What is the primary reason that different tissues in the body absorb X-rays differently?.
Model answer
What a good answer should say
- Different tissues have varying densities and atomic compositions, which affects how they interact with X-ray photons.
Explanation
Why this works
This answer is strong because it identifies the cause (varying densities and atomic compositions) and explains the mechanism (interaction with X-ray photons) leading to the effect (different absorption levels). The consequence is that this differential absorption results in varying contrast in X-ray images, aiding in diagnosis.
