Planar skeletal scintigraphy has become established as a standard diagnostic test performed within the nuclear medicine department. Since the 1970s good quality images have been produced using an Anger gamma camera and 99Tcm-labelled diphosphonates. Single photon emission tomography (SPET) has improved the sensitivity of detection and the ability to localize bony pathology, particularly benign bone disease in the spine. Recently multi-detector gamma cameras dedicated to SPET have become available. One such system, the Toshiba GCA-9300A, has been used to perform routine clinical skeletal SPET in 81 patients. Good quality images have been obtained using an 8 min acquisition in the axial skeleton and a 16 min acquisition protocol in the peripheral skeleton. Multiple sites can be tomographed in the same patient during the same examination using two or more 8 min acquisitions. Such a multi-detector gamma camera offers advantages over the standard single-headed rotating camera for skeletal SPET in terms of both imaging time and image quality. A cost analysis was performed which demonstrated that the additional cost of purchasing such a multidector gamma camera was less than 30.00 pounds per SPET study.
平面骨闪烁显像已成为核医学科开展的一项标准诊断检查。自20世纪70年代以来，使用安格γ相机和99锝标记的二膦酸盐可获得高质量图像。单光子发射断层扫描（SPET）提高了检测的敏感性以及定位骨病变的能力，尤其是脊柱的良性骨病。最近，专门用于SPET的多探头γ相机已可供使用。其中一个这样的系统，东芝GCA - 9300A，已用于对81例患者进行常规临床骨骼SPET检查。通过对轴向骨骼进行8分钟采集以及对外周骨骼采用16分钟采集方案，获得了高质量图像。在同一次检查中，同一患者可使用两次或更多次8分钟采集对多个部位进行断层扫描。就成像时间和图像质量而言，这种多探头γ相机在骨骼SPET方面比标准的单头旋转相机具有优势。进行了成本分析，结果表明购买这种多探头γ相机的额外成本每项SPET检查不到30.00英镑。
