This example Procedures (PR) dataset includes the SPDEVID variable to show what device was used and the PRREFID variable to represent the accession number or procedure reference identifier associated with the specific procedure. SPDEVID was used to link this PR record to the device records.

This example cardiovascular system findings (CV) dataset shows how to represent longitudinal relaxation time, transverse relaxation time, and extracellular volume findings from CMR imaging. This example includes records for an unreadable image and an unperformed test. For these records, CVSTAT was populated with "NOT DONE" and CVREASND was populated with the reason the result was not provided or the procedure was not done. An NSV was 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 (CVTPT = BEFORE and CVTPTREF = CONTRAST ADMINISTRATION). | Rows 7-8: | Show the longitudinal relaxation time and myocardial extracellular volume for the LEFT VENTRICULAR BASAL ANTEROSEPTAL SEGMENT after contrast (CVTPT = AFTER and CVTPTREF = CONTRAST ADMINISTRATION). | 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).
