3D DCE MRA在原发性肝癌诊断中的临床应用

目的：探讨单次屏气三维对比增强磁共振造影(3D DCE MRA)在原发性肝癌中的检查技术及临床应用。方法：回顾性分析23例原发性肝癌的3D DCE MRA表现。对原发性肝癌肝动脉期、门静脉期分别进行扫描和重建。结果：肝动脉期可显示肝癌供血动脉血管7例，动静脉瘘6例，肝动脉受挤压变形6例。门静脉期显示门静脉高压18例。门静脉癌栓13例，肝内门静脉受压移位3例。结论：有效地抓住对比剂在各靶血管中的有效浓度，可分别显示肝癌的血供情况、血管破坏情况、门静脉开放程度，为临床治疗提供有价值的影像参考。

The clinical application of 3D DCE MRA in the evaluation of the primary hepatocellular carcinoma

Objective:To investigate the techniques and the clinical application of 3D DCE MRA in the evaluation of the hepatocellular carcinoma (HCC).Methods:The appearances of 3D DCE MRA in 23 cases of HCC were retrospectively analyzed.The arterial and portal venous phase was scanned and reconstructed separately.Results:During the arterial phase,abnormal enhancement of tumor feeding vessels and neoplastic vasculature were shown in 18 cases,arteriovenous fistula (AVF) were shown in 6,compression and displacement of intrahepatic arteries in 6.During the portal venous phase,portal hypertension was shown in 18 cases,tumor thrombosis of the main portal vein was shown in 13,compression and displacement of intrahepatic portal vein were shown in 3.Conclusion:3D DCE MRA can clearly demonstrate the blood supplies of HCC,the involvement of vessels,and the morphology and patency of portal vein.It provides important information for treatment planning of HCC.
