低剂量 MSCT在肝癌患者腹部检查中的应用
Low-Dose Multi-Slice Computed Tomography Applied to Abdomen Examination of Patients with Hepatocellular Carcinoma
摘要
Abstract
Objective To explore the value of low-dose multi-slice computed tomography(MSCT) in reducing the radiation dose of abdominal CT for patients with hepatocellular carcinoma .Methods Twenty-seven patients with hepatocellular carcinoma underwent conventional-dose MSCT examination by spiral scan at the first visit (conventional-dose scan group),and underwent low-dose MSCT examination by axial scan at the return visit (low-dose group).Both groups were examined with the voltage of 120KV,automatic tube current modulation (ATCM) and noise index of 9, and plain scans,arterial phase scans as well as portal venous phase scans were performed ,respectively.The image quality score,noise index and radiation dose were compared between the two groups between the two groups .Results The image quality scores and noise indices of plain scans ,arterial phase scans and portal venous phase scans showed no significant difference between two groups(P>0.05).The effective radiation dose in the low-dose group was significantly lower than that in the conventional-dose scan group (P<0.05).Conclusion Axial scan and ATCM may effectively reduce the radiation dose of abdominal MSCT scanning in patients with hepatocellular carcinoma ,which can provide excellent MSCT scanning images.关键词
