Measurements of the normal ventricular system with computer tomography of the brain. A preliminary study on 44 adults.

The brains of 44 normal adults were examined by computer tomography (CT) with the fine matrix EMI scanner. Measurements of various parts of the ventricular system showed a sexual difference and an increase with age. Absolute measurements are preferred to indices or ratios. Comparison with the same parameters in pneumoncephalography and ventricular casts showed good correlation. The need for larger investigations of the normal population is stressed.
