| 目的 对比以国产NeuWise及Philips Ingenuity TF PET/CT仪所获18F-FDG全身显像图像质量及其半定量参数。方法 纳入34例于同日分别接受以NeuWise和Philips Ingenuity TF PET/CT仪进行的全身18F-FDG PET/CT检查患者,比较2种图像质量评分及其半定量参数,包括正常组织平均标准摄取值(SUVmean)、病灶最大标准摄取值(SUVmax)、峰值标准摄取值(SUVpeak)、SUVmean、病灶糖酵解总量(TLG)及肿瘤代谢体积(MTV)。结果 2种图像质量及病灶半定量参数差异均无统计学意义(P均＞0.05),而主动脉弓、肝脏、腰椎及脊髓SUVmean差异均有统计学意义(P均＜0.05)。2种图像之间病灶SUVmax、SUVmean、MTV及TLG均呈强相关(rs=0.734~0.890,P＜0.001),SUVpeak呈高度相关(r=0.919,P＜0.001),病灶SUVmax、SUVpeak、SUVmean、TLG及MTV一致性较好至极好(ICC=0.891~0.986,P均＜0.001),且全部半定量参数差值均在95%置信区间内。结论 以国产NeuWise与Philips Ingenuity TF PET/CT仪所获18F-FDG全身显像图像质量均能满足临床诊疗要求,且基于2种图像所获半定量参数具有良好一致性。 |

| Objective To compare imaging quality and semi-quantitative parameters of 18F-FDG whole-body images obtained with domestic NeuWise and Philips Ingenuity TF PET/CT scanners. Methods Thirty-four patients who underwent 18F-FDG whole-body scanning using NeuWise and Philips Ingenuity TF PET/CT systems respectively on the same day were enrolled. The imaging quality and semi-quantitative parameters of 2 kind images, also the mean standard uptake value (SUVmean) of normal tissue, the maximum standard uptake value (SUVmax), peak standard uptake value (SUVpeak), SUVmean of lesions, total lesion glycolysis (TLG) and metabolic tumor volume (MTV) were compared. Results No significant difference of imaging quality nor semi-quantitative parameters of lesions (all P＞0.05), while significant differences of SUVmean of aortic arch, liver, lumbar vertebra and spinal cord were found between 2 kind images (all P＜0.05). Strong correlations of SUVmax, SUVmean, MTV and TLG of lesions (rs=0.734—0.890, P＜0.001), and high correlation of SUVpeak (rs=0.919, P＜0.001) were found between 2 kind images. The consistency of SUVmax, SUVpeak, SUVmean, TLG and MTV at the lesion site between 2 kind images were very good to extremely good (ICC=0.891—0.986, all P＜0.001), and the differences of all above semi-quantitative parameters were within 95% confidence interval. Conclusion Imaging quality of 18F-FDG whole-body images obtained with domestic NeuWise and Philips Ingenuity TF PET/CT scanners could meet the requirements of clinical diagnosis and treatment, and semi-quantitative parameters obtained based on both images had good consistencies. |
