Quantification of severe liver iron overload using MRI offset echoes
Magnetic resonance imaging (MRI) has become the clinical standard to estimate liver iron overload. The most commonly used method is to measure the transversal relaxation time, T2*, from a multi gradient recalled echo sequence (MGRE). While this technique is reliable in low to moderate liver iron concentrations (LIC), it will be inaccurate when it is severe. We report a case with severe liver he...
متن کاملAssessment of Pancreatic Iron Overload in Transfusion Dependent Thalassemic Patients
Advances in the management of transfusion dependent thalassemic patients have improved the survival of these patients. The most important consequence of repeated and frequent transfusions is iron accumulation in vital organs. The magnetic resonance imaging (MRI) is a non-invasive and valid technique for the estimation of iron stores. Despite multiple studies about cardiac and liver MRI T2*, the...
متن کاملAssessment of Organ Specific Iron Overload in Transfusion-dependent Thalassemia by Magnetic Resonance Imaging Techniques
The consequence of repeated blood transfusions in thalassemia is iron overload in different organs. Magnetic resonance imaging (MRI) is a reliable, non-invasive and accurate method for iron detection in various tissues, hence the introduction of MRI has revolutionized the management of these patients and improved the life expectancy of them. Cardiac MRI T2* has a profound effect not only on est...
متن کاملMRI assessment of changes in liver iron deposition post-venesection.
OBJECTIVE The aim of this study was to determine if changes in hepatic iron content in patients with hemochromatosis pre- and post-venesection could be detected by changes in liver signal intensity with MRI. MATERIALS AND METHODS The study was performed with institutional ethics approval and with informed consent. Gradient echo images were performed on 20 patients with hemochromatosis pre- an...
متن کاملNon-invasive assessment of tissue iron overload.
In recent years, there has been increasing interest in non-invasive iron measurement, especially of the liver and heart, in patients with iron overload. Serum ferritin still remains an essential monitoring parameter in intervals between liver iron measurements; however, confounding factors such as inflammation, chelation treatment changes and the specific disease have to be taken into account. ...
