EXAMINING TECHNIQUE WITH DIGITAL SUBTRACTION ANGIOGRAPHY (DSA) IN ISCHEMIC HEART DISEASE

Progress in Cerebrovascular Disease Digital Subtraction Angiography in Cerebrovascular Disease

THE INTRAVENOUS INJECTION of contrast medi­ um for the visualization of vascular structures was introduced 43 years ago by Robb and Steinberg. This technique never gained widespread popularity because of the technical problems in obtaining consistent im­ ages of good quality. Also, the amount of contrast medium that had to be injected to achieve adequate visualization of large arteries was subs...

Digital subtraction angiography in infants and children with congenital heart disease.

Digital subtraction angiography was used as the sole imaging technique in 95 infants and children aged 13 hours to 16 years undergoing cardiac catheterisation for the investigation of congenital heart disease. Injections of diluted contrast medium were made selectively at central sites, and the images were obtained using continuous image intensification fluoroscopy at either 32.25 nC/kg/s (125 ...

MR Digital Subtraction Angiography

Analysis of Subtraction Methods in 3D Contrast-Enhanced MR Digital Subtraction Angiography Yuexi Huang Master of Science 2001 Department of Medical Biophysics University of Toronto 3D Contrast-enhanced MR angiography is promising as a replacement to catheter-based x-ray angiography due to its non-invasive nature. However, the image quality of MR angiography is still inferior to that of x-ray an...

Minimally Invasive Monitoring of Chronic Central Venous Catheter Patency in Mice Using Digital Subtraction Angiography (DSA)

BACKGROUND Repetitive administration of medication or contrast agents is frequently performed in mice. The introduction of vascular access mini-ports (VAMP) for mice allows long-term vascular catheterization, hereby eliminating the need for repeated vessel puncture. With catheter occlusion being the most commonly reported complication of chronic jugular vein catheterization, we tested whether d...
