Case Studies - Application of PAI > Mouse & Human Cardiac MR Cine Left Ventricle Segmentation

Mouse data

Mouse bright-blood cardiac cine data was collected from internal sources and contained conventional prospectively-gated as well as Bruker IntraGate and IntraGate UTE (ultrashort echo time) time. The mixture of source data resulted in a range of pixel size, number of cardiac cycle frames, as well as blood contrast/artefacts. All series were split by frames and slices to be treated as individual 2D data. Each series was rotated such that the right ventricle was displayed on the left of screen and cropped using a 10 x 10 mm box. Reference segments for myocardial epi- and endo- contours were created manually using the paintbrush VOI tools and masking functionality. Images and reference segments were associated in a database.

Human data

Human bright-blood cardiac cine data was shared in a private collaboration. 10 subjects were available.

The subjects had between 14-18 slice coverage of the myocardium and 25 frames of the cardiac cycle. These were split by frames/slices to be treated as individual 2D data. Reference segments for myocardial epi- and endo- contours were manually drawn using VOI tools and images associated with reference segments in a database.
