摘　　要：目的：研究应用 99mTc－ MDP ECT显像技术诊断试验高压电损伤的损伤程度。方法： 15只兔，用高压电造成轻、重和毁损三种损伤模型，伤肢分别进行 99mTc－ MDP三相显像、解剖探察和组织学观察。结果：轻度击伤肢血流相及血池相均显示局部核素浓聚，组织学上证实为细胞轻度水肿，微血管栓塞；重度损伤，肢体远端影象淡而不清，并在近端影象骤然增强，组织学上为肌间隔性溶解碎裂，多数血管栓塞；特重毁损伤肢动脉学流灌注中断，影象的界面平整刀割样，镜下肌大片溶解坏死。结论：组织损伤程度与 99mTc－ MDP影浓淡缺失一致，与组织学和临床相符，可较准确反应不同损伤的伤情。Objective: Try to use 99mTc－ MDP ECT visualization technique for the determination of the degree of high voltage electric injury. Method: 15 rabbits were injured electrically to result in slight, severe and destructive electrical injuries in limbs. Three－ phase visualization was done in injured limbs using 99mTc－ MDP and anatomical and histological changes were observed. Results: In limbs with slight electric injury, local concentration of nuclide was found in blood stream and pool phases. The cells had slight edema and micro－ vessels were blocked. In limbs with severe injury, distal pictures were weak and not clear and proximal pictures were strengthened. Histologically, there were dissolved fragments of intermuscular spetum and most of the vessels were blocked. In limbs with especially severe injury, blood flow and perfusion was blocked in artery, the interface of the picture was flat as knife cut. Muscles were necrotic and dissolved when observed under microscope. Conclusion: Histological injury degree agrees with the degree of the clearness of the picture of 99mTc－ MDP and also agrees with the clinical data. 99mTc－ MDP visualization method can reflect the degree of the injury.
