螺旋CT在诊断肝脏局灶性占位性病变中的应用研究

目的:探讨螺旋CT在肝脏局灶性占位性病变中的诊断及鉴别诊断价值,进一步提高CT对疾病诊断的准确性。方法:回顾性分析50例肝脏局灶性占位性病变病例的平扫及动态增强扫描征象。结果:50例病例中,良性病变21例,恶性病变29例,其平扫几均表现为低密度,高血供病变在动脉期呈现高密度,少血供的病变,门脉期扫描病灶可为明显低密度易被显出,部分病灶有延迟强化之特点,与其良恶性无必然联系。结论:螺旋CT结合高压注射器的使用及多期扫描特点,对正确诊断肝脏局灶性占位性病变具有重要价值。

Clinical Application of SCT in Focal and Occupied Diseases in Liver

Objective To discuss the value of spiral CT in diagnosis and differential diagnosis of focal and occupied disease of liver, then to improve the accurate rate of the occupied diseases in liver by CT scan. Methods SCT studied of 50 cases with focal and occupied diseases in liver were reviewed retrospectively .All patients underwent including plain CT scan and dynamic enhanced scans. Results In 50 cases ,21 cases of benign disease,29 cases of malignant disease, all appeared as lower density in plain CT scan. The focus of vascularity abundantly demonstrated hypcrdense regions in the arterial phase, those focus lacking vascularity be found hypodensity in the vena portae phase easily, some regions appears enhancement in delay time. There is no inevitable contact between them. Conclusion SCT with usage of high pressure injection and characteristics in multi phases scan, so CT plays an important role in diagnosis the disease accurately.
