Angiotomography in cerebral angiography.

In 63 cases, angiotomography was performed during cerebral angiography. These findings were described and the purpose, significance and indication discussed.The apparatus for radiography was CGR Princeps 50 cephalography apparatus, with the angle of swing of 30°.This is quite useful for visualization of deep cerebral vein especially internal cerebral vein.When indication such as cerebral aneurysm, brain tumor and congenital anomaly are adequately selected, vascular density is not interfered with bone density and difficulty for interpretation to overlapping of blood vessels is solved.
