CVRG Challenge: Temporal Data

• ECG, Cardiac MRI, Multi-slice Cardiac CT, Cardiac PET/CT, Nuclear Perfusion Imaging …

• Analysis and integration of cardiac electrical, mechanical activity, perfusion and hemodynamics

• Temporal query and analysis across patient populations• Integration with clinical and “omic” data
