Title: Diagnostic value of 3-dimensional dynamic contrast-enhanced magnetic resonance angiography before liver tansplantation
Abstract: Purpose To evaluate the diagnostic value of three-phase scan technology of 3D DCE MRA(3-dimensional dynamic contrast-enhanced magnetic resonance angiography) before liver transplantion.Methods 3D DCE MRA was performed on 183 patients before liver transplantion,using Siemens Symphony 1.5T superconduct MRI machine,circular polarized phased-array coil,three-phase(arterial phase,portal venous phase,and venous phase)3D DCE MRA;the images were assessed synthetically.Results Satisfactory angiographic images were obtained in all patients.The grade 2-3 branches of the hepatic artery,the grade 2-5 branches of the portal vein,and the grade 1-2 branches of the hepatic vein could clearly be visualized.Of 183 cases of liver transplatation,there were 5 cases of variations of hepatic artery,and among them 2 cases came from superior mesenteric artery,2 cases from celiac truncus,and one from left gastric artery.There were 103 cases of hepatocirrhosis with portal hypertension among 183 cases of liver transplatation,including 23 cases of varicosity of coronal vein or esophageal vein, 5 cases caput medusae,2 cases of mesenteric vein varicosity,and 30 cases of varicose vein around the splenic hilus,and 1 case of hyaline degeneration of portal vein.There were 79 cases of hepatocarcinoma,including 5 cases of hepatic artery embedding,rigidity or shift, 2 cases of hepatic arteriovenous fistula.35 cases of portal vein tumor thrombus(23 in right portal vein,7 in left portal vein,3 in portal vein truncus,and 2 in right and left portal veins),7 cases of hepatic vein tumor thrombus,1 case of inferior vena cava embolism,and 5 cases of inferior vena cava shift.Conclutions In most cases,three-phase 3D DCE MRA clearly demonstrates lesions in the hepatic arteriy,portal vein,hepatic vein,and inferior vena cava simultaneously.Application of 3D DCE MRA before liver transplantation can basically meet the clinical requirements;it is an efficient method for preoperative blood vessel evaluation.
