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.
