Postoperative angiography for aneurysm surgery is essential in identifying those aneurysms that have been inadequately clipped, allowing for additional corrective surgery. The current standard of reference for the postoperative evaluation of clipped aneurysms is digital subtraction angiography (DSA). However, DSA is an invasive method requiring arterial puncture and intraarterial catheter manip...

BACKGROUND AND PURPOSE To follow up patients with coiled intracranial aneurysms, magnetic resonance angiography (MRA) is a promising noninvasive alternative to current standard intra-arterial digital subtraction angiography (IA-DSA). MRA test results do not always concord with those of IA-DSA, and the impact of discrepancies on health benefits and costs is unknown. We evaluated the cost-effecti...

Computed tomographic angiography (CTA) is a well-established non-invasive investigation for this neurological presentation to exclude intracranial aneurysms. However, dural arteriovenous fistulae with anterograde venous drainage only can be missed by CTA. Here we reported two patients with painful complete third nerve palsy and dural carotid cavernous fistulae with anterograde venous drainage o...

Brain death results when irreversible intracranial circulatory arrest, involving both the internal carotid and intracranial vertebral basilar systems, occurs despite preservation of extracranial circulation . To document the absence of intracranial blood flow and establish the irreversibility of the condition, intraarterial cerebral angiography and radionuclide cerebral angiography have become ...

A simple, practical method of applying incremental dynamic computed tomography (CT) to the imaging of 20 carotid bifurcations is described. The results are compared with those obtained by conventional carotid angiography and intravenous digital subtraction angiography (DSA). Conventional angiography provided additional information about the carotid bifurcation in only one of 14 cases, while inc...

PURPOSE To prospectively determine, for both digital subtraction angiography (DSA) and contrast material-enhanced magnetic resonance (MR) angiography, the accuracy of subjective visual impression (SVI) in the evaluation of internal carotid artery (ICA) stenosis, with objective caliper measurements serving as the reference standard. MATERIALS AND METHODS Local ethics committee approval and wri...

The incidence of stroke would be decreased if the vertebral artery stenosis could be diagnosed early and therapy effectively. Presently, the Digital Subtraction Angiography (DSA) is a new computer-assisted radiographic procedure to diagnose the vertebral artery stenosis, and can provide clinical information for therapy. In this paper, the hemodynamic characteristics of the vertebral artery sten...

Advances in imaging technology have provided new diagnostic methods for assessment of cerebral vascular perfusion and quantitative analysis of the microcirculation during cerebral surgery. In this article, a range of imaging procedures are described: Digital Subtraction Angiography (DSA) and Three-Dimensional Computed Tomography Angiography (3D-CTA), Indocyanine Green Video Angiography (ICGVA),...

Background Quiescent Interval Single Shot (QISS) has emerged as a robust technique for non-enhanced angiography of peripheral arteries (1). It has been clinically validated with contrast enhanced magnetic resonance angiography (CE-MRA) and digital subtraction angiography (DSA) (2,3). Both of these validation studies were performed at 1.5T field strength. Although the initial experience with QIS...

Objective: Evaluation of peripheral arterial disease with 64-detector multi-slice CT angiography (MDCTA) and comparison of the results with the results of digital subtraction angiography (DSA), a standard reference. Materials and Method: The written informed consent of the patients and ethics committee approval were obtained. The retrospective study group consisted of 28 patients with a diagnos...
