The application value of conventional ultrasound and 16-slice CT examination in the clinical diagnosis of HCC and hepatic focal nodular hyperplasia / 中国医学装备

ABSTRACT

Objective: To investigate the application of conventional ultrasound and 16-slice CT examination in clinical diagnosis of hepatocellular carcinoma (HCC) and hepatic focal nodular hyperplasia. Methods: To choose 94 cases patients were receiving treatment in our hospital who were diagnosed as hepatic focal lesion through percutaneous biopsy of hepatocyte or histopathological examination of postoperation, and then take conventional ultrasound and 16-slice CT, respectively, to detect them. To compare and analyze the two methods in series of indicator, such as accuracy, the number of lesion size and the imageology character. Results: Conventional ultrasound diagnosis of benign tumor lesions was consistent with spiral CT results, and the difference was not statistical significance (x2=0.5556, P>0.05). The accuracy of spiral CT for hepatic carcinoma was higher than that of conventional ultrasound, and the difference was significant (x2=8.1987, P<0.05). The consistent rate of the spiral CT group with real result for micro-miniature carcinoma (the diameter less than 1 cm) was higher than that of conventional ultrasound group, and their difference was significant (x2=14.4028, P<0.05). The disappear and persist time of hepatic carcinoma patients were longer than that of non-hepatic carcinoma patients, and the difference between them was significant (t=9.7531, P<0.05). Conclusion: It is higher accuracy that 16-spiral CT can diagnose malignancy lesions in earlier stage.
