摘要
18F-FDG PET显像在临床上发挥着越来越重要的作用,但其在某些肿瘤的应用中存在一定的弊端,易产生假阳性和假阴性.脂肪酸代谢PET显像在脂类代谢显像中占有非常重要的地位,在一定程度上可弥补糖代谢的不足,能提高对肿瘤诊断的灵敏度和准确率.笔者就目前应用于临床前和临床研究中的肿瘤短链脂肪酸代谢PET显像剂进行综述.
18F-FDG PET plays an increasingly important role in clinical assessment. However, some false-positive and false-negative results for certain tumors have been achieved with 18F-FDG. Furthermore, fatty acid metabolic imaging is valuable in lipid-metabolism PET imaging. This technique compensates for the deficiency of 18F-FDG PET examination and improves the diagnostic sensitivity and accuracy of tumor detection. This review provides an overview of recent developments in the use of short-chain fatty acid radioactive probes in PET imaging.
