In MRI, relatively small differences in what property between tissues can be resolved?

• A. Density differences
• B. Brightness differences
• C. Contrast differences
• D. Texture differences

Answer: (C)

The essential idea is that MRI resolves differences in tissue contrast. Tissues differ in how they respond to the magnetic environment because of properties like T1 and T2 relaxation times and proton density. Those differences change how bright each tissue appears on a given image. The resulting contrast—the relative brightness differences between neighboring tissues—lets us distinguish structures that might have similar densities or textures. By selecting different imaging sequences, you emphasize certain contrasts (T1, T2, or proton density) to reveal subtle tissue differences. Density isn’t directly mapped as a standalone property in MRI, brightness is the visible outcome of the contrast, and texture refers to pattern rather than a singular tissue property. So the best answer is that MRI resolves small differences in contrast between tissues.
