Respiratory variation in ventricular volume can potentially provide clinically important information in cardiac diseases involving left ventricular stiffness changes, and can be measured using respiratory resolved imaging. 3D double-golden-angle radial data were acquired during free breathing, and respiratory self-gating signals were extracted from k-space. All radial spokes were sorted into 8 respiratory phases and one end-diastolic cardiac phase and left ventricular end-diastolic volume (EDV) was segmented from a short-axis image stack. Respiratory induced changes in EDV were demonstrated and changed 9.0±2.3 % with respect to maximum expiratory EDV.
