False positive recognition is crucial for proper interpretation of FDG-PET studies. The authors present a case of a woman who underwent surgery over a month prior to PET/CT imaging which revealed significant tracer uptake within muscles and soft tissue in several sites contralateral to the location of surgery. The FDG-PET images of this case illustrate the importance of communication between physicians ordering and physicians reading FDG-PET/CT scans as well as atypical FDG-PET findings that could be interpreted as concerning but are, in fact, innocuous. This study also demonstrates the unusual glucose metabolic patterns which may arise following treatment be it surgical, chemotherapeutic or radiation.
假阳性识别对于正确解读FDG-PET研究至关重要。作者介绍了一名女性病例，该女性在PET/CT成像前一个多月接受了手术，PET/CT成像显示在手术部位对侧的多个部位的肌肉和软组织中有明显的示踪剂摄取。该病例的FDG-PET图像说明了订购FDG-PET/CT扫描的医生与解读扫描结果的医生之间沟通的重要性，以及可能被解读为可疑但实际上无害的非典型FDG-PET表现。这项研究还展示了无论是手术、化疗还是放疗后可能出现的异常葡萄糖代谢模式。
