Digital subtraction angiography apparatus.
Radiology, 1985An inexpensive digital subtraction angiography (DSA) apparatus that can perform live subtraction, processed subtraction, and road mapping is described. The apparatus can be used in any standard x-ray room with fluoroscopic capability, with a simple connection to the existing TV chain. It is especially useful in therapeutic neuroangiography.

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 ...

Clinical Radiology, 1998
Recent advances in angiography equipment have allowed the development of rotational digital subtraction carotid angiography. We give the first description of this technique applied to the extracranial carotid circulation, using the Phillips Integris V3000 release 11.

Digital Subtraction Angiography in Takayasu Arteritis
Acta Radiologica, 1987The usefulness and limitation of digital subtraction angiography (DSA) in Takayasu arteritis were investigated in 32 patients. Intravenous DSA was particularly useful in the follow-up of patients with an established diagnosis of Takayasu arteritis. Pulmonary arterial involvement could also be demonstrated with intravenous DSA as obstructive arterial ...

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 in the evaluation of hypertension
American Journal of Roentgenology, 1983Thirty-five patients with high blood pressure underwent digital intravenous subtraction angiography (DSA) for evaluation of renovascular disease. Eight had recurrent hypertension after renal transplantation, and four after aortorenal bypass. Twenty-three had DSA as part of a hypertensive screening workup for renovascular disease.

Digital subtraction angiography: The intravenous approach
International Journal of Cardiac Imaging, 1988With further improvement of digital subtraction angiography (DSA) equipment, and the development of sophisticated soft-ware programs, the intravenous approach again has become an promising diagnostic alternative in certain clinical settings, if the patient's cardiac output is not severely diminished.
