摘　　要：目的探讨通过注意骨显像的技术操作要点及正确使用骨显像的各种方式提高骨显像影像质量的方法。方法对本科2011年～2012年2543例接受骨显像检查的患者进行分析。显像仪器为GE公司生产的Infinia VC Hawk-eye双探头带符合线路SPECT,配低能通用型准直器。全身骨显像、局部骨显像、SPECT/CT骨显像静脉注入显像剂,注射后嘱患者饮水500～1 000ml,于3～4h后开始检查;三时相骨显像采用"弹丸"式静脉注射显像剂,于即刻、10min、3～4h分别采集血流相、血池相和延迟相。结果 2543例接受骨显像检查的患者,行全身骨显像2543例(100%),行三时相骨显像366(14.4%),行局部骨显像168例(6.6%),行SPECT/CT骨显像81例(3.2%)。结论技师可通过熟练掌握不同方式骨显像的操作技术及其适应症,并充分利用核医学全身显像、局部显像等各种显像方式的优势来提高骨显像影像质量。Objective To investigate methods for improving the quality of bone scan imaging through operational technical points and proper pattern of bone Imaging. Methods Bone scans of 2 543 patients during 2011-2012 were reviewed. Imaging instrument was the GE Infinia VC Hawkeye dual-detect coincidence SPECT/CT, with low energy universal collimator. Bone Imaging agent was injected intravenously in whole body bone imaging, local bone imaging, and SPECT/CT imaging. Patients were asked to drink 500-1 000 ml water after injection, and accepted examination in 3-4 hours. Pellet injection was used in three-phase bone scan, blood flow imaging, blood pool imaging and late imaging were taken immediately, and 3-4 hours respectively. Results 2 543 patients received bone scan. 2 543 cases were taken whole body bone Imaging （100%）, 366 cases were taken three phase bone Imaging （14.4%）, 168 cases were taken local bone Imaging （6.6%）, 81 cases were taken SPECT/CT （3.2%）. Conclusion Technicians can impove the quality of bone scan Imaging by being familiar with technology of all pattern bone scintigraphy and its indications, and making use of advance for whole body imaging, local imaging and other else modes.
