放射性核素骨显像股骨头/干比值半定量分析的临床意义

Clinical Significance of Semiquantitative Analysis of Femoral Head/Shaft Activity Ratio with Radionuclide Bone Imaging

本文总结放射性核素 SPECT 骨显像,股骨头/干比值半定量分析对股骨头无菌性坏死、骨质疏松的临床意义。16例正常成年女性的头/干比值右侧为3.89±0.54,左侧3.86±0.60,与国外报告结果近似。18例老年性骨质疏松病人头/干比值明显低于正常,而股骨头无菌性坏死头/干比值明显高于正常,与正常值比较均有显著性差异。由于放射性核素骨显像有较高的灵敏性,以股骨头/干比值做为半定量指标,对股骨头无菌性坏死及骨质疏松的诊断,疗效评价均有良好的临床意义。

Clinical significance of a semi-quantitative analysis of femoral head/shaft acti-vity ratio in femoral head aseptic necrosis and osteoporosis was summarized.Thehead/shaft activity ratio in 16 normal adult females was 3.89±0.54(right)and 3.96±0.60(left).The result was similar to that of foreign reports.Femoral head/shaft ratio of the aged osteoporosis in 18 patients was obviouslylower than normal,but obviously higher in femoral head aseptic necrosis.There wereobvious differences between patients and normal subjects.Since bone imaging with radionuclide had a considerable sensitivity,so a semi-quantitative analysis of femoral head/trunk activity ratio was of good clinical signi-ficance for diagnosis and treatnant of femoral head aseptic necrosis and osteoporosis.
