This case-sensitive code system http://hl7.org/fhir/uv/imaging-service-request-ig/CodeSystem/dicom-modality-lut-and-rescale-types defines the following codes:

CodeDefinition
OD The number in the LUT represents thousands of optical density. That is, a value of 2140 represents an optical density of 2.140.
HU Hounsfield Units (CT)
US Unspecified
MGML mg/ml
Z_EFF Effective Atomic Number (i.e., Effective-Z)
ED Electron density in 1023 electrons/ml
EDW Electron density normalized to water in units of N/Nw where N is number of electrons per unit volume, and Nw is number of electrons in the same unit of water at standard temperature and pressure.
HU_MOD Modified Hounsfield Unit
PCT Percentage (%)
