In CT imaging, what does the window width (WW) and window level (WL) setting of 1500 and 700, respectively, indicate?
Adjustment for bone imaging
Optimization for lung imaging
Standard parameters for brain CT scans
Default settings for abdominal scans
What parameter should be adjusted to reduce radiation exposure for long-term monitoring of TB patients?
Window settings
kVp and mAs settings
kVp and mAs settings
Scan area
What is a common imaging characteristic of bronchiectasis?
Pleural thickening
Cavitations and nodular lesions
Bronchial dilation and airway wall thickening
Ground-glass opacity and centrilobular nodules
What is the typical scan area for a CT thorax?
From the diaphragm to the clavicle
From the neck to the lower abdomen
From above the lung apices to below the costophrenic angle
From the trachea to the heart apex
What is one method to improve CT imaging for patients who cannot hold their breath?
Use ultra-fast helical acquisition
Increase kVp and mAs settings
Switch to a larger field of view (FOV)
Perform repeated scans for clarity
