This example dataset shows the findings of a cardiac magnetic resonance imaging procedure related to late gadolinium enhancement. The level of granularity varies with the type of test used. Research requirements will determine what level of granularity is needed. For example, a study may not include the analysis method. Alternatively, researchers may be interested in understanding if the assessments were done visually or with quantitative methods. If the study includes an assessment of each segment, such as with the Segmental Late Gadolinium Enhancement Percentage, there may be interest in representing the quantitative analysis method. This example illustrates how to represent this type of information. (Ref: https://jcmr-online.biomedcentral.com/articles/10.1186/1532-429X-16-45)
The procedures (PR) domain is used to represent diagnostic, preventive, and therapeutic activity. The example PR dataset shows the cardiac magnetic resonance imaging with two different MRI machines. The variable SPDEVID represents 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 below.

The Cardiovascular System Findings (CV) domain represents physiological and morphological findings related to the cardiovascular system, including the heart, blood vessels and lymphatic vessels. The findings from the CMR procedure for LGE are noted in this example. If LGE was not performed, it would not appear in the dataset.
The ANMETH variable describes the analysis method applied to obtain a summarized result. Analysis 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) which in this case applies to the CMR imaging. There are may be machine-centric analysis methods inherit to the type of machine (e.g., full-width half maximum, 5 standard deviations, 6 standard deviations). https://jcmr-online.biomedcentral.com/articles/10.1186/1532-429X-12-21 These may be of interest for the study and [7] If this information is of interest to the study, it would be represented using the ANMETH CVANMETH 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.
