Magnetic resonance (MR) imaging of the wrist was performed in 35 patients with specific complaints of pain and soft-tissue swelling in the medial side of the wrist. Twenty of the 35 subsequently underwent surgery. In 14 of the patients who underwent surgery, a diagnosis of triangular fibrocartilage (TFC) tear was made at MR imaging; in 13 of the 14 the tear was confirmed by surgical findings. In the six patients with an MR diagnosis of an intact TFC, surgical findings confirmed the diagnosis. These patients were operated on for an abnormality in the vicinity of the TFC (avascular necrosis, ganglion cyst, xanthoma). On the basis of findings from the 20 patients with surgical correlation, the accuracy of MR imaging in the detection of TFC tears was 95%. MR imaging is a valuable noninvasive method in the study of pathologic conditions of the TFC.
对35例有手腕内侧疼痛和软组织肿胀特定主诉的患者进行了手腕磁共振（MR）成像检查。35例患者中有20例随后接受了手术。在接受手术的14例患者中，MR成像诊断为三角纤维软骨（TFC）撕裂；14例中的13例撕裂经手术结果证实。在MR诊断为TFC完整的6例患者中，手术结果证实了该诊断。这些患者因TFC附近的异常（缺血性坏死、腱鞘囊肿、黄瘤）接受了手术。根据20例有手术相关性患者的检查结果，MR成像检测TFC撕裂的准确性为95%。MR成像是研究TFC病理状况的一种有价值的非侵入性方法。
