Final answer:
High contrast is desired for radiographs of the abdomen, and it can be achieved by using a high kVp technique.
Step-by-step explanation:
The type of contrast desired for radiographs of the abdomen is high contrast. It can be achieved by using a high kVp technique.
High contrast is important for abdominal radiographs because it helps to differentiate between different structures and identify any abnormalities or pathology. This is achieved by using a high kVp technique, which means using a higher kilovoltage peak setting on the x-ray machine. Higher kilovoltage allows for greater penetration of the x-rays through the body, resulting in a higher contrast image.
