R2* Quantification of High Iron Concentrations for Cellular Therapy Applications with TurboSPI
Introduction: Many MRI techniques are now capable of imaging cells that have been labelled with super-paramagnetic iron oxide (SPIO) [1], and these techniques will be of great benefit to the developing field of cellular therapy. However, the majority of these techniques are not capable of providing quantitative information about cellular density at high iron concentrations, which is critical to...
متن کاملR2* for myocardial iron quantification at 3T CMR using an advanced shimming algorithm
Background Quantification of myocardial iron overload is critical for the management of patients with hemochromatosis. T2* relaxation time or its inverse R2*, are currently the noninvasive gold standard at 1.5T, as they strongly correlate with myocardial iron concentration, and are obtained using a fast single breath-hold ECG-gated multi-echo GRE sequence. However, due to high sensitivity to B0...
متن کاملR2* as a surrogate measure of ferriscan iron quantification in thalassemia.
PURPOSE To determine whether R2* values are a consistent predictor of hepatic iron concentration (HIC) in thalassemia patients by demonstrating a correlation between R2* relaxation rates and FerriScan-determined HIC. MATERIALS AND METHODS Eighty-eight patients with thalassemia major were retrospectively evaluated. All patients underwent FerriScan imaging and multiecho gradient echo imaging. T...
متن کاملA Comparison Study of Liver R2* Measurement in Pediatric Patients with Iron Overload
INTRODUCTION Iron overload is a common occurrence in children with thalassaemia major and sickle cell disease (due to frequent blood transfusions) or hereditary hemochromatosis. In this patient group, a non-invasive means to quantify iron is extremely attractive compared to conventional liver biopsy for determining total body iron. Recent advances in MRI have enabled non-invasive iron quantific...
متن کاملMagnetic resonance elastography of liver in healthy Asians: normal liver stiffness quantification and reproducibility assessment.
PURPOSE To determine normal liver stiffness values evaluated with magnetic resonance elastography (MRE) in healthy normal Asian volunteers and assess its reproducibility. MATERIALS AND METHODS Liver stiffness was evaluated with MRE in 41 healthy Asians (23 females, 18 males; mean age, 41.8 years, and mean body mass index [BMI], 23.4 kg/m(2) ) on a 1.5T clinical scanner. The correlations betwe...
