作者定量评估了在原发性肺癌肿瘤中获得的非衰减校正2-[氟-18]氟-2-脱氧-d -葡萄糖（FDG）正电子发射断层扫描（PET）扫描中引入的肿瘤大小和形状可能的扭曲。通过x线计算机断层扫描（CT）、衰减校正FDG PET和非衰减校正FDG PET扫描测量21例原发性肺癌肿瘤。未衰减校正的FDG PET扫描的肿瘤正位尺寸明显大于衰减校正的FDG PET或CT扫描（P = 0.05，平均差值为28%）（P = 0.0007，平均差值为30%）。非衰减校正FDG PET扫描左至右肿瘤尺寸显著小于衰减校正FDG PET扫描（P = 0.03，平均差值8.5%），但与CT扫描无显著差异（P = 0.03）。
The authors quantitatively evaluated possible distortions of tumor size and shape introduced on non-attenuation-corrected 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) scans obtained in primary lung cancer tumors. Primary lung cancer tumors in 21 patients were measured on x-ray computed tomography (CT), attenuation-corrected FDG PET, and non-attenuation-corrected FDG PET scans. Apparent anteroposterior tumor dimensions on non-attenuation-corrected FDG PET scans were significantly larger (P = .0007; mean difference, 30%) than on attenuation-corrected FDG PET or CT scans (P = .05; mean difference, 28%). Left-to-right tumor dimensions on non-attenuation-corrected FDG PET scans were significantly smaller than on attenuation-corrected FDG PET scans (P = .03; mean difference, 8.5%) but were not significantly different from those on CT scans (P = .3).
