The advantages of cardiac cine MRI are often limited by its long acquisition and breath-held requirement. To overcome these limitations, we have introduced a navigator based spiral SToRM to acquire free breathing and ungated cardiac cine MRI in a short acquisition time. Our algorithm is fully automated and does not depend on explicit binning. It gives improved image quality compared to the existing self-gated methods. Post-reconstructions, the time series can be processed to extract cardiac cycles at different respiratory phases, facilitating the estimation of anatomical and functional evaluation of the heart.
