Size of the intracerebral ventricles as measured with computer tomography, encephalography and echoventriculography

Ventricular size in a total of 192 patients was determined with computer tomography (CT), encephalography (Enc) and echoventriculography (echo-VG). There was good correlation (greater than or equal to 0.80) between the values for the size of the lateral ventricles obtained with all three methods. Correlation between values for the width of the third ventricle: CT/Enc and CT/echo-VG: poor; Enc/echo-VG: good ( = 0.85). Both at computed tomography and encephalography there was poor correlation between anterior horn index and the width of the third ventricle.
