Graphs 7 and 8 also illustrate diameter measurements taken in the bronchus intermedius and left main bronchus on lung window and were consistently less than measurements in soft tissue windows (ICC consistency 0.
The wide window and low-level setting of lung window should make it the desired setting for evaluating the airfilled airways.
All measurements were performed both in soft tissue window (Window 350/Level 50) and lung window (Window 1600/Level 500) settings (Figs 1C and 1D).
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.
Radiologists can configure a single viewing protocol for a CT abdomen and pelvis, for example, with their choice of a variety of different views: View 1) Soft tissue window presets, View 2) Lung window presents, 3) Bone window presents, Views 4-6) The preceding windows, but with prior studies added.
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.
Images are displayed with 3 different gray scales for interpretation of lung window (window width/level [HU] = 1500/-600), mediastinal window (350/40), and PEspecific (700/90) window settings.
Such artifacts are best recognized on lung window settings as the blurring of vessels and rapid change in the position of vessels on contiguous images (Figure 11).
High attenuation is recognizable on soft-tissue windows, but is easily missed if only lung windows are assessed.
Measurements taken in lung windows consistently measure the diameter of stenoses of the central airways less than soft tissue (1.
