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 of the Kidney
British Journal of Urology, 1988Summary— Intravenous and intra‐arterial digital subtraction angiography (DSA) was performed in 88 patients: 34 with tumours, 10 with renal trauma, 26 with suspected renovascular hypertension, 6 with vascular impression on the renal pelvis, 8 with nephrolithiasis and 4 with sonographically abnormal kidneys.

Intravenous Digital Subtraction Angiography
Archives of Neurology, 1986To the Editor. —We welcome the cautionary note of Ball et al 1 concerning the use of intravenous (IV) digital subtraction angiography (DSA), but we believe that their conclusion that this procedure is more dangerous than standard angiography is not justified, since their two groups are not comparable.

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 Angiography
Medical Clinics of North America, 1986Digital subtraction angiography is a new imaging technique that uses a computer to subtract background distractions and to enhance contrast and density. The intravenous administration of contrast material permits safe outpatient screening for arterial disease.

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 ...

Cardiac applications of digital subtraction angiography [PDF]
The International Journal of Cardiac Imaging, 1985 Recent developments in digital computer technology have enabled direct digital acquisition of radiographic images at spatial and temporal resolutions similar to that of cineradiography. Initially intended as a means of performing peripheral angiography, digital subtraction angiography has been increasingly applied to cardiac catheterization procedures.

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.

Digital Subtraction Angiography
2019Despite the continued refinement of vascular ultrasound and noninvasive cross-sectional imaging studies (computed tomography angiography [CTA] and magnetic resonance angiography [MRA]) in the diagnosis of vascular pathologies, digital subtraction angiography (DSA) remains the “workhorse” imaging modality for the diagnosis and management of peripheral ...

Pediatric digital subtraction angiography.
Radiology, 1984Experience with intravenous digital subtraction angiography (DSA) in infants and children is limited, although its relative ease of performance, low complication rate, and diagnostic accuracy indicate great potential. We performed 87 DSA examinations (74 patients) and obtained sufficient detail to facilitate diagnosis in most cases.
