Scaphoid, the tubercle of trapezium (radial-sided pain), the hook of the Of bone contusion are differentiated mainly by the absence of a clearįracture line (Figure 2). T1-weighted sequence with surrounding bone marrow edema (Figure 1).Areas Occult fractures are detected as linear, low signal intensity on the Of clinical-radiological mismatch in which surgery is being considered. Sequences, the authors perform 3T MRI as a default at our institution,Īnd reserve arthrography for selected postoperative cases, or for cases Technological advances in MRI systems, dedicated coils and new However, whetherĪrthrography is necessary for all cases remains unclear. These techniques, particularly of 3T MR arthrography. Standard of care in many institutions for assessing internalĭerangement,as multiple studies demonstrate the accuracy advantage of Or indirect MR arthrography (for both 1.5T and 3T) is employed as the Preferable to 1.5T, given the better signal-to-noise ratio, contrast,Īnd resolution of the images, all of which increase diagnostic accuracy. Turbo spin echo proton density fat saturation sequences), which allowsįor multiplanar reconstruction in isotropic acquisitions. To 1mm) is normally added (2D or 3D GRE T2* or more recent volumetric3D Section thickness varies from 2mm to 3mm. It employs a small field of view (8 to 10 cm), and While varying among institutions, a typical wrist MRI protocol is The wrist, including post-traumatic lesions, avascular necrosis,Ĭhondral injuries and arthritis,tendon pathologies and internalĭerangements of ligaments and the triangular fibrocartilage complex This article will discuss typical indications for advanced imaging of Surgical diagnosis and management of wrist pathologies. Imaging without employing ionizing radiation. Magnetic resonance imaging represents a relevant way toĭiagnostically assess the wrist with high-resolution, multiplanar
