Abstract

In order to measure the accuracy of volume determinations of brain tissues from MRI images, a number of phantoms simulating these tissues were constructed and imaged in a clinical imager operating at 1.5 T. Method consisted of measuring signals from pure tissues and volume of interest and then solving the equations for partial volume. Comparisons of the results obtained from the images with the true volumes in the phantom yielded accuracies (rms) which ranged from 1.6% for a simple phantom to 6.7% for more complex but realistic phantoms.
