We aimed to compare diagnostic performance of gadoxetic-acid-enhanced-T1-weighted-MR cholangiography (MRC) with that of conventional T2-weighted-MRC in diagnosing biliary stone disease.
Ninety patients who underwent MRC for evaluation of biliary disease were included. Presence of stones in extrahepatic duct, gallbladder and intrahepatic duct, and presence of acute cholecystitis were evaluated. Sensitivity, specificity, and accuracy of biliary stone disease diagnosis in each biliary duct location according to each image sets were measured.
There was no significant difference in diagnostic performance between two sets of MRC in diagnosing biliary stone disease.
Diagnostic performance of T1-MRC with gadoxetic-acid in diagnosing biliary stone disease is comparable to that of T2-MRC.
本研究旨在比较钆塞酸增强 T1 加权磁共振胆胰管成像（MRC）与常规 T2 加权 MRC 诊断胆石病的诊断性能。
本研究纳入了 90 例行 MRC 检查以评估胆道疾病的患者。评估肝外胆管、胆囊和肝内胆管结石的存在情况以及急性胆囊炎的存在情况。根据每个图像集测量每个胆道位置诊断胆道结石病的敏感性、特异性和准确性。
两种 MRC 方案在诊断胆道结石病方面的诊断性能无显著差异。
钆塞酸增强 T1-MRC 诊断胆道结石病的性能与 T2-MRC 相当。
