The <strong>Sunnybrook Cardiac Data (SCD)</strong>, also known as the <strong>2009 Cardiac MR Left Ventricle Segmentation Challenge</strong> data, consist of 45 cine-MRI images from a mixed of patients and pathologies: <em>healthy</em>, <em>hypertrophy</em>, <em>heart failure with infarction</em> and <em>heart failure without infarction</em>. Subset of this data set was first used in the automated myocardium segmentation challenge from short-axis MRI, held by a MICCAI workshop in 2009. The whole complete data set is now available in the CAP database with <strong>public domain license</strong>. <br> Classification There are four pathological groups in this data set, which were classified based on (K Alfakih et al., JMRI 2003) paper, i.e.: Heart failure with infarction (<strong>HF-I</strong>) group had ejection fraction (EF) &lt; 40% and evidence of late gadolinium (Gd) enhancement. Heart failure without infarction (<strong>HF</strong>) group had EF &lt; 40% and no late Gd enhancement. LV hypertrophy (<strong>HYP</strong>) group had normal EF (&gt; 55%) and a ratio of left ventricular (LV) mass over body surface area is &gt; 83 g/m2. Healthy (<strong>N</strong>) group had EF &gt; 55% and no hypertrophy. The following table shows group statistics written as average (stddev) : <br> Availability The Cardiac Atlas Project provides the dissemination of the Sunnybrook data by hosting them in the CAP databases. Finite element models (see supporting files section below) derived from these data are also provided. The whole complete data are available for any users, including the guest user account.
