متن کاملQuantitative Evaluation of Liver Function with MRI Using Gd-EOB-DTPA
OBJECTIVE Gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) is a newly developed MR contrast agent. After intravenous injection, Gd-EOB-DTPA is gradually taken up by the hepatocytes and eventually excreted via the biliary pathway without any change to its chemical structure. Because of these characteristics, it can be used as a tracer for quantitative liver function testi...
متن کاملMyocardial Perfusion Quantification Using Dynamic MRI and Gd-DTPA in Patients after PTCA and Brachytherapy
Introduction The identification of viable myocardium in patients with infarct who are likely to benefit from revascularization is mainly based on PET and other radionuclide imaging modalities. A recent study suggested the value of delayed MRI contrast enhancement for the exclusion of viability (1). However, early imaging after contrast injection with MR using first pass technique contains also ...
متن کاملDual Echo Dynamic MRI using Dy- micelles and Gd-DTPA as a contrast agent
Introduction: Dynamic contrast enhanced MRI can examine tissue vascularization but cannot distinguish between perfusion and permeability effects. By injecting Gd-DTPA (extravascular contrast agent) concurrently with Dy-micelles (intravascular within the imaging time frame) and imaging them at different echo times, it might be possible to estimate both perfusion and permeability parameters simul...
متن کاملQuantitative Evaluation of Enhancement Patterns in Focal Solid Liver Lesions with Gd-EOB-DTPA-Enhanced MRI
PURPOSE The objective was to investigate the dynamic enhancement patterns in focal solid liver lesions after the administration of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) by means of dynamic magnetic resonance imaging (MRI) including hepatobiliary phase (HP) images 20 min after Gd-EOB-DTPA administration. MATERIALS AND METHODS Non-enhanced T1/T2-weighted as w...
