In total, 200 cases from the DETERMINE (Defibrillators to Reduce Risk by Magnetic Resonance Imaging Evaluation) cohort are available for this challenge. All the data are in de-identified DICOM format following the HIPAA regulations. Permission to use the data in this challenge has been granted by the DETERMINE study, subject to the CAP-STACOM11 Terms of Data Usage Agreement. Informed consent and local IRB approval have been obtained.
The DETERMINE cohort consists of patients suffering from myocardial infarction and impaired LV contraction. Each case includes short-axis and long-axis views of cine-MRI. These images were acquired with Steady-State Free Precession (SSFP) MR imaging protocol with typical thickness ≤ 10mm, gap ≤ 2mm, TR 30-50ms, TE 1.6ms, flip angle 60 deg, FOV 360mm and 256x256mm image matrix. Patients were asked to hold their breath for 8-15 sec. during MR acquisition session. The studies were acquired at multiple sites using a range of different scanner types and manufacturers.

The test set consists of 100 randomly selected cases, each image slice is accompanied by the corresponding ground truth images. Participants may use the test set to develop, to train or to test their segmentation algorithm.

If you have difficulties to download the whole test set file, we broke it down into the following smaller 10 zip files:
The validation sets consists of 5 sub-groups, each having 20 cases. All sub-groups only contain MRI data from short-axis and long-axis views. No ground truth images are given.
All participants must at least submit their segmentation results from one sub-group. When submitting the segmentation results, please start from the lowest sub-group ID. There are no preferences when we grouped the validation set. All sub-groups were created by random selection.
