Abstract:
Objective To assess the cli ni cal usefulness of dual-modality positron emission tomographic (PET)-computed t omographic (CT) imaging in pulmonary lesions. Methods Fo rty-nine patients with pulmonary lesions examined with ?~2 test. Results There were 50 primary lesions in 49 patients. Accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predict ive value (NPV) were 90.0%, 95.2%, 62.5%, 93.0%, and 71.4%, respectively wi th PET-CT, 74.0%, 76.2%, 62.5%, 91.4%, and 33.3%, respectively with CT. There was significant differences between them (P0.05). Conclusion PET-C T has an important clinical value in differentiating benign lesion from malignan cy and staging in lung cancer.
