MR and CT arthrography of the wrist.
The study of the wrist represents a major diagnostic challenge because of its complex anatomy and the small size of individual structures. Recent advances in imaging techniques have increased our diagnostic capabilities. However, 3T magnets, multichannel specific wrist coils, and new MRI sequences have not restricted the indications of arthrographic imaging techniques (CT arthrography and MR ar...
متن کاملMR and CT arthrography of the hip.
CT arthrography (CTa) and MR arthrography (MRa) are useful tools for the investigation of intra-articular hip disease. They are minimally invasive techniques with a very low rate of complications and can be performed safely. CTa or MRa can be performed after an intra-articular injection of diluted contrast, but both techniques can also be performed after a single injection. As radiologists we s...
متن کاملMR and CT arthrography of the shoulder.
The combined use of shoulder arthrography with MR and CT imaging offers distinct advantages over conventional nonarthrographic imaging techniques. The improved contrast and joint distension afforded by direct arthrography optimize evaluation of various intra-articular structures and help to define subtle abnormalities and distinguish normal variants from true shoulder pathology. In this article...
متن کاملMorbidity of direct MR arthrography.
OBJECTIVE The purpose of this study was to determine the incidence and severity of arthrographic pain after intraarticular injection of a gadolinium mixture diluted in normal saline for direct MR arthrography. SUBJECTS AND METHODS From March 2009 until January 2010, 155 consecutive patients underwent direct MR arthrography; 20 patients were lost to follow-up. Patients were contacted by teleph...
متن کاملMR-arthrography and CT-arthrography in sports-related glenolabral injuries: a matched descriptive illustration
The combination of a large range of motion and insufficient bony stabilization makes the glenohumeral joint susceptible to injuries including dislocation in young athletes. Magnetic resonance arthrography (MR-arthrography) and computed tomography arthrography (CT-arthrography) play an important role in the preoperative workup of labroligametous injuries. This paper illustrates MR-arthrography a...
