磁共振成像对原发性肝癌碘油栓塞治疗后的随访价值

The follow-up analysis of MRI in patients with hepatocellular carcinoma treated by transcatheter arterial chemoembolization with lipiodol

目的探讨MRI对评判经碘油栓塞治疗后原发性肝癌(HCC)的疗效。方法选择我院收治的42例HCC患者,共49个病灶。在经碘油栓塞(TACE)治疗后,21例行MRI检查及病理切片观察,观察MRI影像表现及检出准确率。结果 MRI平扫表现为肿瘤组织在T1WI和T2WI上信号多样,有高、等、低信号或多种信号复合。切片观察显示,34个病灶中,18个有不同程度的坏死,7个完全坏死,9个无坏死。共有25个病灶MRI检查显示为坏死,6个检查为残留,检查准确率为91.2%(31/34)。结论 MRI在判断HCC碘油栓塞治疗的预后中,检出率高,能有效反映病灶特征,值得推广。

Objective To diseuss the effieaey evaluated by MRI in patients with hepatoeellular carcinoma（HCC） treat- ed by transeatheter arterial chemoembolization （TACE） with lipiodol. Methods Selected 42 eases of HCC patients with 49 lesions in our hospital. MRI and pathologieal examination were used for 21 cases after treatment by TACE. And then observed and compared the MRI imaging results and the aeeuraey of detection. Results MRI plain seanning showed the tumor tissue on T1WI and T2WI were with diverse signal. Sliee observation showed 34 lesions, 18 eases had varying degrees of necrosis, 7 eases were complete neerosis, 9 cases were no neerosis. In MRI test, there were 25 lesions were neerosis and 6 lesions were residual, the aeeuraey rate were of 91.2%（31/34）. Conclusion MRI in foreeast the prognosis of HCC treated by TACE, is of a higher detection ratio, it can refleet the characteristics of lesions more effective . It is worthy of clinical use.
