多层螺旋CT多期增强扫描在原发性肝癌诊断中的应用价值

Diagnosing Value of Multiple-phase Scanning of multi-spiral computer tomography on Primary Liver Cancer

目的探讨多层螺旋CT(MSCT)多期增强扫描在原发性肝癌(PLC)诊断中的价值。方法回顾性分析2013-01~2016-10该院收治的96例经临床确诊为PLC的患者MSCT图像资料,总结其图像特征。结果 96例中共检出396个病灶。平扫发现64例(66.7%),表现为低密度或以低密度为主;多期增强扫描:动脉期有93例(96.9%)显示为不均匀高密度强化,内可见细小肿瘤血管影,门静脉期有78例(81.3%)显示为病灶强化逐渐减退,延迟期有89例(92.7%)显示为病灶强化继续减退,呈低密度改变,整个强化过程表现为"速升速降"特征。结论 MSCT多期扫描能更清楚地显示PLC的特征,对PLC的早期诊断具有较高的临床价值,值得推广应用。

Objective To evaluate the diagnosing value of multiple-phase scanning of multi-spiral computer tomography（MSCT） on primary liver cancer. Methods From January 2013 to October 2016, ninety-six patients proven by histological examination as primary liver cancer（PLC） were included in this study. The imaging data of MSCT scanning of the patients were analyzed retrospectively. Results There were 396 lesions in 96 patients. Scan mode detected that the signal of 64 （66.7%） cases was low density or mainly low density, and there were 93 （96. 9% ） cases with high density in arterial phase. There were 78（81.3% ） cases with low density in portal vein phase, and 89（92.7% ） cases with low density in delay phase, which presented as＂quick ascent and quick de- scent＂. Conclusion MSCT can clearly reflect PLC, which has a higher clinical value on diagnosing PLC.
