摘要目的比较18F-脱氧葡萄糖(FDG)和18F-氟胸腺嘧啶(FLT)PET/CT检查对乏脂肪肾上腺肿瘤良恶性的鉴别有无差异。方法将40例病人纳入检查组,其中包括30例乏脂肪的良性肿瘤,11例恶性肿瘤。FDG和FLT的观察指标包括目测评分,最大标准摄取值(SUV_(max))和肾上腺病灶/肝脏FDG SUVmax比值(A/L SUV_(max))或肾上腺病灶/背部肌肉FLT SUVmax比值(A/B SUV_(max)),使用U检验或T检验来比较良恶性肿瘤中这些指标的差异性。诊断效能通过病人的手术特征分析算 Abstract Objective To compare the differences between benign and malignant adrenal tumors with 18F-deoxyglucose (FDG) and 18F-fluorothymidine (FLT) PET / CT. Methods Forty patients were enrolled in the study group, including 30 cases of benign tumors lacking fat and 11 cases of malignant tumors. FDG and FLT included visual acuity, maximum standard uptake (SUV max) and adrenal / liver FDG SUVmax (A / L SUV max) or adrenal / back FLT SUVmax (A / B SUV max), U-test or T-test was used to compare the differences between these indicators in benign and malignant tumors. Diagnostic performance is calculated by the patient’s surgical characteristics
