SDTM. Late Gadolinium Enhancement

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.

Row 1:	Shows a cardiac MRI for participant 201.
Row 2:	Shows a cardiac MRI for participant 202 with a different MRI machine. The time of the procedure was not available so only the date is shown in the PRSTDTC variable.

Please add a row column to your dataset.

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.

Row 1:	Shows the late gadolinium enhancement (LGE) is positive for the overall Left Ventricle for participant 201.
Row 2:	Shows the late gadolinium enhancement (LGE) overall Left Ventricle percentage is 40% for participant 201.
Rows 3-18	Shows the segmental late gadolinium enhancement (LGE) values for each of the left ventricle segments for participant 201.
Row 19:	Shows the total late gadolinium enhancement (LGE) positive segments for participant 201.
Rows 20-23:	Shows the segmental late gadolinium enhancement (LGE) percentage for each of the positive LGE segments for participant 201.
Row 7:	Shows the late gadolinium enhancement (LGE) is negative for participant 202.

Please add a row column to your 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.
