Abstract

Three cases of severe crush syndrome after the Wenchuan earthquake in China are presented．The patients．2 males and one female ranging in age fr0m 1 8 45 years were studied via 1．5 T magnetic resonance imaging（MRI）and magnetic resonance angiography（MRA）．MRI examinations were performed more than twice on two patients within 60 days of the earthquake．All the patients had acute renaI failure（ARF）with plasma myoglobin concentrations above 17000 ug／L．The T2一weighted and short time inversion recovery（STIR）sequences revealed high intensity Iesions in the affected muscles，and enhanced T1一weighted images showed enhancement of partial affected muscles．MRA revealed no signs of arteriaI occlusion，arteriostenosis，or filling defects of main arteries．All patients were managed medically with continuous venous—venous hemofiltration and other supportive care．and none required fasciotomy or amputation．Repeat MR studies showed that the high intensity Iesions seen on the T2一weighted and STIR sequences resolved in paralle1 with improvement of laboratory studies and clinical course.
