摘要

目的:探讨肝脏快速容积采集（Liver acquisition volume acceleration

LAVA）整合阵列空间敏感编码技术（Arrayspatial sensitivity encoding technique

ASSET）在显示肝癌血管解剖信息中的价值。方法:对42例有手术病理结果的肝癌病例的肝脏常规MR平扫及增强扫描资料进行回顾性分析。增强扫描采用LAVA整合ASSET;将LAVA采集的原始图像进行最大密度投影（Maximum intensity projection

MIP）处理并分析其对肝脏占位性病变及肝血管关系的显示情况及其整合ASSET后缩短采集时间的优势。结果同手术病理所见对照。结果:42例44个占位性病变全部清晰显示。整合ASSET后采集时间明显缩短

24例实现动脉早期和动脉期采集;18例患者实现动脉早期、动脉期和动脉晚期采集。动脉期经MIP后处理显示肿瘤血管30例

肿瘤供血动脉明显增粗、变形、移位20例

动静脉瘘1例。门脉期经MIP后处理检出肿瘤对门静脉的侵犯25例

门静脉癌栓6例。MIP显示肿瘤血管、供血动脉的来源分布及门静脉癌栓与手术病理结果基本一致。结论:LAVA整合ASSET在肝脏动态扫描中可在较短时间内获得多期高质量增强图像并提供血管解剖信息

具有较高应用价值。

Abstract

Objective:To evaluate the application value of liver acquisition volume acceleration(LAVA)integrated with array spatial sensitivity encoding technique(ASSET)in demonstrating the vasculature of the liver carcinoma.Methods:42 patients with liver carcinoma underwent routine and contrast-enhancement MR examination of liver.LAVA integrated with ASSET was used in contrast-enhancement MR examination.The ability of LAVA integrated with ASSET to reveal the lesion and the hepatic vessels and the advantage to shorten the acquisition time were analyzed.Results:44 foci were revealed clearly.After integrated with ASSET

acquisition time shortened.Earlier and peak artery phase images were obtained in 24 cases

and earlier

peak and late artery phase images were acquired in 18 cases.Using MIP technique

tumor vessels were found in arterial phase images in 30 cases;tumor supply arteries were found in 20 cases;arteriovenous shunt was found in 1 case;portal vein invasion was found in 25 cases

and portal vein tumor embolus was found in 6 cases.Conclusion: LAVA integrated with ASSET has high application value

which can obtain high quality multi-phase dynamic enhancement images in a short time and supply the information of the anatomy of hepatic vessels.
