o bjectives: to determine the diagnostic accuracy of magnetic resonance angiography (mra) compared to intra-arterial digital subtraction angiography (dsa) in detection of intracranial aneurysms in those suffering from acute subarachnoid hemorrhage (sah). m e thods: this observational diagnostic study was performed at a tertiary teaching hospital and reference center in shiraz, iran. we included...

The intraarterial digital subtraction angiography (DSA) of 52 patients with hepatic tumors was retrospectively reviewed. In 18 patients, intraarterial DSA was compared with conventional angiography. With DSA, the displacement of arteries, arterial encasement and tumor vessels were equally well identified on comparison with conventional angiography. DSA was superior to conventional angiography i...

Three-dimensional (3D) digital subtraction angiography (DSA) is the latest development in the neurovascular imaging armamentarium. 3D-DSA combines the anatomic resolution of DSA with 3D visualization abilities previously offered by only CT or MR angiography. 3D-DSA provides more detailed information than does DSA alone in the evaluation of neurovascular lesions, such as cerebral aneurysms. Howe...

PURPOSE To determine the most cost-effective strategy for preoperative imaging performed in potential living renal donors. MATERIALS AND METHODS In a decision-analytic model, the societal cost-effectiveness of digital subtraction angiography (DSA), gadolinium-enhanced magnetic resonance (MR) angiography, contrast material-enhanced spiral computed tomographic (CT) angiography, and combinations...

Recent progress in digital subtraction angiography (DSA) devices makes it possible to perform rotational angiography with high resolution and high sensitivity. We tried intravenous (IV) 3D DSA in patients who had undergone MR angiography (MRA) suggestive of unruptured intracranial aneurysms. IV 3D DSA can be used as an alternative method for imaging unruptured intracranial aneurysms suggested o...

BACKGROUND AND PURPOSE MR angiography is primarily and increasingly used to assess intracranial arterial stenoocclusion. However, MR angiography can cause overestimation of stenosis. Although CT angiography is accurate, it has limitations. Our purpose was to determine whether the accuracy of combined MR angiography and CT angiography is equal to that of digital subtraction angiography (DSA) in ...

BACKGROUND AND PURPOSE The method of choice for detecting or excluding a vertebrobasilar aneurysm still is a matter of debate in patients with a characteristically perimesencephalic pattern of subarachnoid hemorrhage (SAH) on CT. We used decision analysis to compare possible diagnostic strategies in these patients. METHODS A decision analytic model was developed to evaluate the effect of 4 di...

Background/Objective: Multislice computed tomographic (MSCT) angiography is a rapid and minimally invasive method for the detection of intracranial aneurysms. The purpose of this study was to compare MSCT angiography with digital subtraction angiography (DSA) in the diagnosis of cerebral aneurysms. Patients and Methods: In this cross sectional study we evaluated 111 consecutive patients [42(37....
