Digital Subtraction Angiography
Scottish Medical Journal, 1987Digital Subtraction is a computerised radiological technique to demonstrate the vascular tree by removing unwanted background information and enhancing dilute contrast medium within the blood vessels. Contrast may be introduced intravenously or intra-arterially.

Digital Subtraction Angiography
The American Journal of Nursing, 1982Digital subtraction angiography (DSA), utilizing computerized x-ray imaging equipment for image acquisition and subtraction, will provide substantial improvements in blood vessel imaging. With the high contrast sensitivity of these systems, visualization of major blood vessels using intravenous injections of radiographic contrast media is possible on a

Pulmonary digital subtraction angiography
Cardiovascular and Interventional Radiology, 1983Intravenous digital subtraction pulmonary angiography was performed in 220 patients. Of these, 206 had suspected pulmonary embolism. Our intravenous studies yielded images of diagnostic quality in 98% of cases. Compared to conventional pulmonary angiography, intravenous digital subtraction angiography (IV DSA) is safer, faster, and easier to perform ...

Digital subtraction pulmonary angiography
American Journal of Roentgenology, 1982Digital subtraction pulmonary angiography was performed in 14 patients suspected of having pulmonary embolism. In 13 of 14, useful clinical information was obtained. Four patients were found to have pulmonary emboli. In nine patients, digital subtraction angiography was performed through pulmonary artery catheters already in place for monitoring ...

Biplane digital subtraction angiography
Computerized Radiology, 1986Biplane digital subtraction angiography was performed by placing a rapid switch between the anteroposterior and lateral T.V. cameras and the A-D converter. Alternate exposures from two X-ray tubes were employed. Excellent anteroposterior and lateral DSA was obtained especially for the brain and neck.

Intravenous Digital Subtraction Angiography
Neurosurgery, 1981Intravenous digital subtraction angiography (DSA) was used to evaluate the extracranial and/or intracranial arteries of 87 patients with suspected cerebrovascular disorders. The examinations were performed on either an inpatient or an outpatient basis. Renografin-76 was injected into an arm vein through an angiocatheter.

Pulmonary Digital Subtraction Angiography
Radiologic Clinics of North America, 1985Pulmonary angiography using intravenous rather than intra-arterial injections and digital subtraction technique provides an alternative to dependence on clinical impression, lung scans, and the more invasive transcardiac selective pulmonary angiogram for the diagnosis of pulmonary embolism. However, successful studies of the pulmonary circulation using

Renal digital subtraction angiography
Cardiovascular and Interventional Radiology, 1983Digital subtraction angiography (DSA), a new computer-assisted radiographic procedure, has recently been applied to the evaluation of the kidney and in the screening of patients with renal vascular hypertension. The efficacy of the method in the evaluation of the anatomy of proximal renal arteries is in the 80-90% range; however, DSA is less effective ...

Renal Digital Subtraction Angiography
Urologic Clinics of North America, 1985Renal digital imaging has progressed rapidly in reliability and potential since its clinical introduction in 1979. The advent of larger image intensifiers has made feasible subtraction imaging of the renal parenchyma and collecting systems as an adjunct to IV-DSA.
