Quantification of myocardial area at risk with T2-weighted CMR: comparison with contrast-enhanced CMR and coronary angiography.
OBJECTIVES We sought to quantify the myocardium at risk in reperfused acute myocardial infarction (AMI) in man with T2-weighted (T2W) cardiac magnetic resonance (CMR). BACKGROUND The myocardial area at risk (AAR) is defined as the myocardial tissue within the perfusion bed distally to the culprit lesion of the infarct-related coronary artery. T2W CMR is appealing to retrospectively determine ...
متن کاملDiagnostic performance of T2-weighted CMR for evaluation of acute myocardial injury
Background Edema-sensitive T2-weighted cardiac magnetic resonance (CMR) based on fast spin-echo (FSE) imaging is a useful modality to detect acute myocardial injury. Conventional T2-weighted CMR uses three inversion-recovery (IR) pulses, the first two to null the blood signal, and the last one (STIR) to null fat signal, but suffers from reduced myocardial signal and signal dropout. We compared ...
متن کاملAssessment and improvement of image homogeneity in black-blood T2-weighted turbo spin-echo CMR
Background Double inversion recovery (DIR) and triple inversion recovery (TIR) prepared Turbo-Spin-Echo (TSE) are the most commonly used sequences for black-blood T2weighted (T2W) cardiac magnetic resonance. For both, cardiac motion often leads to signal loss and image inhomogeneity, which can affect diagnosis. Signal loss artifacts are thought to be due to misalignment of the black-blood prepa...
متن کاملImaging myocardial carcinoid with T2-STIR CMR
We used T2-STIR (Short Tau Inversion Recovery) cardiovascular magnetic resonance to demonstrate carcinoid tumor metastases to the heart and liver in a 64-year-old woman with a biopsy-proven ileal carcinoid tumor who was referred because of an abnormal echocardiogram.
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...
