Contrast-to-noise ratios in maximum intensity projection images

Magn Reson Med. 1992 Jan;23(1):130-7. doi: 10.1002/mrm.1910230114.

Abstract

We present a statistical analysis of the maximum intensity projection (MIP) algorithm, which is commonly used for MR angiography (MRA). The analysis explains why MIP projection images display as much as a twofold increase in signal- and contrast-to-noise ratios over those of the source image set. This behavior is demonstrated with simulations and in phantom and MRA image sets.
