a) Axial, 5-mm slice thickness computed tomography (CT) image through the upper lobes at the level of the aortic arch. No clear lung nodules can be visualised at this axial CT image in the lung window. Only a slight irregular structure (arrow) can be retained in the right upper lobe, superimposed on a vascular structure. b) Maximum intensity projection (MIP) image through the upper lobes at the level of the aortic arch. A clear lung nodule can now be visualised (square). MIP images are better for indentifying small pulmonary nodules.
