Final answer:
High kVp causes low contrast in radiography.
Step-by-step explanation:
High kVp causes low contrast in radiography.
kVp stands for kilovolt peak and is a measure of the energy or penetrating power of the X-ray beam used in radiographic imaging. Higher kVp values produce X-rays with higher energy and greater penetrating power. When the kVp is increased, the X-rays can penetrate through thicker body parts or denser tissues more easily, resulting in less difference in brightness or contrast between structures in the image.
For example, a high kVp setting may be used in chest X-rays to ensure that the X-rays can pass through the ribs and lungs to create an image with appropriate contrast between the different structures.
