CT and PET/CT in the diagnosis of pleural mesothelioma / 医学研究生学报

ABSTRACT

Objective:To study the CT and PET/CT features of pleural mesothelioma and the value of CT and PET/CT imaging in the diagnosis of the disease.Methods:We retrospectively analyzed the spiral CT images of 23 patients and PET/CT images of 7 patients with pleural mesothelioma,all histologically confirmed.Results:Of the 23 cases detected by spiral CT,7 were benign and 16 malignant;local nodular pleural thickening was found in 9 cases,7 benign and 2 malignant;diffuse pleural thickening was observed in 14 cases,all malignant.Of the 7 cases diagnosed by PET/CT,5 were excluded from surgery.Conclusion:CT imaging helps determine the location,shape,extent of the pleural lesion and its relation to the surrounding tissues,while PET/CT is better in the differentiation of pleural mesothelioma and staging of malignancy,and therefore plays an important guiding role in the treatment of the disease.
