Validation of Siemens T2* inline WIP package for quantification of cardiac and hepatic iron loading at 1.5T and 3T
نویسندگان
چکیده
Background The ability of T2* cardiovascular magnetic resonance (CMR) to identify cardiac iron loading has facilitated a dramatic reduction in mortality in patients with iron overload. There remains a worldwide need for improved access to iron evaluation. One route to achieving this would be simple in-line T2* analysis. We compared our validated T2* methods which use Royal Brompton Hospital (RBH) T2* sequences with analysis by CMRtools against a novel work-in-progress (WIP) sequence and inline T2* analysis.

T1 at 1.5T and 3T compared with conventional T2* at 1.5T for cardiac siderosis
BACKGROUND Myocardial black blood (BB) T2* relaxometry at 1.5T provides robust, reproducible and calibrated non-invasive assessment of cardiac iron burden. In vitro data has shown that like T2*, novel native Modified Look-Locker Inversion recovery (MOLLI) T1 shortens with increasing tissue iron. The relative merits of T1 and T2* are largely unexplored. We compared the established 1.5T BB T2* te...

BACKGROUND There is a need for improved worldwide access to tissue iron quantification using T2* cardiovascular magnetic resonance (CMR). One route to facilitate this would be simple in-line T2* analysis widely available on MR scanners. We therefore compared our clinically validated and established T2* method at Royal Brompton Hospital (RBH T2*) against a novel work-in-progress (WIP) sequence w...
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 کاملEvaluation of the relationship between hepatic and cardiac iron overload with MRI T2* and carotid intima media thickness with Doppler ultrasound in beta thalassemia major patients
Background: Iron overload is caused early progression of atherosclerosis in beta thalassemia patients due to regular repeated blood transfusion. MRI T2* is a gold standard non-invasive method for detecting hepatic and cardiac iron overload. The aim of this study was the comparison of carotid intima media thickness (CIMT) in the patients and healthy control groups with Doppler ultrasound for ear...
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...
