Copyright © 2021 Elsevier B.V. or its licensors or contributors. Matthew P. Armon. Spiral CT angiography is a new, minimally invasive technique for vascular imaging that is made possible by combining two recently developed techniques: slip-ring CT scanning and computerized three-dimensional (3D) reconstruction. The advent of Spiral Computed Tomographic (CT) angiography has provided the patients a non-invasive, accurate and fast modality of imaging the vasculature. 3, 11 July 2009 | Journal of Organ Dysfunction, Vol. Die CT-Angiographie basiert auf einem Multislice-CT (Mehrschicht-CT). 2, The Obstetrician & Gynaecologist, Vol. 70 Accesses. 188, No. It is safe both in terms of being non-invasive and exposure to radiation. 8, 29 January 2009 | The International Journal of Cardiovascular Imaging, Vol. There was no difference between spiral CT and angiography for detection of subsegmental-sized pulmonary emboli. 25, No. Both catheter and spiral computed tomography (CT) angiography of the lower extremity vasculature were performed in six patients with clinically symptomatic peripheral vascular disease. 10, 1 August 2007 | Radiology, Vol. They feature 64 slices and thinner detectors, and the x-ray tube permits higher x-ray output and faster tube rotation. ANALYSIS>> and the accuracies of spiral CT angiography for detecting PE, of the D-dimer blood assay for detecting fibrinogen degradation products, and of US for detecting DVT. 25, No. 38, No. The category of stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial: mild (0% to 29%), moderate (30% to 69%), severe (70% to 99%), and occlusion (100%). 27, No. Patients and method.

CT angiography has tremendous potential in imaging the intracranial vasculature. 226, No. 2, American Journal of Roentgenology, Vol. Using a spiral CT-scanner a volumetric scan was made during injection of 150 cc of i.v. Does pregnancy affect vascular enhancement in patients undergoing CT pulmonary angiography? Nowadays multidetector spiral CT angiography allows acquisition of large volumes displaying the whole abdominal aorta and inferior limbs arterial tree. 3, Korean Journal of Radiology, Vol. Sign In Create Free Account. Acute coronary syndrome due to high aortocoronary junction of the right coronary artery: the value of multislice CT. Int J Cardiol 2008; 123(3):e59-61. Critical Reviews in Oncology/Hematology, Vol. Yan Feng 1 and Sheng Jie Shu 1. Non-invasive coronary artery angiography by 16 multidetector-row spiral computed tomography is a novel diagnostic tool whose reliability is still unclear. The purpose of this essay is to illustrate the appearances of various normal and diseased vessels using this technique. We conclude that spiral CT is comparable to angiography for detection of pulmonary emboli. Diagnostic Value of Low-Dose 256-Slice Spiral CT Angiography, MR Angiography, and 3D-DSA in Cerebral Aneurysms. 7, Korean Journal of Radiology, Vol. The mean heart rate in these patients dropped within 45 minutes from 68.2 10.2 to 57.8 6.8 bpm. Neurosurgery 1995 ; 36: 320-7. 36, No. 4, 26 July 2007 | Emergency Radiology, Vol. Die Untersuchung bedient sich der modernen Mehrzeilen-Computertomographie. 29, No. 12, Current Problems in Surgery, Vol. Performing of CTA is possible after introduction of spiral CT technique whose characteristics are short imaging time and volumetric data acquisition. Matthew P. Armon, FRCS. It seems that a reduction of contrast medium volume will not degrade the image quality. Excellent demonstration and delineation of normal blood vessels arteriovenous malformations and aneurysms were acquired. 2, Korean Circulation Journal, Vol. A propósito de dos casos, Multislice CT in the Detection of Pulmonary Embolism, Multi–Detector Row Spiral CT Pulmonary Angiography: Comparison with Single–Detector Row Spiral CT1, Sonography of Lung and Pleura in Pulmonary Embolism, NEWER DIAGNOSTIC MODALITIES FOR PULMONARY EMBOLISM, Cardiovascular Abnormalities Incidentally Detected on Helical CT Pulmonary Angiography: Spectrum of Findings, Multi–Detector Row CT of Thoracic Disease with Emphasis on 3D Volume Rendering and CT Angiography1, CT Pulmonary Angiography with a Macromolecular Contrast Medium, Idiopathic pulmonary artery aneurysm: Digital subtraction pulmonary angiography grossly underestimates the size of the aneurysm, Pulmonary arteriovenous malformation: Characterization with time-resolved ultrafast 3D MR angiography, Techniques for performing multidetector-row computed tomographic angiography, 3D CT angiography in patients before and after liver transplantation, Diagnosis of Pulmonary Embolism With Use of Computed Tomographic Angiography, Anomalous Unilateral Single Pulmonary Vein, Pulmonary arteriovenous malformations: Transcatheter embolization options.
