Breast Lesion in CT Chest

Enhanced chest CT examination reports containing the key word 'breast' well be reviewed retrospectively. Patients who had incidental breast lesion and were referred to a specialized breast unit and then underwent pathological confirmation well be included. Finally, 100 patients well be enrolled. Two radiologists well evaluate lesion characteristics including; size, shape, margins and enhancement. The correlations between the CT features and pathologies well be evaluated and the diagnostic accuracy of CT features in various combinations well be assessed.
