The use of contrast material as a means for visualizing human anatomy has a long history.Regardless of the type of contrast media,the purpose for using contrast media is to
A) take advantage of Compton interactions and increase the amount of remnant radiation.
B) enhance the low subject contrast of anatomic structures.
C) improve gastric motility and digestion.
D) improve the contrast between high contrast structures such as bone.

Question

Quizplus · Accepted Answer

The purpose of using contrast media is to enhance the low subject contrast of anatomic structures, allowing for better visualization of specific tissues or organs. Contrast material can help differentiate between normal and abnormal tissue, identify lesions or tumors, and help guide interventional procedures. Option A is incorrect as Compton interactions reduce image contrast. Option C is incorrect as contrast material is not used for improving gastric motility and digestion. Option D is partially correct, but the purpose of using contrast media is not limited to high contrast structures such as bone.
