The application of special roentgenologic techniques to the diagnosis of tumors of the optic nerve and chiasm can permit the demonstration of the size and location of the tumor prior to therapy. This report describes three special techniques which can be applied to the diagnosis of tumors of the optic nerve and chiasm. These techniques are selective carotid angiography, tomography of the chiasmatic region in association with pneumoencephalography, and the subtraction technique which can be used in conjunction with angiography.

Selective Carotid Angiography  The introduction of the catheter technique to carotid angiography13 has simplified a selective demonstration of the internal and external carotid circulation.10 The advantages of this technique are reduced incidence of intramural injections, greater mobility of the patient, no overlapping of the internal and external carotid circulation, and better opacification of the particular carotid circulation being studied with consistent filling of the ophthalmic artery on internal
