RTBC A+ EXAM 24: LATEST VERSION ENGAGING
QUESTIONS AND ANSWERS (100% ACCURATE)
WL increases what happens to brightness
brightness decreases
- lowest WL with have brightest image
during CTA of the chest what landmark is used to identify the level of pulmonary
arteries?
carina- level of pulmonary trunk and arteries.
where is the carina
base of the trachea where the trachea bifurcates into left and right main stem bronchi
area of itnerest for chest wall ct is
ribs and muscle around lungs
advantage of using mpr in ct
MPR uses any plane
primary indication for using contract for soft tissue neck
to differentiate between tissue types
fluid around the heart
pericardial effusion
ring artifact can be caused by
non uniform detector
contrast on the detector
which dfov corresponds to highest spatial resolution
smallest dfov = highest spatial res
xray frequency and wavelength relationship
inversely proportional
venous phase delay
40 seconds
soft tissue pathology of the chest use what delay
40 sec venous
name th pathology
