Abstract

We studied the feasibility of high spatial and temporally resolved imaging by a combination of keyhole imaging, which is a fast imaging method, and a 3.0T MRI system which inherently has a high signal-to-noise ratio (SNR). In keyhole imaging, full k-space reference data are collected, followed by repeated dynamic acquisition of the central low-frequency data alone, and this makes dynamic acquisition faster. The purpose of our article is to describe the effects of the reference data on the reconstructed dynamic images with the assumption of vessel visualization. For efficient use of keyhole imaging, it is important to optimize the keyhole percentage and timing of reference data acquisition for the object of interest.
