Which statement best describes a high kVp, low mAs technique in abdominal radiography?

Explanation:
High kVp increases beam energy, which makes tissues more uniformly attenuated and raises scatter. That reduces subject contrast, so the image looks greyer and less differentiated. Meanwhile, lowering mAs reduces the number of photons reaching the detector, which directly lowers the patient’s radiation dose. So using a high kVp with low mAs achieves a smaller dose while sacrificing image contrast. In abdominal exams, this trade-off is often acceptable because the thicker body part benefits from better penetration, and the resulting image dose can be kept lower even though the contrast is diminished.
