background: computed tomography (ct) scan is one the most useful devices in chest imaging. ct scan can be used in mediastinal abnormality, lungs, and pleural evaluations. according to the high prevalence and different causes of pulmonary nodules, we designed this study to evaluate the prevalence and the types of pulmonary nodules in noncancerous patients who underwent chest multi-detector ct (m...

OBJECTIVE To review the radiological management of a solitary pulmonary nodule. DATA SOURCES MEDLINE literature search (1958-2002). STUDY SELECTION All review articles and original articles. Key words for the literature search were 'solitary pulmonary nodule' and 'imaging'. DATA EXTRACTION All relevant information and data. DATA SYNTHESIS The solitary pulmonary nodule remains a perennia...

The solitary pulmonary nodule is a challenging clinical problem. Steele (1964) reviewed 887 resected solitary nodules and found 53% granulomas, 36% malignant tumours, and 8% haematomas. This is by no means a complete list of all the causes of solitary pulmonary nodules but encompasses the vast majority of them. We have recently evaluated a patient with a nodule that had slowly enlarged over a p...

Due to the high etiological diversity and the potential for malignancy, pulmonary nodules represent a clinical challenge, becoming increasingly frequent as the number of CT examinations rises. The topic gains even more importance as clear evidence for the effectiveness of CT screening was provided by the National Lung Screening Trial (NLST). Yet, the results were tempered by the high false-posi...

The radiologic evaluation of the solitary pulmonary nodule (SPN) is a common diagnostic dilemma. Although available clinical data and findings on conventional radiographs are important components in determining the imaging approach to the SPN, evaluation with CT often is necessary for detailed evaluation. This article reviews the radiologist's approach to the evaluation of the SPN, with a parti...
