    目的 研究北京永新医疗设备有限公司的NET632型SPECT与德国西门子公司的Symbia T16型SPECT/CT在全身骨骼显像中的等效性。
    方法 选取2018年3月至9月于内蒙古医科大学附属医院行Symbia T16型SPECT/CT全身骨骼显像结果为阳性病灶的患者32例，其中男性21例、女性11例，年龄（60.87±12.25）岁。32例患者均使用NET632型SPECT行全身骨骼显像。将两种仪器的显像图像采用图像评分标准进行评分，比较阳性病灶累及区域和病灶数量。
    结果 Symbia T16型SPECT/CT的图像质量评分为5分的患者有18例、4分的有14例，无3分及以下的患者；NET632型SPECT的图像质量评分为5分的患者有16例、4分的有16例，无3分及以下的患者。Symbia T16型SPECT/CT全身骨显像共发现阳性病灶累及区域数为84个，累及部位为胸部、脊柱、骨盆、四肢和颅骨，病灶数量分别为19、24、20、16、5个；NET632型SPECT在相同位置发现与其数目相等的病灶。
    结论 永新医疗的NET632型SPECT与西门子公司的Symbia T16型SPECT/CT在全身骨骼显像探测病灶方面具有等效性。

     

    Abstract:
    Objective To study the equivalence of the Novel Medical NET632 SPECT and the SIEMENS Symbia T16 SPECT/CT in whole-body bone scintigraphy.
    Methods A total of 32 cases (21 males and 11 females; aged 60.87±12.25 years) in the Department of Nuclear Medicine of the Affiliated Hospital of Inner Mongolia Medical University from March 2018 to September 2018 were found positive with bone lesions in the whole-body bone scintigraphy using the SIEMENS Symbia T16 SPECT/CT and the Novel Medical NET632 SPECT. Then, the image quality was compared using the same image scoring criteria. The positive lesion involvement area and the number of areas in each patient were determined using the two devices.
    Results The image qualities were scored 5, 4, and 3 (including < 3) for 18, 14, and 0 in the Symbia T16 SPECT/CT, and the image qualities were scored 5, 4, and 3（including < 3）for 16, 16, and 0. A total of 84 positive lesion sites were found in the chest, spine, pelvis, limbs, and skull by using the Symbia T16 SPECT/CT, and the numbers in each location were 19, 24, 20, 16, and 5, respectively. The same number of positive lesions was observed in the same locations for the NET 632 SPECT.
    Conclusion The Novel Medical NET632 SPECT and the SIEMENS Symbia T16 SPECT/CT detect the lesions in whole-body bone scintigraphy equivalently.
