Abstract:
Objective To explore the value of 18F-fluorodeoxyglucose（18F-FDG）PET-CT and CT in diagnosing bronchioloalveolar carcinoma （BAC）.Methods The PET-CT and CT findings of 15 patients with BAC pathologically confirmed were retrospectively analyzed.Results According to 18F-FDG PET-CT,there was definite diagnosis of malignant in 8 cases（53.3 %）,no exclusion of malignancies in 2 cases （13.3%）,definite diagnosis of benign tumors in 5 cases（33.3%）.The misdiagnosis rate of 18F-FDG PET-CT is higher.According to CT,there was definite diagnosis of malignant tumors in 11 cases（73.3 %）,no exclusion of malignancies in 2 cases（13.3%）,definite diagnosis of benign tumors in 2 cases（13.3%）.Conclusion The false negative rate and the misdiagnosis rate are high when SUVmax as 2.5 was employed as criteria in the diagnosis of BAC.To improve diagnosis accuracy and decrease misdiagnosis of BAC,we should be familiar with the CT images of different BACs and adjust the SUVmax as a diagnosis value.
