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...

conclusions the advantages of dsa in fluoroscopy-guided transforaminal epidural block and nerve block are identification of the degree of appropriate contrast flow (epidural and nerve root sleeve) and the intravascular administration without overlapping radiodense structures. introduction most pain physicians know that fluoroscopy might improve the safety, accuracy, and efficacy of nerve block;...

Intracranial vessels were examined in 55 patients with both conventional selective catheterization and intravenous digital subtraction angiography using a prototype digital subtraction unit. In 65% of the patients, the digital subtraction angiogram was diagnostic, but the overall quality was inferior to conventional selective angiography. In 22%, the digital subtraction angiogram provided diagn...

OBJECTIVE The objective of our study was to evaluate the diagnostic agreement, the impact on decision making, and the costs of contrast-enhanced MR angiography and digital subtraction angiography in the workup of living renal donors. CONCLUSION Contrast-enhanced MR angiography for the preoperative evaluation of renal donors is superior to digital subtraction angiography in revealing vascular ...

Radiologic procedures used to evaluate patients with suspected glomus tumor have included plain skull radiography, temporal bone tomography, computed tomography, and cerebral angiography. Of these, only angiography has proven reliable as a screening procedure for small glomus tympanicum and jugulare tumors. Digital subtraction angiography was used as the initial examination for suspected paraga...
