Comparison of white blood and black blood T2* cardiovascular magnetic resonance at 3 Tesla
نویسندگان
چکیده
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 BB and WB T2* iron measurement at 3T and compared results with corresponding 1.5T measurements.

Value of black blood T2* cardiovascular magnetic resonance
PURPOSE To assess whether black blood T2* cardiovascular magnetic resonance is superior to conventional white blood imaging of cardiac iron in patients with thalassaemia major (TM). MATERIALS AND METHODS We performed both conventional white blood and black blood T2* CMR sequences in 100 TM patients to determine intra and inter-observer variability and presence of artefacts. In 23 patients, 2 ...
متن کاملMyocardial iron assessment by T2* cardiovascular magnetic resonance at 3 Tesla
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 ...
متن کاملComparison of Magnetic Resonance Imaging T2 Results in Beta-Thalassemia Patients Treated by Deferasirox or Combination of Deferoxamine and Deferiprone
Background: Iron extra load is an anticipated and lethal consequence of chronic blood transfusion in major beta-thalassemia patients; therefore it is necessary to use an efficient iron chelator drug to stimulate the evacuation of the surplus iron from the body. This trial was performed to compare myocardial and hepatic magnetic resonance imaging T2 (MRI T2*) results of beta-thalassemia patients...
متن کاملMyocardial 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...
متن کاملCombining extracellular volume fraction imaging and T2 quantification by cardiovascular magnetic resonance in patients with clinically suspected myocarditis
Methods Short-axis T1 and T2 mapping were implemented into a standard CMR protocol at 1.5 Tesla in 36 patients with clinically suspected myocarditis. T1 quantification was performed for ECV calculation using the modified Look-Locker inversion-recovery (MOLLI) sequence before and 15 minutes after administration of 0.075 mmol/kg gadolinium BOPTA. T2 quantification was performed using a free-breat...
