The bicaudate-temporal index can help to evaluate the size of a lateral ventricles.
Exam: CT head scan, axial views
Parameters:
(1) minimum distance between the caudate nuclei in the lateral ventricles in cm
(2) maximum internal skull diameter in cm (taken perpendicular to the long axis, temporal-parietal region)
bicaudate-temporal index =
= (bicaudate distance) / (maximum skull diameter)
