Flexible Mask Subtraction For Digital Angiography
SPIE Proceedings, 1988A flexible-mask algorithm that effectively provides correction for motion artifacts and gray-level variations in digital subtraction angiography (DSA) images is presented. The algorithm makes use of a flexible local registration of the mask with the live image to minimize the main distortions caused by the complex motion of the heart, namely spatial ...

Digital subtraction angiography of the aortic arch
Cardiovascular and Interventional Radiology, 1983We evaluated the utility of intravenous digital subtraction angiography (IV DSA) for diagnosing lesions of the aortic arch and great vessels in 25 patients. Digital subtraction angiography (DSA) was found useful in evaluating congenital and acquired lesions of the arch and great vessel origins, and it proved adequate for follow-up of patients who had ...

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.

Digital Subtraction Angiography of the Chest
Clinics in Chest Medicine, 1984Intravenous digital subtraction angiography has developed into a useful imaging technique for the evaluation of vascular abnormalities. It is less invasive than standard arteriography, requiring less time, expense, and technical expertise and, most importantly, lower patient morbidity.

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 ...

[Angiography and digital subtraction angiography].
Monatsschrift Kinderheilkunde : Organ der Deutschen Gesellschaft fur Kinderheilkunde, 1986In pediatrics angiography is a method that is used relatively rarely. During the last few years the introduction of nonionic contrast media has led to considerable progress in the field of conventional angiography since these contrast media are tolerated much better than the ionic ones.
