On CT an AML is usually a well-defined, heterogeneous tumor, located in the renal cortex and containing areas of fat density of -20 HU or less. WebProton density (PD) is the most basic MRI measure, representing the apparent concentration of water protons (mobile hydrogen atoms) in each voxel. What is proton density image? Proton density (PD) weighted images are related to the number of nuclei in the area being imaged (number of hydrogen protons), as opposed to the magnetic …
