Abstract

The theoretical information content, defined by Shannon, is proposed as an objective measure of MR image quality. This measure takes into account the CNR, scan resolution and the field of view. It is used to derive an optimum in the tradeoff problem between image resolution and CNR, and as a criterion to assess the usefulness of high-resolution MR images. The result tells that, for a given total acquistion time, an optimum value of of resolution can be found.
