【摘要】 目的　探讨螺旋CT双期扫描对肝脏占位性病变的诊断价值。方法　对 98例肝内占位性病变的病人进行螺旋CT双期增强扫描。结果　 98例病人中肝癌 48例 ,肝转移瘤 19例 ,肝血管瘤 31例。结论　螺旋CT扫描速度快 ,在动脉期和门静脉期分别完成全肝扫描 ,弥补了一般动态扫描的缺点 ,对肝内病灶的检出和定性有重要价值。更多还原

【Abstract】 Objective To evaluate dual phase helical CT in the diagnosis of hepatic lesions.Methods Dual phase scanning of the liver in 98 patients with lesions was carried out with a helical CT scanner.Results Significant difference was found in dual phase helical CT about liver lesions.There were 48 hepatic tumor,19 metastases,31 hemangiomas in the remaining 98 patients.Conclusion Helical CT scanning is faster than enventional scanning.The arterial phase and portal venous are performed in all liver.Therefore,it is important to use helical CT detecting characterization of hepatic lesions.更多还原
