The procedures (PR) domain contains interventional activity intended to have diagnostic, preventive, therapeutic, or palliative effects. The example PR dataset below shows the cardiac magnetic resonance imaging with two different MRI machines. The variable SPDEVID sponsor device identifier (SPDEVID) variable is used to represent the imaging device identifier information provided in the DI dataset below.

The device identifiers (DI) domain is used to represent the device information details. For this particular example, the device type was the only detail of interest to the researchers. The DI Sequence number (DISEQ) is specific to each device; note there are two different CMR Scanners each scanners noted with different identifiers values in the Sponsor Device Identifier ( SPDEVID ) variable and each have variable. Each scanners has a value of "1" for the DISEQ variable . The reason because since there is only one record or row for each device.
