Abstract: Objective To compare the two methods of 3D contrast-enhanced MRA in the diagnosis of upper extremity disea-ses, and also to explore the advantages of the moving-bed technique .Methods Two groups of 20 patients suspected of having upper extremity arterial diseases underwent detections of the non-moving-bed 3D contrast-enhanced MRA and the moving-bed 3D contrast-en-hanced MRA .Results Clear pictures of culprit lesion in the upper extremities ( arterio-venous malformation , hemangioma ) were dis-played in all the 20 cases, and the pictures of upper extremity blood vessel were clearly shown during the whole process in 8 cases, with clear direction of blood supply .Conclusion As compared with the non-moving-bed 3D contrast-enhanced MRA, the moving-bed 3D contrast-enhanced MRA had the following advantages:better continuity and more comprehensive assessment of the nature of upper ex-tremity blood vessel lesion .With this reason, it was a detection technique worth further clinical extension .
