摘要
成人股骨头缺血性坏死(FHAVN)的影像学诊断方法包括X线片、CT、磁共振成像(MRI)和核医学。X线片检查可作为首选的方法,但在疾病的早期缺乏敏感性,而MRI更具备优势。MRI被认为是诊断疾病早期改变的"金标准",也可用于指导治疗和患者的随访。CT用于描述晚期的变形以及减少MRI在诊断软骨下骨折的检阳性结果。核医学成像和先进的核磁共振技术在成人FHAVN的应用方面仍有待进一步证实。
Radiological diagnosis methods of adult femoral head avascular necrosis（ FHAVN） include X-ray,CT,magnetic resonance imaging（ MRI）,and nuclear medicine. X-ray examination is the first line approach,but lacks of sensitivity in early stage whereas MRI has more advantages. MRI is unanimously considered the gold standard technique in the early stages. It may also be useful to guide treatment and it is a validated technique in follow-up of patients with FHAVN. CT easily depicts late stage deformation and may decrease MRI false positive results in detecting the subchondral fracture. However,the role of both nuclear medicine imaging and advanced magnetic resonance techniques in FHAVN still need to be further validated.
