摘要
目的 评价MRI在严重急性呼吸综合征 (SARS)患者骨坏死随访中的作用。方法 对 2 1位SARS康复出院 3个月左右的患者行双髋MRI检查。对MRI发现异常者行CT及X线检查。结果 2 1例受检者中 ,共 6例 (2 8.6 % )、11个股骨头发现异常 (双侧 5例、单侧 1例 )。均为女性 ,平均年龄 2 9.7岁 ,平均激素用量 382 3mg。其MRI表现均符合Ficat早期 (<Ⅱ期 )股骨头缺血坏死表现。但 5例患者的CT及 6例X线平片均未见明显异常。结论 对于应用激素治疗的SARS患者 ,其随访时用MRI探查有无股骨头缺血坏死是非常必要的。
Objective To evaluate the significance of MRI in the following up of the osteonecrosis in SARS patients. Methods MRI images were obtained of the SARS patients within 3 months from the administration of corticosteroid. Additional CT and X-ray films were obtained if any abnormal signs were detected on MRI. Results 6(28.6%) of the 21 patients were found abnormal signals, the number of involved femoral head was 11(5 bilateral and 1 unilateral). All of the victims were women, average aged 29.7. The average dosage of the corticosteroid was 3823mg. In MR images, the appearances accorded to early stage of the avascular necrosis of femoral head (less than Ficat stage Ⅱ). But none of them had positive signs in the CT and X-ray films. Conclusion MRI is useful in the following up of the osteonecrosis in SARS patiens.
