| 目的 探讨时间飞行（TOF）技术PET/CT和PET/MR检查体部恶性病变SUVmax值的一致性。方法 回顾性分析接受TOF-PET/CT和TOF-PET/MR检查的体部恶性肿瘤患者20例，分为先PET/CT后PET/MR组和先PET/MR后PET/CT组，每组10例。采用Bland-Altman图评价两次检查病灶SUVmax值的一致性，采用多因素方差分析评价扫描顺序和机器类型对病灶的SUVmax测量值的影响。结果 TOF-PET/CT与TOF-PET/MR检查病灶的SUVmax值有较好的一致性 。扫描顺序对于恶性病灶的SUVmax有影响（F=46.00，P<0.001），而机器类型对恶性病灶的SUVmax值无影响（F=0.005，P=0.95）。结论 TOF-PET/MR和TOF-PET/CT在体部恶性病变SUVmax值测量方面具有相当的诊断价值，且延迟显像SUVmax的增加与采集时间有关，而与检查机器类型无关。 |

| Objective To explore the consistency of time-of-flight (TOF) technology of PET/MRI and PET/CT for max standardized uptake value (SUVmax) of body malignant tumors. Methods A retrospective analysis of TOF-PET/CT and TOF-PET/MR imaging data about twenty patients with body malignant tumors was performed. Patients were divided into two groups (each n=10), including PET/CT first and sequentially PET/MR group and PET/MR first and sequentially PET/CT group. Bland-Altman figure was used to evaluate consistency of SUVmax of malignant lesions between TOF-PET/CT and TOF-PET/MR. Multi-way ANOVA was used to analysis effect of machine type and exam order on SUVmax of malignant lesions in TOF-PET/CT and TOF-PET/MR. Results SUVmax of malignant lesions in TOF-PET/CT and TOF-PET/MR had good consistency in two groups (PET/CT first and sequentially PET/MR group: Mean difference was 3.06, 95%CI was ; PET/MR first and sequentially PET/CT group: Mean difference was 3.0, 95%CI was). SUVmax was not influenced by machine type (F=0.005, P=0.95), but exam order (F=46.00, P<0.001). Conclusion PET/MR and PET/CT with TOF technology have comparative diagnostic value in SUVmax of body malignant lesions. SUVmax of body malignant lesions increases in delay time, which is not related to machine type, but exam time. |
