Digital subtraction angiography in cerebrovascular 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 for hemodynamic evaluation of cerebrovascular reconstructive surgery].

From May, 1982 to May, 1983, 300 consecutive patients were examined by intravenous digital subtraction angiography (DSA) using the Philips DVI system, which had a 512 X 512 matrix for video-imaging. Of those patients, 160 were diagnosed as having ischemic cerebrovascular disease. Attention was focused on 17 cases who were treated by a extracranial-intracranial (EC-IC) bypass and 5 cases treated...

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...
