The Cardiovascular System Findings (CV) dataset contains physiological and morphological findings related to the cardiovascular system so it holds the assessments from the parametric mapping. The CV dataset below shows how to represent longitudinal relaxation time, transverse relaxation time and extracellular volume findings from CMR. The timing of the contrast specificity is noted using the CVTPT to note if the CVTEST was done before or after contrast. CVTPTREF associates the timepoints in CVTPT with "contrast administration." In the example below, row 9 represents and unreadable CMR using CVSTAT variable to show the reading was "NOT DONE" and the CVREASND contains variable to show the reason the procedure was not done, or in this case the result . In this case, the reason not provided which was a "Non-Evaluable" image . A similar approach may be used if there is a desire to record that the CMR was not obtained at the specific visit (omitting the poor quality information) and why in the dataset records.

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".
