Low T2-star (T2*) Signals in cardiac MR imaging in patients with dilated cardiomyopathy and sarcoidosis

چکیده
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 parenchyma were measured.

Evaluation of tissue doppler echocardiography and T2* magnetic resonance imaging in iron load of patients with thalassemia major
Background: Iron-mediated cardiomyopathy is the main complication of thalassemia major (TM) patients. Therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. The aim of this study was to evaluate the efficacy of tissue doppler imaging (TDI) to study cardiac iron overload in patients with TM using T2* magnetic resonance (MR) as the gold-standard...
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 کاملCardiovascular magnetic resonance T2 mapping detects myocardial edema in patients with chronic dilated cardiomyopathy
Background Global myocardial edema, a surrogate measure of myocardial inflammation, has been reported in patients with chronic dilated cardiomyopathy (DCM) based on T2weighted STIR imaging. However, STIR imaging is prone to motion artefact and issues related to cardiac cycle timing and coil sensitivity. We hypothesised that a novel quantitative CMR T2 mapping technique would provide a reliable ...

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 کاملThe value of myocardial perfusion imaging in differentiating between idiopathic dilated cardiomyopathy from the ischemic form [Persian]
Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...
