We present the case of a patient with history of colon cancer, referred for the evaluation of indeterminate pulmonary nodules by F-FDG PET/CT. A dual-time point protocol was performed, and images were reconstructed using VUE Point HD and a Bayesian-penalized likelihood reconstruction algorithm (Q.Clear). Visually, the quality of the images was considered better when Q.Clear was used with β value of 200, uptake in the smallest nodule (7 mm) was clearly visible only with Q.Clear reconstruction, and uptake in the smaller nodules was best defined in the delayed time point acquisition. Quantitative parameters were also higher for Q.Clear.
我们报告了一例结肠癌病史患者，因 F-FDG PET/CT 检查发现肺部不确定结节而就诊。该患者行双时相采集方案，使用 VUE Point HD 及基于贝叶斯正则化似然的重建算法（Q.Clear）进行图像重建。从主观上看，当β值为 200 时，使用 Q.Clear 重建的图像质量更好，7mm 小的结节摄取清晰可见，而在延迟采集时较小的结节摄取显示最佳。Q.Clear 的定量参数也更高。
