Digital subtraction angiography: A review of cardiac applications

Digital subtraction angiography: a review of cardiac applications.

I MAGING OF the chambers of the heart, pulmonary circulation, and great vessels by intravenous (IV) contrast injection was clinically implemented as early as 1939.’ It was not until the achievement of relatively recent advances in digital electronics, image intensification, and television technology that a major resurgence of interest in this technique occurred. These technological advances in ...

Neuroradiologic applications of intraarterial digital subtraction angiography.

In the neuroradiologic evaluation of 118 patients using intraarterial digital subtraction angiography definite advantages and disadvantages were defined. Advantages include reduction of contrast medium volume, catheter time, and patient risk and discomfort. It also aids in angiographic planning. The paramount disadvantage is less spatial resolution compared with conventional film angiography.

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...

Intraoperative digital subtraction angiography: a review of 112 consecutive examinations.

PURPOSE To examine the effect of intraoperative angiography on neurosurgery and angiographic technical success, safety, and accuracy. METHODS Angiographic studies, surgical reports, and hospital records were reviewed retrospectively for 112 consecutive procedures in which intraoperative angiography was performed during neurosurgery. The results of conventional postoperative angiograms in 28 o...
