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...
متن کامل3D 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...
متن کاملApplication of ICA to X-ray coronary digital subtraction angiography
In this paper, an effective method is developed to extract coronary vessels from X-ray digital subtraction angiography (DSA). Unlike the traditional image subtraction technique, we used the independent component analysis (ICA) to separate the coronary vessels and backgrounds. Experimental results indicate that the proposed method can achieve better performance than the traditional & 2011 Elsevi...
متن کاملApplication of Time-Resolved 3D Digital Subtraction Angiography to Plan Cerebral Arteriovenous Malformation Radiosurgery.
BACKGROUND AND PURPOSE Time-resolved 3D-DSA (4D-DSA) enables viewing vasculature from any desired angle and time frame. We investigated whether these advantages may facilitate treatment planning and the feasibility of using 4D-DSA as a single imaging technique in AVM/dural arteriovenous fistula radiosurgery. MATERIALS AND METHODS Twenty consecutive patients (8 dural arteriovenous fistulas and...
متن کاملMR digital subtraction angiography of cerebral arteriovenous malformations.
BACKGROUND AND PURPOSE Although phase-contrast MR angiography provides some information regarding hemodynamics of cerebral arteriovenous malformations (AVMs), most conventional MR angiographic techniques have not been helpful in this respect. We attempted to determine the value of MR digital subtraction angiography (DSA) in assessing AVM hemodynamics. METHODS We developed an MR DSA technique ...
