Fig. 3From: Non-invasive quantification of cardiac stroke volume in the edible crab Cancer pagurusStroke volume, heart rate and ejection fraction of C. pagurus at different water PO2 determined by MRI. a) Stroke volume (SV) and water PO2. b) ejection fraction (EF) and heart rate (HR). The width of the bars represents the scan time (50 min). Heart rates are shown for the first and last slice of a multi-slice IntraGate© CINE MRI scanBack to article page
