Dual 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 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 کاملPrediction of Microvascular Invasion in Hepatocellular Carcinoma: Preoperative Gd-EOB-DTPA-Dynamic Enhanced MRI and Histopathological Correlation
Objective To investigate the imaging features observed in preoperative Gd-EOB-DTPA-dynamic enhanced MRI and correlated with the presence of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) patients. Methods 66 HCCs in 60 patients with preoperative Gd-EOB-DTPA-dynamic enhanced MRI were retrospectively analyzed. Features including tumor size, signal homogeneity, tumor capsule, tum...
متن کاملGd-EOB-DTPA combined with Gd-DTPA: Hepatobiliary contrast with familiar hepatic dynamic contrast enhancement
PURPOSE: Hepatobiliary contrast agents add an additional form of image contrast to hepatic magnetic resonance (MR) imaging, allowing differentiation of tumors which have functional hepatic and biliary components from those without. Gd-EOB-DTPA has sufficiently significant elimination via the hepatobiliary pathway to make it a feasible contrast agent in the time allotted to a typical clinical ab...
متن کاملDiagnostic Value of Gd-EOB-DTPA-MRI for Hepatocellular Adenoma: A Meta-Analysis
Objective: This study aimed to systematically review the gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-MRI) findings of hepatocellular adenoma (HCA), especially focusing on the diagnostic value of low signal intensity (SI) in the hepatocyte-phase (HBP) for differentiating HCA from focal nodular hyperplasia (FNH). Methods: A thorough literature search was conducted in PubMed, E...
