The Noquist method for accelerated cardiac imaging takes advantage of the spatiotemporal redundancy whenever the field of view contains static regions. Notable characteristics of Noquist compared to alternative methods include full preservation of spatiotemporal resolution. This study reports first results of a implementation of Noquist for a prospectively gated dynamic cardiac imaging method (GE FastCARD). A conventional image and a Noquist-accelerated image with the same acquisition parameters are compared. For the same acquisition time, Noquist-accelerated image shows clear improvement in image clarity. The improvement in image resolution clearly outweighs the SNR penalty associated with Noquist.
