Cardiovascular imaging tests may use different methods such as echocardiography, multigated acquisition scan, cardiac angiography, and cardiac magnetic resonance imaging (CMR) imaging. The focus of this document is on tests done using the method of cardiac magnetic resonance imaging. Each example has a different focus to aid the end users in representing the data. This
The following concept map highlights the different components or aspects that can be represented for study purposes. The study requirements define what level of detail is required for each study. The examples provide a way illustrate how to represent the data if that level of detail is needed for the study.

The examples noted below provide use cases for different tests for CMR. The Systolic function example provides subsections listed below include examples illustrating the data representation using the SDTM for various cardiovascular imaging tests.
- The Basic Systolic Function example includes parameters related to the overall basic cardiac function
...
- (e.g., ejection function, cardiac output, systolic and diastolic volumes).
...
...
- example shows how to represent
...
- multiple CMR machines,
...
- tests related to LGE, and contrast administration.
...
- The Parametric Mapping example includes information about the procedure, the CMR device used, and cardiovascular tests for parametric mapping
...
- (e.g., longitudinal relaxation time (T1 mapping)
...
- and transverse relaxation time (T2 mapping)) for different locations and segments.
...
- The example also shows how to represent imaging quality assessments and instances when a CMR test is not done
...
- . Additionally, this example shows how device information can be represented since device parameters may impact the
...
- results of these types of tests.
- The Circumferential and Longitudinal Strain example includes the representation of an analysis method (e.g., "feature tracking").
