Results are reported of the use of new imaging methods, CT scan and magnetic resonance imaging, in 12 patients with algodystrophy of femoral head. During the early stages a CT scan can detect partial demineralizations, observed on MR images in sagittal sections. When the disease is installed the CT scan images show global demineralization, but the MR images with coupled T1-T2 study appear to be more pathognomonic (hyposignal extended in T1 with hypersignal in T2, associated with a more marked subchondral hyposignal in T1 as in T2) particularly in relation to the osteonecrosis of femoral head.
报告了对12例股骨头无菌性坏死患者使用新型成像方法(CT扫描和磁共振成像)的结果。在疾病早期,CT扫描可检测到部分骨质脱矿,在矢状面的磁共振图像上也可观察到。当疾病确立时,CT扫描图像显示整体骨质脱矿,但结合T1 - T2研究的磁共振图像似乎更具特征性(T1加权像上低信号延长,T2加权像上高信号,同时T1加权像和T2加权像上软骨下低信号更明显),尤其是对于股骨头缺血性坏死而言。
