Objective To evaluate the value of PET-CT in the diagnosis of peripheral lung cancer.
Methods The morphologic characteristics and standardized uptake value (SUV) of 70 patients with lung cancer proved by pathology were analyzed retrospectively.
Results Of the 70 cases, 32 cases were squamous carcinoma, 25 cases were adenocarcinoma, 8 cases were small cell lung cancer, 3 cases were adenosquamous carcinoma and 2 cases were megacell lung cancer.The average SUV of the lung cancer was 4.94±1.53.In the group of lung cancer, hypermetabolic lesions were found in 66 cases and the SUV was more than 2.5 while the SUV was less than 2.5 in 4 cases.Positive correlation was showed in the SUV and the size of tumors.
Conclusions The peripheral lung cancer has its special imaging appearances of PET-CT.PET-CT is an excellent modality in the diagnosis and differential diagnosis of peripheral lung cancer.The SUV combining with morphological findings sometimes may be helpful for the differential diagnosis.
