Rowcaps

Rows 1-6:	Show the T1 Longitudinal Relaxation Time, and the T2 Transverse Relaxation Time, (Native T1 Mapping) for different segments of the heart prior to contrast for CMR.
Rows 7-8:	Show the T1 Longitudinal Relaxation Time, Native T1 Mapping, and Extracellular volume for different segments of the heart after contrast for CMR.
Row 9:	Shows participant 302 had a CMR procedure that was unreadable, CVREASND = "NON-EVALUABLE". This is denoted by CVTESTCD of CVALL for " CARDIOVASCULAR SYSTEM FINDINGS with the METHOD of "CARDIAC MAGNETIC RESONANCE IMAGING".
Row 10:	Shows participant 303 did not have a CMR procedure because they were unable to place an intravenous access line, CVREASND = "UNABLE TO PLACE INTRAVENOUS LINE".
