Contrast-enhanced magnetic resonance cholangiography with Gd-BOPTA and Gd-EOB-DTPA in healthy subjects.
PURPOSE To evaluate the biliary enhancement dynamics of the two gadolinium chelates Gd-BOPTA (MultiHance) and Gd-EOB-DTPA (Primovist) in normal healthy subjects. MATERIAL AND METHODS Ten healthy volunteers were evaluated with both agents by magnetic resonance (MR) imaging at 1.5T using a breath-hold gradient-echo T1-weighted VIBE sequence. The relative signal intensity (SI) differences betwee...
متن کاملQuantitative Evaluation of Contrast Agent Dynamics in Liver MRI
Published articles have been reprinted with the permission of the copyright holder. Abstract ABSTRACT The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients. Ten healthy volunteers were examined with both co...
متن کاملFlip angle Optimization with Hepatobiliary Contrast Agents at 3T
INTRODUCTION: To date, two FDA-approved Gadolinium-based contrast agents Gd-EOBDTPA (Gadoxetate, Eovist, Bayer Pharmaceuticals, Wayne, NJ), and Gd-BOPTA (Gadobenate, Bracco Diagnostics, Princeton, NJ) are available for hepatobiliary imaging. The pharmacokinetics of these agents are different, with approximately 4-5% hepatic uptake with Gd-BOPTA at 1-2 hours, and 50% uptake of Gd-EOB-DTPA at app...
متن کاملFocal hepatic lesions in Gd-EOB-DTPA enhanced MRI: the atlas
OBJECTIVE This article reviews the different technical aspects and pitfalls of gadolinium (Gd)-ethoxibenzyl (EOB)-diethylenetriamine pentaacetic acid (DTPA) and the advantages of the hepatocellular phase (HCP) and defines its specific imaging features of liver lesions. BACKGROUND Gd-EOB-DTPA is a contrast agent with combined properties of a conventional non-specific extracellular and a hepato...
متن کاملContrast uptake in primary hepatic angiosarcoma on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging in the hepatobiliary phase
Primary hepatic angiosarcoma is the most common malignant mesenchymal tumor of the liver. It has a poor prognosis and various appearances on magnetic resonance (MR) images. We report a case of hepatic angiosarcoma with a characteristic appearance on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MR imaging in the hepatobiliary phase. A 72-year-old man was adm...
