Two projection computed tomography: the axial and Towne projections.

It is occasionally necessary in evaluating lesions around the third ventricle and posterior fossa to supplement the axial view with another projection. The authors have routinely used the coronal projection as a second projection. However, the Towne view for computed tomography can be used as a second projection instead of the coronal; it is technically easier and faster to perform than the coronal projection, and provided good evaluation of the posterior fossa and para third ventricular areas in children.
