摘　　要：目的探讨肝脏恶性肿瘤在Gd-BOPTA增强MR延迟像上的表现,为Gd-BOPTA增强MR对肝肿瘤的诊断提供依据。方法收集Gd-BOPTA增强扫描的肝脏恶性肿瘤病灶29例,图片分为MR平扫、Gd-BOPTA延迟增强扫描两组,对比分析病灶数目、边界、信号强度以及延迟像胆道系统强化情况。结果延迟像中所有病灶边缘均清晰、锐利。病灶可出现强化但信号均低于肝脏。延迟像肝外胆道及肝内胆管一级分支可见明显强化。结论Gd-BOPTA延迟扫描中,肝脏恶性肿瘤边界清晰,信号强度低于肝脏,此特征可作为Gd-BOPTA增强MR诊断肝脏肿瘤的参考依据。Objective To study the manifestation of hepatic malignant neoplasm on static Gd-BOPTA enhanced MR imaging, which supports the diagnosis of hepatic malignant neoplasm using Gd-BOPTA enhanced MR imaging. Methods In total 29 lesions of hepatic malignant neoplasm underwent both non-enhanced MR imaging and Gd-BOPTA enhanced MR imaging. The images were divided into non-enhanced and static groups. The number, margin, signal intensity of lesions and bile duct system manifestations obtained in the delayed enhanced scan were analyzed respectively. Results All the marginal area of lesions was clear and sharp. The lesions were enhanced while their signal intensity were lower than that of adjacent liver. On static phase all the extra-hepatic bile passages and the first class branches of intrahepatic bile ducts were well enhanced. Conclusion In static Gd-BOPTA enhancd MR imaging boundaries of neoplasm lesions were clear and sharp, with a lower signal intensity than liver. This feature may support the diagnosis of hepatic malignant neoplasm using Gd-BOPTA enhanced MR imaging.
