CINE SPIRAL IMAGING

Interleaved spiral scanning of k-space is an efficient and fast method for imaging dynamic processes, In this article, a cine version of int erleaved spiral imaging is presented, The method is shown to overcome the ''lightning-flash'' artifacts of the conventional triggered (gated ) method. Compared with the segmented k-space 2DFT method, it achieves better temporal resolution in a comparable or shorter scan time, Prel iminary human studies show that the method is a promising tool for ima ging dynamic processes.
