UNLABELLED Cervical and intracranial arterial evaluation is an important issue for acute ischemic stroke (IS). OBJECTIVE Compare the use of the neurovascular ultrasound examination (NVUE) to digital subtraction angiography (DSA) in acute IS patients for diagnosing significant extracranial and intracranial arteriopathy. METHOD Nonconsecutive patients with IS or transient ischemic attack admi...

The entire vascular tree of 58 lower extremities with high-grade critical limb ischemia (CLI) was assessed with three-station time resolved imaging of contrast kinetics (TRICKS) magnetic resonance angiography (T-MRA) and correlated with digital subtraction angiography (DSA) examinations and Trans-Atlantic Inter-Society Consensus II (TASC II) guidelines. Kappa (κ) statistics were utilized to eva...

AIMS Three-dimensional reconstruction of intracranial vessels is of interest for evaluation of aneurysms. This study determined diagnostic difference of three-dimensional digital subtraction angiography (3D-DSA, volume-rendering image) versus 2D-DSA for evaluating ruptured intracranial aneurysms, particularly focusing on the size of aneurysms as depicted in both images. SETTINGS AND DESIGN Si...

Duplex sonography and intravenous digital subtraction angiography (DSA) were compared in 102 carotid bifurcations in 51 patients. Sonograms were adequate in 87 (85%) vessels and angiograms were adequate on at least one view in 86 (84%) vessels. An adequate image was obtained by one or the other method in all but two vessels (98%). Although most vessels were seen well on one view only on DSA, ag...

BACKGROUND AND PURPOSE In evaluating intracranial tumors, a safe low-cost alternative that provides information similar to that of digital subtraction angiography (DSA) may be of interest. Our purpose was to determine the utility and limitations of a combined MR protocol in assessing (neo-) vascularity in intracranial tumors and their relation to adjacent vessels and to compare the results with...

BACKGROUND AND PURPOSE To compare multisection CT angiography (CTA) analyzed with source/maximum intensity projection (MIP) images as well as semiautomated vessel analysis software with intra-arterial digital subtraction angiography (DSA) in detection and grading of carotid artery bifurcation stenosis. METHODS Consecutive patients with sonography evidence of a marked internal carotid artery s...

BACKGROUND AND PURPOSE The purpose of this work was to study the validity of MR angiography (MRA) for identification of spinal arteriovenous (AV) abnormalities. MATERIALS AND METHODS Thirty-four consecutive patients with suspicion of spinal vascular abnormalities underwent digital subtraction angiography (DSA) after MRA. The level and side of the suspected spinal dural arteriovenous fistula (...

Background and Aims : Diagnostic digital subtraction angiography (DSA) DSA with percutaneous transluminal angioplasty (DSA-PTA) are common procedures for diagnosing treating symptomatic lower extremity arterial disease (LEAD). However, organ damage following DSA-PTA is often under-recognised hence undiagnosed. The aim of the current study was to assess effect remote ischemic preconditioning (RI...
