Correlation between the appearances of the ventricular system at carotid angiography and computer assisted axial tomography.

ABSTRACT

Computer assisted axial tomography and the venous phase of carotid angiography provide complementary assessments of the ventricular and paraventricular structures. The computer assisted tomography more readily defines the ventricular system, but can prove weak in differentiating paraventricular gliomas, solitary metastasis and infarcts. Angiography plays a major role in differentiating between these three conditions, but is poor in accurately localizing and identifying intra- and paraventricular hemorrhage which is characteristically and expeditiously uncovered by C.T. scanning.
