  • Title: [Parametric visualization of cerebral perfusion by intravenous digital angiography].
    Author: Schüller H, Standop M, Sobbe A, Leipner N, Harder T.
    Journal: Rofo; 1987 Mar; 146(3):342-7. PubMed ID: 3031768.
    Abstract:
    Intravenous digital subtraction angiography is often used for evaluation of the extracranial and major intracranial vessels. The information obtained by this examination concerning cerebral perfusion is usually judged visually. In 50 patients a time-density curve at a specific point was analysed using 128 X 128 matrix. The level of grey scale at the moment of arrival of the bolus permits estimation of the haemodynamics of the intracranial vessels and provides a simple demonstration of differences of perfusion.
