T2 mapping vs T2 weighted imaging in the detection of myocardial oedema
Background The “gold standard” CMR sequence for assessing the myocardial oedema or area at risk following an acute coronary syndrome is controversial. T2 Short Tau Inversion Recovery (T2-STIR) is in widespread clinical use but can lack robustness. Steady state free precession oedema imaging (SSFP/ ACUT2E) has emerging data to support it as a more reproducible method for area at risk (AAR) asses...
متن کاملT2-mapping and T2*-mapping for detection of intramyocardial haemorrhage: a head-to-head comparison with T2-weighted imaging
Methods Twenty patients underwent CMR at 3T (Achieva TX system, Philips Healthcare, Best, The Netherlands) within 3 days following reperfused ST-elevation MI. Black blood, cine, T2w, T2-mapping, T2*-mapping and LGE imaging (0.1mmol/kg gadolinium DTPA) were performed in identical short axis locations using the ‘3 of 5’ approach. Data were evaluated offline using commercial software (cvi42 v4.1.5...
متن کاملA comparision of oedema detection with diffusion-weighted imaging and T2-STIR imaging in patients with acute myocardial infarction
Background The diffusion weighted imaging (DWI) is a well known technique in neuroradiology, due to its ability to detect ischemic regions in brain tissue. A recent, rapid development of the magnetic resonance technology and echo planar imaging enabled the application of diffusion imaging in cardiac examinations. The aim of this study was to compare the diffusion weighted imaging with widely us...
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 کاملComparison of T1-mapping and T2-weighted imaging for diagnostic oedema assessment in ST-segment elevation myocardial infarction
Background Myocardial oedema (area-at-risk, AAR) is typically imaged using a pre-contrast T2-weighted short tau inversion recovery (T2w-STIR) sequence on cardiovascular magnetic resonance (CMR) imaging. However, this sequence is prone to motion and rhythm artefact, signal dropout, blood-pool artefact, surface coil signal inhomogeneity and potentially prohibitive long breath-hold duration. This ...
