骨扫描（ECT）在儿童骨髓炎早期诊断中的应用
发布时间：2020-07-25 11:10
【摘要】： 目的:通过对比各种影像学诊断方法在儿童急性血源性骨髓炎早期诊断时间上的差异,提出同位素骨扫描的优点。 方法:在近6年住院的儿童急性骨髓炎61例(64部位)确诊病例中,对其中12例常规B超及X线尚未发现明显阳性改变者,行同位素骨扫描检查,阳性结果出现后,7例行骨钻孔引流或开窗减压,术后抗感染治疗2周以上。部分病例随访1年以上。综合病例资料,分别按各检查出现阳性结果的时间以例数和时间列表,对数据进行计数和计量统计分析比较。 结果:采用骨扫描诊断病例阳性结果出现时间较X线平片和B超早,早期诊断处理的患儿出现严重并发症及后遗畸形的可能性大大降低。 结论:应用骨扫描早期诊断儿童骨髓炎灵敏度较X线平片和B超高。早期诊断处理的患儿预后较好。

There is a significantincrease of radioactivity in the metaphysisof right lower femur and upper tibia图 3：三相骨扫描延迟相（骨静态显像）：前位及后位图，可见左股骨下端骨骺及干骺端、右胫骨上端骨骺放射性明显较对侧增强，左股骨中下段放射性较对侧减弱，提示该处亦受累，尚处早期Fig3：Bone static imaging: anterior and posteriorfiguration. There is a significant increase ofradioactivity in the metaphysic of left lower femurand upper tibia, however a decrease of radioactivityin the middle and lower left femur, which suggestthis part is also involved and it happened recently

图 2：三相骨扫描血流相、血池相及延迟相局部放射性活度定性及定量以及左右侧时间放射曲线对比。血池相左右放射性活度比值为 0.27；延迟相左右放射性活度比值为 0.26。可见个时相患侧股骨远端放射性活度均较健侧明显增高。Fig2: Three phases bone scanning, perfusion phase, blood pool phase and delayed phase. Anthe time activity curve of both left and right legs. Blood pool radioactive ratio is 0.27; skeletaradioactive ratio is 0.26. In all three phases there is a significant increase of radioactivity in tright lower femur
