Midline angio-tomography of the posterior fossa.
Interpretation of the angiographic findings in posterior fossa angiography can be improved by a simple angiotomographic device which gives a midline tomography of the posterior fossa. Especially the vessels around the brain stem and close to the midline can be well seen and this is especially helpful with lesions in the brain stem and the anterior part of the posterior fossa. A few examples are given of midline angiotomography which demonstrates the advantages of this technique.
