MR imaging of the kidney was performed in 6 patients with acute renal failure (ARF) secondary to rhabdomyolysis caused by snake bite (n = 4), crush injury (n = 1), and carbon monoxide poisoning (n = 1). A test for urine myoglobin was positive in all 6 patients and MR imaging was done 6 to 18 days after the causative event of the rhabdomyolysis. MR images in all 6 patients showed globular swelling of the kidneys, preserved corticomedullary contrast on T1-weighted images, and obliteration of corticomedullary contrast on T2-weighted images. Unlike other medical renal diseases in which corticomedullary contrast is lost on T1-weighted images, preservation of the corticomedullary contrast on T1-weighted MR images with globular renal swelling was a constant finding in patients with ARF secondary to rhabdomyolysis.
对6例因蛇咬伤（n = 4）、挤压伤（n = 1）和一氧化碳中毒（n = 1）导致横纹肌溶解继发急性肾衰竭（ARF）的患者进行了肾脏磁共振成像（MR成像）检查。所有6例患者的尿肌红蛋白检测均呈阳性，且在横纹肌溶解致病事件发生6至18天后进行了MR成像检查。所有6例患者的MR图像均显示肾脏呈球状肿大，T1加权图像上肾皮质髓质对比度保留，T2加权图像上肾皮质髓质对比度消失。与其他医学肾脏疾病不同，在T1加权图像上肾皮质髓质对比度丧失，而在继发于横纹肌溶解的ARF患者中，T1加权MR图像上肾皮质髓质对比度保留且肾脏呈球状肿大是一个持续存在的表现。
