The following example shows parametric mapping (T1, T2, and extracellular volume) results. For brevity, a limited sample of tests after contrast are shown in this example.
The example includes the representation of some device information (i.e., device manufacturer, software, version information, and the specific settings for each subject. Study requirements determine what data is needed. The device identifier is represented using SPDEVID and PRREFID. This information shows what device is used and the accession number or procedure reference identifier associated with the specific procedure for subject DMD-RT-01-301. The SPDEVID variable is used to relate this PR dataset to other records by the device (in this case, the CMR machine).

The example CV dataset below shows how to represent longitudinal relaxation time, transverse relaxation time and extracellular volume findings from CMR. The timing of the contrast specificity is documented using the CVTPT = BEFORE or AFTER contrast administration. This example includes records for an unreadable image and an unperformed test. CVSTAT was populated with "NOT DONE" and CVREASND was populated with the reason the result was not provided or the procedure was not done. A non-standard variable is used to represent image quality.
Rows 1-6:
Show the longitudinal relaxation time and the transverse relaxation time for different segments of the heart prior to contrast.
Rows 7-8:
Show the longitudinal relaxation time and myocardial extracellular volume for different segments of the heart after contrast.
Row 9:
Shows an unreadable CMR result for participant DMD-RT-01-302, CVREASND = "NON-EVALUABLE IMAGE".
Row 10:
Shows participant DMD-RT-01-303 did not have a CMR procedure because they were unable to place an intravenous access line, CVREASND = "UNABLE TO PLACE INTRAVENOUS LINE".

The device identifiers (DI) domain is used to represent the device information details. Characteristics recorded in a DI dataset are those necessary to identify each device to the level of granularity necessary for the study (e.g., to the model level if knowing the actual unit is not necessary, to the serial number level if there is a need to distinguish among units).
