CT density corresponds to which MRI term?

Explanation:
CT density reflects how much X-ray attenuation a tissue has, shown as density values on CT. MRI doesn’t measure real density; instead, the image shows how strong the received signal from protons is, which is reported as signal intensity. So, the CT concept of density maps to MRI as signal intensity—the brightness of a voxel on the MRI image. While higher density can influence contrast on CT, MRI terminology uses signal intensity rather than density or brightness, and contrast describes differences between tissues rather than a single voxel’s property.
