本研究的目的是比较数字和模拟PET/CT系统之间的肿瘤patients.Materials和methods 100例肿瘤患者（62名男性，38名女性;平均年龄为6512岁）的图像质量和病变检测能力从2018年1月至6月前瞻性纳入。所有接受两种系统扫描的患者均连续接受一天双成像方案（数字和模拟PET/CT）。三名核医学医师使用4分量表（-1，差; 0，一般; 1，好; 2，优秀）评价图像质量，并通过计数放射性示踪剂摄取增加的病变数量来评价检测能力。对于p值，认为差异具有显著性
ObjectiveThe purpose of this study was to compare image quality and lesion detection capability between a digital and an analog PET/CT system in oncological patients.Materials and methodsOne hundred oncological patients (62 men, 38 women; mean age of 6512years) were prospectively included from January-June 2018. All patients, who accepted to be scanned by two systems, consecutively underwent a single day, dual imaging protocol (digital and analog PET/CT). Three nuclear medicine physicians evaluated image quality using a 4-point scale (-1, poor; 0, fair; 1, good; 2, excellent) and detection capability by counting the number of lesions with increased radiotracer uptake. Differences were considered significant for a p value
