This dataset is designed to have the most reliable ground truth myocardial contours from short-axis MRI. We have collected not too many cases (only 15) from different vendors (3 MR systems) with multiple pathologies (1 healthy and 3 cardiac disease). We then asked 7 top MR core-labs from the Society of Cardiovascular Magnetic Resonance to manually draw myocardial contours by their expert reader. No restriction on how to draw these contours. We simply asked them to use the standard clinical protocol for MRI analysis applied in their labs. We derived the consensus contours from their manual contours.

Deriving consensus contours (bottom) from 7 expert-drawn contours (top).

Performance report

When you submit your contours, we will process your contour files and provide you with the following reports:

Contour Snapshots

Plots of your contours and the consensus contours for each image.

Bland-Altman Plots

Comparisons of EDV, ESV, LV mass and ejection fraction.

Disagreement Plots

Disagreement areas with the consensus contours for each contour.

Scatter Plots

Scatter plots of EDV, ESV, LV mass and Ejection Fraction.

Reader Biases

Disagreement areas with the consensus contours for each contour.

Intersection Plots

Intersection areas to visually show Dice coefficients.

Myocardial Area

Spreadsheet of endocardium and epicardium areas for each image.

Dice Coefficients

Spreadsheet of Dice coefficients for each image.

LV Functions

Spreadsheet of EDV, ESV, EF, LVM and epicardial volumes.
