Magnetic resonance imaging (MRI) is an established imaging method in abnormalities of the wrist. Inherent advantages of this imaging method such as the lack of ionizing irradiation, the free choice of imaging planes and its excellent contrast resolution have been enhanced by the introduction of surface coils and new sequences. These developments result in an improved spatial resolution, allowing imaging of small structures such as the triangular fibrocartilage. There is a number of established indications for MRI of the wrist, e.g. diagnosis of avascular necrosis, follow-up after carpal tunnel surgery and imaging of soft tissue masses. Increasingly, MRI can be used for the diagnosis of intercarpal ligament tears as well. The diagnostic capabilities of MRI of the wrist are discussed, based on personal experience and a review of the literature.
磁共振成像(MRI)是腕部异常情况的一种成熟成像方法。这种成像方法的固有优势,如无电离辐射、可自由选择成像平面以及出色的对比分辨率,通过引入表面线圈和新序列得到了增强。这些进展提高了空间分辨率,使得诸如三角纤维软骨等小结构能够成像。腕部MRI有许多既定的适应证,例如诊断缺血性坏死、腕管手术后的随访以及软组织肿块的成像。MRI也越来越多地用于诊断腕骨间韧带撕裂。基于个人经验和文献综述,对腕部MRI的诊断能力进行了讨论。
