A new interactive computer system has been developed to measure ventricular volume from CAT scans. Testing this system of phantoms demonstrated an accuracy to within 16%. Then a series of scans of patients with obstructive hydrocephalus was analyzed using both traditional linear measures and the computer method. None of the traditional measures were directly proportional to the calculated volume. The area measure of ventricular volume correlated well with the computer-generated values. Clinical studies which attempt to quantitate ventricular volume should use a computerized or planigraphic measure.
