Module Description

Program title SUV Factor Calculator
Program description This command line interface module takes a PET DICOM series and creates a Real World Value Mapping (RWVM) file including 4 types of Standardized Uptake Value conversion factors (SUVbw, SUVlbm, SUVbsa, SUVibw).

Usage

Use Cases, Examples

The patient size correction factors are summarized here, where weight is in kilograms and height is in centimeters.

  • SUVbw:
    • males & females: weight
  • SUVlbm:
    • males: 1.10 * weight - 128 * (weight/height)^2
    • females: 1.07 * weight - 148 * (weight/height)^2
  • SUVbsa:
    • males & females: weight^0.425 * height^0.725 * 0.007184
  • SUVibw:
    • males: 48.0 + 1.06 * (height - 152)
    • females: 45.5 + 0.91 * (height - 152)
