Quantification of Nonenhancing Tumor Burden in Gliomas Using Effective T2 Maps Derived from Dual-Echo Turbo Spin-Echo MRI.
PURPOSE Evaluation of nonenhancing tumor (NET) burden is an important yet challenging part of brain tumor response assessment. This study focuses on using dual-echo turbo spin-echo MRI as a means of quickly estimating tissue T2, which can be used to objectively define NET burden. EXPERIMENTAL DESIGN A series of experiments were performed to establish the use of T2 maps for defining NET burden...
متن کاملMyocardial T2 mapping is better than T2W Turbo Spin Echo for the diagnosis of acute myocarditis at 3T CMR
Background Myocardial edema is usually assessed by T2W Turbo Spin Echo (TSE), using either Triple Inversion Recovery (STIR) or Double Inversion Recovery (DIR) with spectral fat saturation. Both TSE sequences have important drawbacks, such as low SNR when using the body coil, dropout of the lateral wall signal and use of semi-quantitative analysis by computing the ratio of myocardial to skeletal...
متن کاملT2-prepared SSFP improves diagnostic confidence in edema imaging in acute myocardial infarction compared to turbo spin echo.
T2-weighted MRI of edema in acute myocardial infarction (MI) provides a means of differentiating acute and chronic MI, and assessing the area at risk of infarction. Conventional T2-weighted imaging of edema uses a turbo spin-echo (TSE) readout with dark-blood preparation. Clinical applications of dark-blood TSE methods can be limited by artifacts such as posterior wall signal loss due to throug...
متن کاملCardiac magnetic resonance T2 relaxometry in acute myocarditis correlations with myocardial function and cardiac biomarkers
Background Myocarditis is a common inflammation of the myocardium with variable symptoms, which is in daily clinical routine quite difficult to diagnose. Cardiac magnetic resonance imaging assumes an increasingly important role in the diagnosis of myocarditis by their exact functional analysis and the possibility of representation of tissue changes. The aim of this clinical trial consists in th...
متن کاملMyocardial edema as detected by pre-contrast T1 and T2 MRI delineates area at risk associated with acute myocardial infarction
Objectives—To determine whether cardiac magnetic resonance (CMR) in vivo T1-mapping can measure myocardial area at risk (AAR) compared with microspheres or T2-mapping CMR. Background—If T2-weighted CMR is abnormal in the AAR due to edema related to myocardial ischemia, then T1-weighted CMR should also be able to detect and accurately quantify AAR. Methods—Dogs (n=9) underwent a 2 hour coronary ...
