From: The role of dynamic contrast-enhanced CT in characterization of solitary solid pulmonary nodules
Dynamic CE-CT study A Pre-contrast axial CT scan of the chest on mediastinal window, B–F contrast-enhanced axial CT scans of the chest on mediastinal window obtained 1,2,3,4 &15 min, respectively, after contrast injection: All figures showed well-defined pulmonary nodule with regular margin in right lower lung lobe measured 1.2 cm shows mean pre-contrast enhancement of 43 HU, mean peak enhancement (after 2 min) of 102 HU and net enhancement of 59 HU. G Axial CT scan of chest in pulmonary window showing the same pulmonary nodule with regular borders in right lower lung lobe. Pathological diagnosis: Metastatic nodule from ovarian carcinoma
