QUANTIFICATION OF CEREBRAL VENTRICULAR VOLUME IN ENGLISH BULLDOGS

Quantitative measurement of cerebral ventricle volume of eight English bulldogs was performed using magnetic resonance (MR) imaging. The mea n ventricular volume was 14.8 ml. with a range of 8.6 ml.-38.1 ml. The mean ventricular volume of two beagles was 2.2 ml with a range of 0.7 ml.-3.7 ml, The percent of intracranial volume occupied by ventricle was found to be significantly larger in bulldogs (14.0%; S.D. = 7.9%) than in beagles (Range = 1.0-4.8%). The relationship between the perce nt of intracranial volume occupied by ventricle and measurements of bo dy weight, age, sex, and various measures of skull anatomy of the bull dog was also determined, The relationship between ventricular volume a nd neurologic dysfunction was examined, There was a possible trend bet ween high percent of intracranial volume occupied by ventricle and low body weight, This study will serve as a pilot study for examining the relationship between ventricular volume and neurologic disease in bul ldogs.
