ABSTRACT
Objective@#To evaluate the value of super microvascular imaging(SMI) for evaluating the effect of interventional therapy of liver cancer.@*Methods@#A total of 30 patients with 40 leisions were enrolled in this study, from the tumor intervention department in the third affiliated hospital of suzhou university.This patients were underwent TACE, after the treatment 1 month, CDFI, SMI, and CT were study respectively. Using the continuity correction McNemar matching chi-square test, with P < 0.05 for the standard , CDFI and SMI shows the difference in monitoring the microvascular imaging in and around the tumors leisions.@*Results@#A total of 30 patients, 12 cases were primary liver cancer (7 cases combined with liver cirrhosis), 18cases were metastatic liver cancer; 30 cases including 25 single and 5 multiple. Significant difference were found between CT and SMI in detecting blood flows inside the lesion (χ² = 8.642 9, P < 0.05), and were also found between CT and CDFI in detecting blood flows inside the lesion (χ² = 16.961 5, P < 0.05). The AUROC, sensitivity, specificity, accuracy, PPV and NPV of CDFI were 0.647, 29.4%、100%、29.4%、100%、20.0%, while in SMI were 0.809, 61.8%、100%、61.7%、100%、31.5%, respectively.@*Conclusions@#SMI SMI can detect the microvascular inside the lesions. This new method was superior to CDFI, achieving the same effect as CT.
