This example dataset shows the findings associated with a Cardiac Magnetic Resonance Imaging procedure related to late gadolinium enhancement.
The Procedures (PR) dataset is an interventions domain that represents diagnostic, preventive, and therapeutic activity. The PR dataset shows the cardiac magnetic resonance imaging with two different MR machines.
Describe the analysis method for LGE - three different methods:
- Full-width half maximum
- 5 standard deviations
- 6 standard deviations
These are represented in the ANMETH variable describes the analysis method applied to obtain a summarized result. 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.

The Cardiovascular System Findings (CV) dataset contains 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 Procedure Agent (AG) dataset is an interventions domain that contains the agents administered to the participant as part of a procedure or assessment. The AG dataset shows the timing of the Gadolinium based contrast, GD-DOTA. Participant 202 did not have the time the contrast was given available so only the date is represented in AGSTDTC variable.
