Myocardial iron assessment by T2* cardiovascular magnetic resonance at 3 Tesla

چکیده
Background Chronic iron overload is prevalent and prognosis relates to the severity of cardiac siderosis. The black blood (BB) T2* technique is validated, with calibration against myocardial tissue iron at 1.5T. There are potential advantages of 3T over 1.5T in assessing T2*, but preliminary studies at 3T used white blood imaging, had small patient numbers, methodological differences, and poor signal-noise ratio in severe iron overload precluding assessment across a wide dynamic range. A novel noise correction (NC) algorithm is superior to other techniques in severe iron loading. We assessed BB T2* iron measurement at 3T against the 1.5T gold standard and incorporated the NC algorithm.

Myocardial iron assessment by T1 cardiovascular magnetic resonance at 1.5 Tesla
Background Heart failure secondary to cardiac siderosis is the prevalent cause of mortality in patients with primary or secondary iron overload. Myocardial iron assessment using T2* has been successfully calibrated against myocardial iron at 1.5T and the black blood (BB) technique has demonstrated high reproducibility such that it has become the clinical gold standard. T1 appears to correlate w...

Background T2* relaxometry offers a non-invasive method to accurately quantify myocardial iron levels, thus aiding the diagnosis and assessment of prognosis of patients. Two T2* sequences are used clinically: the single breathhold multi-echo gradient echo white blood (WB) and black blood (BB) techniques. At 1.5T, BB T2* has superior reproducibility and fewer artefacts than WB T2*. We compared B...
متن کاملMyocardial T2 quantitation in patients with iron overload at 3 Tesla.
PURPOSE To investigate the feasibility of measuring myocardial T2 at 3 Tesla for assessment of tissue iron in thalassemia major and other iron overloaded patients. MATERIALS AND METHODS A single-breathhold electrocardiogram-triggered black-blood multi-echo spin-echo (MESE) sequence with a turbo factor of 2 was implemented at 3 Tesla (T). Myocardial and liver T2 values were measured with three...
متن کاملMyocardial iron assessment by T1 cardiovascular magnetic resonance at 3 Tesla
Background Myocardial T2* relaxometry at 1.5T provides reliable non-invasive assessment of cardiac iron burden and is commonly used for the diagnosis and monitoring of patients at risk. 3T CMR offers some advantages over 1.5T but iron assessment has not been routinely performed at 3T due to technical concerns regarding artefacts and rapid signal loss, as well as a lack of tissue calibration. In...
متن کاملEvaluation 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...
