SARS患者的核素骨显像探讨

Analysis of nuclear bone scan of SARS patients

目的SARS对人体的损害是多系统和多脏器的,本文试图探讨核医学影像技术在SARS患者骨关节损伤中的作用。方法我院收治的SARS患者13例,其中男7例,女6例。将探头对准两侧股骨头区域进行骨三相显像,断层显像以及延迟的全身骨显像,观察股骨头及全身骨组织受损情况。结果骨断层相的病变检出率明显高于骨三相显像,有6例患者股骨头有损害表现,其中男3例,女3例,没有性别差异。有3例患者合并有膝和/或踝关节受损。1例患者治疗前后对照,似有好转的趋势。结论核医学影像可以在SARS的骨损害的诊断和疗效观察中起到非常重要的作用。

Objective SARS is a new disease harmful to systems and organs of human. We try to detect the damage to the bone by the image of nuclear medicine. Methods 13 SARS, spatients, 7 were males, 5 females, With feeling something wrong in his or her hip. Put the detector above the hips of the patients, the dynamic image was acquired as soon as the bolus of Tc^-99m-MDP injected. The three phase skeletal scintigraphy, the blood flow, blood pool, delayed local image, total body scab and bone SPECT was acquired. Results The bone SPECT was roueh sensitive than the three phase skeletal scintigraphy. There were locally increase or decrease on the femoral head in 6 patients, 3 males and 3 females, showed there was no diffrence between the sexes. There were locally increase on the knees and ankles in 3 patients. Among them, 1 man showed the damage turned better compared with the baseline. Conclusion Nuclear medicine image might played an important role in the diagnosis of bone
