title: Posterior fossa, aqueduct and fourth ventricle of the living mouse studied by positive contrast and plain radiography.
abstract: Radiographic techniques have been applied to the measure the size, volume and relationships of the posterior fossa, aqueduct and fourth ventricle in two strains of laboratory mice. Significant differences in the size of posterior fossae between strains were observed. Using ventriculography in the living mouse, the outflow tract of the fourth ventricle was demonstrated, together with a communication that exists between the third ventricle and the subarachnoid space.
