Abstract
In patients with suspected solitary pulmonary nodule, early diagnosis is mandatory, in order to choose the appropriate therapeutic management Advances in MDCT and post processing software have driven the evolution of solitary pulmonary nodule imaging. Indications for imaging now include evaluation of normal anatomy and variants for surgical planning, identification, and determination of the etiology of solitary pulmonary nodule, assessment of lungs, and staging of malignant solitary nodule. The aim of this study is to evaluate the role of MDCT in differentiation between benign and malignant solitary pulmonary nodule. This study was performed at Radio diagnosis and Medical Imaging Department of Tanta University Hospital and Tanta Insurance Hospital on thirty patients with clinical and laboratory signs of solitary pulmonary nodule. Their age ranged from 45 to 72 years with 16 channels CT using IV contrast protocol. The obtained results were compared to the results of histopathological and operative data in patients who underwent surgery. MDCT showed high sensitivity in detecting the cause of solitary pulmonary nodule. MDCT of chest with contrast (our protocol in the present study) was important in diagnosis of benign and malignant solitary pulmonary nodule by characterization of the lesion according to enhancement pattern and certain CT characteristics such as calcification, cavitation, nodule attenuation, fat content and margin of the nodule.
