Intracranial dural arteriovenous fistula successfully treated by combined open-endovascular procedure [PDF]

, 2010
Intracranial dural arteriovenous fistulas constitute a rare though potentially devastating disease. Because the arterial (high-pressure) blood flow drains directly into the low-pressure venous system, there is a high risk of bleeding and associated ...

Machine Learning Application With Quantitative Digital Subtraction Angiography for Detection of Hemorrhagic Brain Arteriovenous Malformations

IEEE Access, 2020
Clinical features are the primary measures used for risk assessment of cerebrovascular diseases. However, clinical features, especially angioarchitecture, in digital subtraction angiography require further interpretation by specialized radiologists. This

Imaging in the evaluation of renovascular disease [PDF]

, 2009
Renovascular disease (RVD) is an important cause of hypertension in children, as it often is amenable to potentially curative treatment. Imaging aimed at finding RVD therefore needs to have high sensitivity so as not to miss important findings.

Synchrotron radiation in radiology: radiology techniques based on synchrotron sources [PDF]

, 2018
The characteristics of synchrotron X-ray sources—quite different from those of conventional sources—are exploited by several new imaging techniques. These techniques expand the capabilities of conventional radiology and find interesting application in ...

Assessing the quality of angiographic display of brain blood vessels aneurysms compared to intraoperative state [PDF]

, 2013
Background/Aim. Aneurysms in brain blood vessels are expanding bags composed of a neck, body and fundus. Clear visibility of the neck, the position of the aneurysm and surrounding structures are necessary for a proper choice of methods for excluding ...
