Late Gadolinium Enhancement

The Procedures (PR) domain contains interventional activity intended to have diagnostic, preventive, therapeutic, or palliative effects. This example PR dataset shows the CMR imaging with 2 different MRI machines. The sponsor device identifier (SPDEVID) variable is used to represent the imaging device identifier information provided in the DI dataset.

This example CV dataset shows the results of the LGE test measured using CMR imaging. The analysis method describes the method of secondary processing applied to a complex observation result (e.g., an image, a genetic sequence). There may be machine-centric analysis methods inherit to the type of machine (e.g., full-width half maximum, 5 standard deviations, 6 standard deviations).[7] If this information is of interest to the study, it would be represented using the CVANMETH variable.The Procedure Agents (AG) domain contains the agents administered to the subject as part of a procedure or assessment. This example AG dataset shows the timing of the gadolinium-based contrast, Gd-DOTA. The time the contrast was given to participant DMD-LGE-01-202 was not available, so only the date is represented in AGSTDTC variable.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 sequence number (DISEQ) is specific to each device; note there are 2 different CMR scanners noted with different values in the SPDEVID variable. Each scanner has a value of "1" for the DISEQ variable since there is only 1 record or row for each device.The RELREC dataset is used to describe the relationship between 2 or more records in different domains.
