| Abstract: | Purpose:This study assesses the diagnostic value of X-ray, CT and ECT onischemic necrosis of femoral head in different stages. Materials and Methods In 82 cases withischemic necrosis of femoral head in early.Middle and advanced stages, the findings in X-ray,CTand ECT examinations were studied with retrospective analysis. Results No early findings werecharacteristic and the lesions less than 0.3cm might be missed in X-ray films. The CT scans inearly diagnosis were superior to the radiograms. However, ECT examinations showed theradioactive defective "cold area", even at the first several weeks after onset. Conclusions: for earlylesions ACT are the most ideal examinations method. X-ray helps to distinguish the type of lesionsin middle and late stages. CT in the characteristics and anatomical resolution of lesions is clearlysuperior to ECT and it may give a reliable judgement for the size, shape, site and extent of lesions,which helps to guide and locate operation. |
