Digital subtraction pulmonary angiography [PDF]
American Journal of Roentgenology, 1982 Digital 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 ...

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.

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 ...

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.

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 ...

Image noise reduction algorithm for digital subtraction angiography: clinical results.
Radiology, 2013PURPOSE To test the hypothesis that an image noise reduction algorithm designed for digital subtraction angiography (DSA) in interventional neuroradiology enables a reduction in the patient entrance dose by a factor of 4 while maintaining image quality.
