The use of the 80 to 90 kV (analog) technique (as opposed to 70 kV) with a corresponding mAs change for an AP pelvis projection will result in:
A)increased radiographic contrast.
B)improved spatial resolution.
C)reduction in gonadal dose.
D)none of the above; the difference is not measurable.

Question

Quizplus · Accepted Answer

Increasing the kVp (from 70 to 80-90 kV) while adjusting the mAs accordingly can lead to a reduction in patient dose, including gonadal dose, because higher kVp settings penetrate more effectively, requiring less radiation (lower mAs) to achieve the desired image density.
