Comments, Opinions, and Reviews Digital Subtraction Angiography: Current Clinical Applications
نویسنده
چکیده
The applications of digital subtraction angiography (DSA) in neurologic diagnosis have been evolving as clinical experience with this technology accumulates. Initial enthusiasm with the intravenous contrast material injections has been tempered by often equivocal results. Intravenous DSA (IV-DSA) is still an accurate screening technique for extracranial carotid atherosclerosis, comparable to duplex ultrasound. Intracranial imaging is less satisfying with intravenous injections but reliable information is available in the assessment of the venous sinuses and parasellar internal arteries. The future of DSA lies with intraarterial contrast injections, as this technique substantially decreases the risks and costs of definitive cerebrovascular investigation.

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 ...
متن کاملIntracranial vessel wall imaging: current applications and clinical implications
Conventional CT, MR, and digital subtraction angiography rely on the presence of luminal narrowing for the identification of vascular pathology offering limited insight into the offending pathophysiologic mechanism affecting the vessel. High-resolution MRI vessel wall imaging (VWI) has the potential to directly depict and characterize vessel wall pathology affecting the intracranial circulation...

We address the problem of motion artifact reduction in digital subtraction angiography (DSA) using image registration techniques. Most of registration algorithms proposed for application in DSA, have been designed for peripheral and cerebral angiography images in which we mainly deal with global rigid motions. These algorithms did not yield good results when applied to coronary angiography imag...

A case is presented in which the detection of venous-stasis retinopathy in one eye led to investigation of the carotid circulation. There were no neurologic symptoms of carotid insufficiency, and noninvasive tests failed to reveal significant carotid pathology. Digital subtraction angiography and carotid angiography demonstrated a carotid plaque of doubtful significance. At carotid endarterecto...
متن کاملNeuroradiologic 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.
