The aim of this work is to report initial clinical
experience of DIfferential Subsampling with Cartesian
Ordering (DISCO) dynamic breast examinations. In DISCO
k-space is divided into central and outer portions. The
outer portion of k-space is segmented into a number of
equal distributions regions via a pseudo-random
segmentation scheme. The central portion of k-space is
sampled every temporal frame while the outer edges are
subsampled sequentially. Temporal resolution is
minimised by implementing view-sharing. The results of
this work demonstrate that by utilising DISCO both high
spatial and high temporal resolution dynamic sequences
are possible.
