✦ Synopsis

Abstract

Small vessels in three‐dimensional MR angiograms have low visibility in maximum‐intensity projection images because of their low contrast. In a previous study, we had two nonlinear filters that appeared to give significant improvement in small vessel detail. In this paper, we report on a generalization of this filter that allows a more general modeling of the vessels and a more complete suppression of background. One implementation of the general filter gave a vessel mean contrast‐to‐noise ratio that is 2.52 and 3.51 times higher than the vessel mean contrast‐to‐noise ratio obtained using our previously reported maximum‐minimum (max‐min) filter and cross‐ section filter, respectively.

## Abstract For a variety of reasons, small vessels have low signal Intensity in magnetic resonance angiography. When the vessel signal intensity is lower than the signal intensity of background tissues, these vessels tend not to be visible on maximum‐intensity‐projection images. The authors develo
