以下富血供肝癌二者比较有差异。一次及多次TACE术后残留病灶及新发病灶检出数比较无统计学意义。结论 MRI能够较敏感地显示肝癌病灶及TACE术后肝癌残留病灶,使TACE治疗更具有针对性,评价TACE栓塞效果完全可行,可作为肝癌介入治疗后随访方法。

Objective To study the value of MRI in the follow-up of hepatocellular carcinoma （HCC） treated with transcatheter arterial chemoembolization （TACE）. Materials and Methods In total 39 cases of HCC, MR/and DSA were performed 1 week before and 1 month after TACE. Hepatic lesions detected by MRI and DSA was analyzed and compared before and after TACE. Results In detecting hepatic lesions, MRI and DSA had the same sensitivity, while for 〈 1 cm hepatic lesions which had abundant blood supplies,＇ thedetecting rate was significant different between them. Compared with DSA, MRI had the same sensitivity to find residual tumors and new lesions after TACE. Conclusion MR/can demonstrate sensitively hepatic lesions and residual tumors, and cause TACE to treat pointedly. It is completely feasible to evaluate the effect of TACE, and may be a followup method of HCC treated with TACE.
