Cardiovascular magnetic resonance of cardiac morphology and function: impact of different strategies of contour drawing and indexing.

Background: Cardiovascular magnetic resonance (CMR) is the gold standard for the quantitative assessment of cardiac volumes, mass and function. There are, however, various strategies for establishing endocardial borders, the cardiac phase used for measurements and the body dimensions used for indexing these results. The aim of the study was to assess the impact of different strategies on reference values.
