Osteochondroma
After taking a radiograph using 300 mA, 0.043 sec, 80 kVp, you notice the image is underexposed and diagnostically of little value. In order to get a noticeable improvement in image quality, your next exposure should be taken at:
a. 150 mA, 0.043 sec, 92 kVp
b. 400 mA, 0.05 sec, 80 kVp
c. 300 mA, 0.043 sec, 68 kVp
d. 500 mA, 26 ms, 82 kVp
b. 400 mA, 0.05 sec, 80 kVp
A patient with a small bronchopneumonia has developed a large pneumothorax. The correct selection of exposure factors would require:
A decrease in exposure technique
An increase of _______ will compensate for most additive pathological conditions.
5-15% in kVp
When healthy lung tissue becomes fibrotic such as in the condition of pnuemoconiosis,
a. Tissue density increases
b. An increase in exposure technique may be necessary
c. An additive condition is present
d. All of the above
d. All of the above
Most destructive conditions should require a reduction in _____ to compensate for the tissue condition.
mAs
Newborn babies typically swallow large amounts of air as they cry. This presents a condition of _____ and would require a/an _______ in exposure technique.
Aerophagia; reduction
A small 5 mm renal calculi in a patient’s KUB image would represent:
No change in exposure technique
As a patient is undergoing a colon examination, you notice under fluoroscopy the presence of colonic diverticuli in the descending and rectosigmoid colon. As you prepare for follow-up radiographs, you would determine your exposure technique and…
Make no technique changes for this condition
As you perform a KUB radiograph on an elderly cancer patient who is cachexic and emaciated, you select AEC for the exposure. In order to achieve optimum image quality, you should:
Allow the AEC system to adjust technique for the patient’s condition
