Detection of coronary stenoses with contrast enhanced, three-dimensional free breathing coronary MR angiography using the gadolinium-based intravascular contrast agent gadocoletic acid (B-22956).
PURPOSE To determine the diagnostic value of the intravascular contrast agent gadocoletic acid (B-22956) in three-dimensional, free breathing coronary magnetic resonance angiography (MRA) for stenosis detection in patients with suspected or known coronary artery disease. METHODS Eighteen patients underwent three-dimensional, free breathing coronary MRA of the left and right coronary system be...
متن کاملTriphasic Contrast Agent Injection in 64-MDCT Coronary Artery Angiography
Purpose: To evaluate image quality and cardiovascular enhancement after triphasic injection in 64-slice-CT coronary angiography (c-CTA). Methods: c-CTA of twenty-two asymptomatic patients following triphasic injection (65ml-contrast bolus + mixed 30mlcontrast and 20ml-saline bolus + 50ml-saline chaser) were retrospectively reviewed. Attenuation in the great vessels, cardiac chambers, and corona...
متن کاملGadolinium-DTPA: A New Contrast Agent
Gadolinium (Gd)-DTPA-dimeglumine (tradename: Magnevist?) is the first commercially available contrast agent for magnetic resonance tomography (MRT). As a result of the very favourable results from preclinical and clinical investigations Magnevist? was granted a product license for cranial and spinal MRT in the Federal Republic of Germany in early February this year. Magnevist? is a paramagnetic...
متن کاملGadolinium as a contrast agent for NMR.
Gadolinium chloride (GdCl3) was studied as a contrast agent for nuclear magnetic resonance. This rare-earth element dramatically alters proton resonance (paramagnetic moment = 10.8 Bohr magnetons). Acute toxicity was determined by intravenous injections in mice; mean lethal dose was 100-200 mg of GdCl3 . 6 H2O/kg. Changes in T1 of plasma, kidney, liver, and brain of mice and rats were measured ...
متن کاملThree-dimensional magnetic resonance coronary angiography using a new blood pool contrast agent: initial experience.
OBJECTIVE The aim of this feasibility study was to assess the effect of a new blood pool contrast agent on magnetic resonance coronary angiography (MRCA) in patients suspected of having coronary artery disease. METHODS Nine patients referred for diagnostic x-ray coronary angiography in the evaluation of chest pain underwent MRCA using a thin-slab three-dimensional (3D) breath-hold segmented g...
