Description

This study was undertaken to estimate the accuracy of proton density measurements using a standard whole-body MR imager operating at 1.5 T. It was concluded that the hydrogen density of biological tissues can be evaluated at best with an overall error of 10% from MR images for TE>10 ms. This accuracy is insufficient for a pixel-orientated neutron therapy planning. (author)
