title: Intracranial tumors examined by intraarterial DSA: a comparative angiography study.
abstract: We compared intraarterial digital subtraction angiography (DSA) studies with those of conventional angiography, performed for 24 patients who had intracranial tumors. Intraarterial DSA is more effective in evaluating tumoral blush and venous phase, but neovascularization can be judged better by conventional angiography. In most cases, intraarterial DSA can replace conventional angiography for the diagnostic and preoperative evaluation of intracranial tumors. However, conventional angiography remains the technique of choice for the evaluation of neovascularization or if the patient is not cooperative.
