An 89-year-old man with a history of lung cancer surgery underwent a positron emission tomography-computed tomography (PET/CT) scan for suspected recurrence. The patient agreed to a six-hour fast before the scan. The PET/CT scan showed extensive accumulation in the skeletal muscles throughout the body. A large amount of content was found in his stomach. Despite his claim to have fasted before the scan, the patient seemed to have eaten. Eating before a PET/CT scan will significantly impair image quality. Fasting is essential before the procedure.
一名有肺癌手术史的89岁男性因疑似复发接受了正电子发射断层扫描-计算机断层扫描（PET/CT）。患者同意在扫描前禁食6小时。PET/CT扫描显示全身骨骼肌有广泛的放射性聚集。在他的胃里发现了大量的食物。尽管患者声称在扫描前已禁食，但他似乎进食了。PET/CT扫描前进食会显著影响图像质量。扫描前禁食至关重要。
