Serial angiotomography in supratentorial tumors.

Serial angiotomography is a selective investigative method which contributes to exact differential diagnosis and localization of the tumor. With the localization near the midline of the supratentorial tumors it can occasionally be the only arteriographical method which will bring a definite result. With basal processes the relationship of the tumor to the bones and dura can be demonstrated more accurately. In addition angiotomography brings new haemodynamic aspects with regard to the circulation time and intensity of the tumor stain of glioblastoma.
