摘　　要：目的观察增强MRI和全身骨显像间隔时间对骨显像时肝脾摄取99mTc-MDP的影响。方法回顾性分析3268例全身骨显像患者的资料,通过PACS系统追访骨显像前接受增强MRI、骨显像时肝脾摄取99mTc-MDP的患者例数,根据增强MRI与全身骨显像的间隔时间将其分为间隔0、1、2、3天组,根据肝脾摄取情况分为肝摄取组、脾摄取组和肝脾摄取组。结果 63例患者骨显像前接受增强MRI,其中42例存在99mTc-MDP肝脾摄取。间隔0、1天组肝脾摄取99mTc-MDP例数最多,共计35例(35/42,83.33%)。42例中,单纯肝脏摄取26例,占61.90%(26/42),单纯脾脏摄取1例,占2.38%(1/42),肝脾同时摄取15例,占35.71%(15/42)。结论增强MRI与全身骨显像间隔时间对骨显像时肝脾摄取99mTc-MDP有直接影响,建议两种检查间隔3天以上。Objective To explore the impact of the interval time between enhanced MRI and whole body bone imaging on hepatic and splenic uptake of 99mTc-MDP. Methods A total of 3268 patients underwent whole body bone imaging were ret- rospective analyzed. The number of patients who were tested by enhanced MRI prior to bone imaging through PACS system and had hepatic and splenic uptake of 99mTc-MDP were counted. According to the different interval time between enhanced MRI and whole body bone imaging, the patients were divided into 0 day group, 1 day group, 2 days group and 3 days group while according to uptake, they were divided into hepatic uptake group, splenic uptake group, as well as hepatic and splenic uptake group. Results There were 63 patients underwent enhanced MRI prior to bone scan, 42 patients with hepaffc and/or splenic uptake of 99mTc-MDP. There were totally 35 patients in 0 day and 1 day group, accounting for 83.33% （35/42）. There were 26 patients in hepatic uptake group （26/42, 61.90%）, while was 1 （1/42, 2.38%） in splenic uptake group and 15 in hepatic and splenic uptake group （15/42, 35.71%）. Conclusion The time interval between enhanced MRI and bone imaging has directly impact on the l;tiffuse hepatic and splenic uptake of 99mTc-MDP. It is suggested that the scanning interval time should be at least 3 days.
