Low T2-star (T2*) Signals in cardiac MR imaging in patients with dilated cardiomyopathy and sarcoidosis
Methods We enrolled 11 non-cardiomyopathic and 93 cardiomyopathic patients with following diagnoses: hypertensive or hypertrophic cardiomyopathy (n=22), dilated cardiomyopathy (n=28), sarcoidosis (n=13), old myocardial infarction (n=7), and other form of cardiomyopathy (n=23). Using 3-Teslar cardiac MRI (SignaHDxt, GE medical), T2* signal intensity in the cardiac ventricular septum and hepatic ...
متن کاملAssociation between serum ferritin level, cardiac and hepatic T2-star MRI in patients with major β-thalassemia
Background Frequent blood transfusion is often associated with iron overload. Proper use of iron chelators to treat iron overload requires an accurate measurement of iron levels. Magnetic resonance T2-star (T2* MRI) can measure iron level in the heart and liver. Our goal was to see whether an association exists between serum ferritin level and T2* MRI in patients with major beta thalassemia. ...
متن کاملCardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging
Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...
متن کاملCardiac iron determines cardiac T2*, T2, and T1 in the gerbil model of iron cardiomyopathy.
BACKGROUND Transfusional therapy for thalassemia major and sickle cell disease can lead to iron deposition and damage to the heart, liver, and endocrine organs. Iron causes the MRI parameters T1, T2, and T2* to shorten in these organs, which creates a potential mechanism for iron quantification. However, because of the danger and variability of cardiac biopsy, tissue validation of cardiac iron ...
متن کاملT2-star (T2*) magnetic resonance imaging for assessment of kidney iron overload in thalassemic patients.
BACKGROUND Improved survival in thalassemic patients has lead to the manifestation of morbidities such as renal dysfunction. This involvement suggests the need for a reliable and non-invasive method to assess the degree of kidney iron overload. We conducted the present study to evaluate the relationship between serum ferritin levels, liver, heart, and kidney MRI gradient echo (T2*) relaxation t...
