Carotid-cavernous fistulas: diagnosis with spiral CT angiography.
Four cases in which the diagnosis of carotid-cavernous fistula was made by using CT angiography are illustrated. The diagnosis was confirmed by digital subtraction angiography in all four instances. To our knowledge, this is the first report of the CT angiographic appearance of carotid-cavernous fistulas.
متن کاملNoninvasive coronary angiography by retrospectively ECG-gated multislice spiral CT.
BACKGROUND We investigated the applicability and image quality of contrast-enhanced coronary artery visualization by multislice spiral CT using retrospective ECG gating. METHODS AND RESULTS Twenty-five patients in sinus rhythm (significant coronary artery stenoses ruled out by invasive angiography) were studied with a multislice spiral CT (Siemens SOMATOM Volume Zoom). In inspiration (mean br...
متن کاملSpiral CT angiography and selective digital subtraction angiography of internal carotid artery stenosis.
PURPOSE To determine whether spiral CT angiography allows accurate, quantitative evaluation of anatomic abnormalities, including detection of additional lesions, delineation of plaque morphology, and estimation of degree of internal carotid artery stenosis. METHODS Spiral CT angiography with a maximum intensity projection technique was compared with selective digital subtraction angiography (...
متن کاملProspective-triggered high-pitch spiral versus sequential dual-source CT coronary angiography: comparison of image quality and radiation dose
Background: Prospectively electrocardiography (ECG)-triggered high-pitch spiral coronary computed tomography angiography (CCTA) is a unique scan mode for dual-source CT (DSCT). Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates. Materials and Methods: Patients with low and stable ...
متن کاملA comparison study between CT angiography with 64-multislice spiral computed tomography and selective X-ray coronary angiography
The aim of this study was to evaluate the diagnostic value of 64-multislice spiral computed tomography (64-MSCT) for coronary stenosis compared with selective X-ray coronary angiography (SCA). Patients with chest pain, chest tightness or coronary stenosis received SCA and they acted as the controls. The sensitivity and accuracy of 64-MSCT were analyzed as compared with SCA. Images from 64-MSCT ...
