A CT scan was done in an attempt to see the kidney in the lung window with success - the kidney was visible this time with no signs of obstruction or stones [Figure 1]b.
The chest CT on lung window imaging showed centrilobular and paraseptal emphysematous changes in the upper lung zones and a large bulla with surrounding consolidation on the right lower lobe, which was considered as the cause of hemoptysis.
5mm reconstructed images in lung window and 3mm images in mediastinal window were viewed on workstation in axial, coronal and sagittal planes.
We wished to determine if there was a significant difference between the measurements of compressed airway diameter in the axial plane compared with measurements of diameter using MPR for determining longitudinal axis of the airway; and to evaluate how measurements on lung window settings compare with soft tissue window settings.
Figure 3 is an axial noncontrast computed tomographic image on a lung window that demonstrates a spiculated mass in the left upper lung in addition to paraseptal emphysematous changes.
