OBJECTIVES
We compared the accuracy of shorter-time dual-phase (18)F-FDG PET/CT in evaluating 94 different lung nodules classified as solid or ground-glass nodules (GGNs).
MATERIALS AND METHODS
Early and delayed maximum standardized uptake values (SUV(max)) as well as the retention index (RI) of each nodule were determined in 75 solid nodules and 19 GGNs.
RESULTS
In solid nodules, early SUV(max), delayed SUV(max), and RI were higher in malignant than in benign lesions. In GGNs, these values were not significantly lower in the malignant than in the benign lesions.
CONCLUSION
In the patient group with solid nodules, shorter-time dual-phase (18)F-FDG PET/CT could significantly differentiate the malignant from the benign ones.
目的
我们比较了更短时程双时相 18F-FDG PET/CT 在评估 94 个不同肺结节（分类为实性或磨玻璃结节）中的准确性。
材料与方法
在 75 个实性结节和 19 个磨玻璃结节中，分别测定每个结节的早期和延迟期最大标准化摄取值（SUV(max)) 以及滞留指数（RI）。
结果
在实性结节中，恶性结节的早期 SUV(max)、延迟期 SUV(max)和 RI 高于良性病变。在磨玻璃结节中，恶性结节的这些值与良性病变相比没有明显降低。
结论
在实性结节患者组中，更短时程双时相 18F-FDG PET/CT 可显著区分良恶性。
