Abstract: Objective To compare the value of biphasicmulti-detector row helical computed tomogrpahy(MDCT),digital subtraction angiography(DSA)and lipiodol computed tomography(CT)in hypervascular hepatocellular carcinoma(HCC).Methods 80 cases with liver cancer were underwent MDCT、DSA、iodized oil CT scan,then compared detection rates of three methods.Results In detecting hepatic nodules(＞2cm),these three imaging techniques had the same sensitivity;for 1～2cm hepatic nodules,the detecting rate had no significant difference;The MDCT scan＜1cm detected 47 nodules(94.0%),iodized oil CT detected 27 nodules(54.0%),both statistically significant difference in detection rate(χ~2=3.11,P＜0.01),DSA is only detected 16 nodules(32.0%)compared with enhanced dual-phase MDCT scan and iodized oil CT detection rate the differences were statistically significant(χ~2=9.09,9.03,all P＜0.01).Conclusion MDCT is able to better show feeding arteries of hepatocellular carcinoma,The imaging examination of liver cancer before treatment can be used as a comprehensive evaluation.
