Many musculoskeletal conditions have in the past been best defined on a clinical basis. However, because of pain, limitation of motion and hematomas, tendon ruptures can often be misdiagnosed clinically and it would be quite helpful to the clinician to have a noninvasive imaging technique. This communication defines the role of MRI in the early diagnosis of a nontraumatic rupture of the quadriceps tendons bilaterally in a patient with renal failure and known secondary hyperparathyroidism. The imaging techniques accurately defined the presence of hemorrhage extending into muscle from the ruptured tendons as well as the actual site and extent of tendon rupture. Since tendons have low mobile proton content and have low signal on MRI--disruptions are easily seen--MRI is the ideal noninvasive imaging technique for tendon injury, acute.
过去，许多肌肉骨骼疾病最好在临床基础上进行诊断。然而，由于疼痛、活动受限和血肿，肌腱断裂在临床上常常被误诊，因此拥有一种非侵入性成像技术对临床医生会有很大帮助。本文阐述了MRI在一名肾衰竭且患有继发性甲状旁腺功能亢进患者双侧股四头肌肌腱非创伤性断裂早期诊断中的作用。成像技术准确地确定了从断裂肌腱延伸至肌肉的出血情况以及肌腱断裂的实际部位和范围。由于肌腱中可移动质子含量低，在MRI上信号较弱，断裂很容易被发现，所以MRI是诊断急性肌腱损伤的理想非侵入性成像技术。
