中文摘要 | 磁振膽道造影(MR Cholangiography)是一項非侵入性可評估病患膽道疾病的新方法。本研究探討磁振膽道影像是否能夠提供有用的膽道影像,並與經皮穿肝膽道攝影及逆行性內視鏡膽道攝影兩膽道影像比較。 20位膽道患者執行2維及3維之磁振造影以heavily T2-weighted gradient-echosequence技術獲得膽道影像,包括病變在肝門者有7位,在總膽管者有6位,另外7位為結石患者(4位則同時具有肝內及膽管結石),20位中有15位由手術或病理證實,另5位則經由臨床追蹤及電腦斷層、超音波影像診斷來確定。在20位中16位曾有執行逆行性內視鏡膽道攝影及13位曾執行經皮穿肝膽道攝影。 所得結果發現具有良好影像滿意率於2維磁振膽道影像、3維磁振膽道影像、經皮穿肝膽道攝影及逆行性內視鏡膽道攝影分別為75%、45%、69%、及31%。雖然2維磁振膽道影像之滿意成像之成功率遠優於傳統之皮穿肝膽道攝影及逆行性內視鏡膽道攝影,但立體重構組成之影像較粗燥。3維磁振膽道影像可改善2維磁振膽道影像,但由於必須較長的閉氣時間,導致成像品質不佳。 結論:磁振造影可以提供非侵襲性的膽道評估,並且可以同時找出肝內或膽道內之病灶,但目前影像品質仍有改善之空間。 |
英文摘要 | MR cholangiography (MRC) is a newly developed non-invasive imaging modality for the evaluation of biliary tract diseases. In this prospective study, we investigate whether MRC may provide valuable cholangiographic images. As well we compare MRC with PTC and ERC in the diagnosis of biliary tract disease. Twenty patients simultaneously underwent a heavily T2-Weighted gradient-echo sequence of two-dimentional (2D)-and three dimentional (3D)-MRC. Among these 20 patients with obstructive jaundice, the distribution of lesions were as follows:7 at liver hilum; 6 at the CBD; and 7 with bile duct stones (including 4 with concurrent CBD and IHD stones). Sixteen out of the 20 patients underwent ERCP and 13 patients, PTCD. The images were evaluated without prejudicial selection. Imaging of the biliary system was satisfactory in 75%, 45%, 69% and 31% for 2D-MRC, 3D-MRC, PTCD and ERCP respectively. Although the rate of well-performed images in 2D-MRC are fuzzy. 3D-MRC reconstructional imaging provides better quality than that of 2D-MRC, but is accompanied by a higher failure rate due to motion artifact. |
