The method to doubts using multilayered spiral CT has the bone necrosis 58 examples to carry on the scanning. Finally: In 52 examples patients discovered 81 bones appear lack the blood necrosis, in the necrosis stock bone display for the irregular shape bone density do not advance the shade, bone young Liang increase the thick distortion, in 55 stocks bones appears the pouch to change, 24 stocks bones disruption distorts, 34 stocks bones merge joint cavity inner product fluid. Conclusion: The CT resolution is high, it lacks in the blood necrosis in the diagnosis stock bone to have the important value, has a bigger superiority compared to traditional X. ? 　　【key word】 stock bone; Lacks the blood necrosis; Computer fault imagery 　　 　　股骨头缺血坏死临床较为见，近年来呈逐渐增多趋势。病因及发病机理尚不十分明确。如果病变发现较晚或治疗不当，最终可导致股骨头碎裂变形和髋关节功能障碍。为了更好地在临床早期诊治本病，最大限度地保存关节功能，现总结52例股骨头缺血坏死的CT表现及其相关鉴别诊断如下。? 　　 　　1 资料与方法? 　　 　　 一般资料：本组共52例患者，男39例，女12例；年龄19～72岁，平均
