Angiography Using Kinetic Imaging – A Comparison to Digital Subtraction Angiography

3D cerebral angiography: radiation dose comparison with digital subtraction angiography.

BACKGROUND AND PURPOSE As the use of 3D rotational angiography (3D RA) for the evaluation of cerebral vasculature becomes more widespread, it is important to evaluate this imaging method's effect on patient radiation dose. The purpose of the study is to measure 3D RA radiation dose as compared with biplanar digital subtraction angiography (DSA). METHODS The distribution and peak skin dose wer...

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...

Intravenous angiography using digital video subtraction: intravenous cervicocerebrovascular angiography.

The clinical application of intravenous angiography to study the cervicocerebrovascular system using the digital video subtraction system described in a companion article is reported. About 0.75 ml/kg of a standard 76% iodine contrast solution is injected into an antecubital vein using a power injector. Then 15-20 exposures of the head and neck region at a 1/sec rate are made on the image inten...

Digital subtraction angiography.

Intravenous angiography using digital video subtraction: x-ray imaging system.

An x-ray imaging system, using digital subtraction techniques, has been developed. The system requires: (1) high output generation equipment; (2) an image intensifier capable of receiving high output exposures, 1 mR (2.58 X 10(-7) C/kg) at the face of the intensifier, without loss of either contrast or resolution; (3) a precision digital video camera; (4) processing computer with sufficient sto...
