The most important thing to remember is that you should not invest time in memorizing these. If you need a specific value/measurement updated/corrected do let us know in the comments. This is a work in progress as there are multiple reference values in radiology. The page also includes criteria for various pathologies for each organ system. We have tried to compile the list of normal reference values and measurements in diagnostic radiology for all systems in one place.
