Abnormal femoral head activity in Legg-Calve-Perthes' disease has been measured using 99Tcm -polyphosphate and a gamma camera/computer data collection system. A reference point on the data matrix, which is unaffected by the diease, is used for deriving comparative uptake ratios in each femoral head. The reference point remains unaltered after surgical procedures or short intervals between follow-up studies. Early abnormality can be measured in both unilateral and bilateral femoral head pathology.
利用99锝-多聚磷酸盐和γ相机/计算机数据采集系统对Legg-Calve-Perthes病中股骨头的异常活动进行了测量。数据矩阵上不受疾病影响的一个参考点，用于得出每个股骨头的比较摄取率。该参考点在手术操作后或随访研究之间的短时间间隔内保持不变。早期异常可在单侧和双侧股骨头病变中检测到。
