CT Thorax lung window
showing a smaller right lung with no evidence of minor and major fissure and dextroposed heart and engorged pulmonary vasculature
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.
Consistent lung window
with a mean of 600 to 700 HU and a width of about 1000-1500 HU was used.
1 & 2: Axial CT lung window
showing cystic dilatation of bronchi with thickened wall suggestive of bronchiectasis distributed predominantly in bilateral upper lobes and right middle & lower lobes.
2(c): CT chest coronal image, Lung Window
- Calcified densities in paratracheal, tracheobronchial, carinal, & hilar regions (arrows) in relation to airways clearly depicted.
Figure 6: CT Thorax showing lung cyst- (A) Lung window
(B) Aortopulmonary window.
An axial CT image through the pelvis (in a lung window
display) revealed the presence of multiple air-filled cystic areas arising from the inner wall of the sigmoid colon and protruding into the bowel lumen.
