骨梗死的MRI诊断6例报告

The report of 6 cases MRI diagnosis of bone infarction

目的分析骨梗死的MRI表现,探讨骨梗死在不同时期的病理变化。方法回顾性分析我院2011年至今6例骨梗死患者的MRI检查情况。结果 6例患者共累及15个部位,其中股骨下端8个,胫骨上端6个,肱骨上端1个。结论骨梗死多表现为多发性、对称性,好发于四肢长骨,多见于股骨下段、胫骨上段和肱骨上端。磁共振成像(MRI)检查是早期诊断骨梗死最有效的方法,能够了解骨梗死不同时期的病理变化,其特征性表现对早期诊断有帮助。

Objective To analyze the pathological changes of bone infarction in different stages and the corresponding MRI features,and to explore the application value of MRI in the diagnosis of bone infarction. Methods 6 cases of bone infarction patients in our hospital from 2011 to 2016 were collected, a 11 of which？were examined by MRI. Results 15 lesions were found in 6 patients.There were 8 lesions on distal segment of femur, 6 lesions on proximal segment of tibia, and 1 lesions on proximal segment of hum e r us.Conclusion Bone infarction often manifested as multiple and symmetrical,occurs in the extremities,common in the distal femur,proximal tibia and proximal.Hu merus MRImanifestation of bone infarction has characteristics.MRI can be used in the early diagnosis.
