Rotational angiography assessment of cerebral aneurysms.
PURPOSE To compare rotational angiography with conventional digital subtraction angiography in the assessment of cerebral aneurysms. METHODS Conventional digital subtraction angiography and rotational angiography were compared in 57 patients investigated for the preoperative diagnosis of subarachnoid hemorrhage and in 13 patients after surgery. Images were compared for location, visibility of...
متن کاملRotational cerebral angiography: procedure and value.
Rotational cerebral angiography provides continuously changing projections and correspondingly excellent visualization of aneurysms or other vascular malformations requiring special or oblique views. Rotation angiography as part of the routine angiography gives a three-dimensional impression with one injection and series of films. Although additional subtraction technique is not possible and th...
متن کاملDigital subtraction rotational angiography for aneurysms of the intracranial anterior circulation: injection method and optimization.
PURPOSE To optimize parameters of rotational angiography for examination of the internal carotid circulation; to compare rotational angiography with standard digital subtraction angiography (DSA) in the evaluation of aneurysms of the intracranial internal carotid circulation; and to determine tolerance and safety limits of prolonged internal carotid injection angiography. METHODS Rotational a...
متن کاملA method for 3D reconstruction of coronary arteries using biplane angiography and intravascular ultrasound images.
The aim of this study is to describe a new method for the three-dimensional reconstruction of coronary arteries and its quantitative validation. Our approach is based on the fusion of the data provided by intravascular ultrasound images (IVUS) and biplane angiographies. A specific segmentation algorithm is used for the detection of the regions of interest in intravascular ultrasound images. A n...
متن کامل3D Reconstruction of Coronary Artery using Biplane Angiography
In this paper, we present a new method for the 3D reconstruction and visualization of coronary arteries in biplane angiography. The proposed method performs direct reconstruction of 3D coronary artery pathways without computing the 2D or 3D vessel centerlines. A front propagation algorithm is used to reconstruct the coronary artery pathways in 3D space. Starting from one or more 3D points, the ...
