The Research of Curative Effect Evaluation of Diffusion-weighted Imaging on Hepatocellular Carcinoma after Transcatheter Arterial Chemoembolization Treatment
Abstract：Objective:To investigate the judgment value of diffusion-weighted imaging on the tumor survival of hepatocellular carcinoma after transcatheter arterial chemoembolization treatment.Method:A total of 35 patients with transcatheter arterial chemoembolization treatment according to chemoembolization protocols in our hospital were selected as research objects.After 8 weeks,they underwent enhanced magnetic resonance imaging and DWI scan on the same day. The presence of any residual tumor and the extent of tumor necrosis were evaluated according to the European Association for the Study of the Liver.The apparent diffusion coefficient (ADC) values of the vital and necrotic tumor tissues were recorded.Result:The mean ADC values of the necrotic and vital tumor tissues were (2.03±0.27)×10-3 mm2/s and (1.55±0.28)×10-3 mm2/s,the difference was statistically significant(P<0.05).The results from the receiver operating characteristic analysis showed that the threshold ADC value was (1.91±0.18)×10-3 mm2/s with 89.2%sensitivity and 91.6%specificity for identifying the necrotic tumor tissues. Conclusion:Diffusion-weighted imaging can be used to assess the tumor necrosis and residual tumor of hepatocellular carcinoma after TACE treatment,provide the basis data for clinical treatment.
