## EEEE.2 Encoding Diffusion Model Parameters for ROIs in Measurement Report SR Documents

This example shows how to describe the mean ADC value of a region of interest on a volume of ADC values obtained from a pair of B0 and B1000 images fitting the log ratio ot two samples to a mono-exponential function (single compartment model). In this case the template used is TID 1419 ROI Measurements.

  - HAS CONCEPT MOD CODE (G-C306, SRT, "Measurement Method") = (113250, DCM, "Mono-exponential ADC model")

  - HAS CONCEPT MOD CODE (113241, DCM, "Model fitting method") = (113260, DCM, "Log of ratio of two samples")
