Comparison of T2-preparation and magnetization-transfer preparation for black blood delayed enhancement
نویسندگان
چکیده
Background A fundamental component of the CMR exam is contrast enhanced imaging, which is crucial for delineating diseased from normal tissue. Unfortunately, diseased tissue immediately adjacent to blood often is hidden since there is poor contrast between hyperenhanced tissue and bright blood. A new method recently described, Flow-Independent Dark-blood DeLayed Enhancement technique (FIDDLE), allows visualization of tissue enhancement while suppressing blood signal. One critical part of FIDDLE is the prep pulse prior to inversion, which accentuates differences in magnetization between tissue and blood. In this study, we compared a T2-prep and a magnetization transfer (MT) prep for use with FIDDLE.

Black blood late gadolinium enhancement using combined T2 magnetization preparation and inversion recovery
Background Late gadolinium enhancement (LGE) imaging allows assessment of focal scar [1]. An inversion recovery based sequence is commonly used to achieve suppression of healthy myocardium signal. However, the blood pool and subendocardial scar typically have similar signal, making it difficult to distinguish subendocardial scar. Several methods have been proposed to increase the blood-scar con...
متن کاملFree-breathing 3D cardiac function with accelerated magnetization transfer prepared imaging
Background 3D cardiac MRI has long held promise for improved heart coverage, higher resolution, and reduced sensitivity to poor breath-hold reproducibility. However, its use has been limited by reduced blood pool to myocardium contrast for spoiled and balanced steady-state free precession (bSSFP) implementations. T2-preparation techniques [1] are capable of increasing contrast but are unfortuna...
متن کاملHigh-Field MR Venography using Adiabatic T2 Magnetization Preparation
Introduction Highlighting the lumen of veins while attenuating arterial signal in MRI can be of use for several clinical purposes such as guiding the placement of pacemaker leads [1] or the diagnosis of venous thrombi [2]. At a magnetic field strength of 1.5 T, coronary venography has successfully been implemented with magnetization transfer contrast (MTC) [3] prepulses. Unfortunately this appr...
متن کاملB1-insensitive T2 preparation for improved coronary magnetic resonance angiography at 3 T.
At 3 T, the effective wavelength of the RF field is comparable to the dimension of the human body, resulting in B1 standing wave effects and extra variations in phase. This effect is accompanied by an increase in B0 field inhomogeneity compared to 1.5 T. This combination results in nonuniform magnetization preparation by the composite MLEV weighted T2 preparation (T2 Prep) sequence used for cor...
متن کامل"Spin-echo Like T1 Contrast" Volumetric Black-Blood Images Using 3D LOWRAT: Low Refocusing Flip Angle TSE
Introduction: T1 contrast is typically acquired using multi-slice two-dimensional spin-echo (2D SE), inversion recovery fast spin echo (T1 fluid-attenuated inversion recovery : T1FLAIR) or 3D T1-weighted spoiled gradient-echo (3D T1TFE) imaging [1]. However, these conventional methods have problems when used for contrast enhancement studies. 2D-SE requires long scan time for 3-plane diagnosis, ...
