MR arthrography of the wrist is a valuable tool for the diagnosis and evaluation of a wide spectrum of acute and chronic articular disorders.The method has the potential of replacing diagnostic arthroscopy for the evaluation of the triangular fibrocartilage complex and the intrinsic and extrinsic ligaments. High resolution MR imaging with a dedicated coil is essential for detecting partial thickness tears. Abnormalities, such as leakage of injected contrast agent from one compartment into another are common in asymptomatic subjects. An optimal communication concerning clinical symptoms between the radiologist and referring clinician is essential not to overreport abnormalities without clinical importance. Awareness of normal variants and pitfalls is essential. Combining iodinated and gadolinium based contrast agents for MR arthrography may have additional value.
腕关节磁共振关节造影是诊断和评估多种急慢性关节疾病的重要工具。该方法有可能替代诊断性关节镜检查来评估三角纤维软骨复合体以及内在和外在韧带。使用专用线圈进行高分辨率磁共振成像对于检测部分厚度撕裂至关重要。在无症状受试者中，诸如注入的造影剂从一个腔室漏入另一个腔室等异常情况很常见。放射科医生与转诊临床医生之间就临床症状进行最佳沟通对于不过度报告无临床意义的异常情况至关重要。了解正常变异和陷阱至关重要。联合使用碘造影剂和钆造影剂进行磁共振关节造影可能具有额外价值。
