Free-breathing Delayed-enhancement 3D MRI With and Without Phase-sensitive Inversion-Recovery
Introduction Free-breathing 3D delayed-enhancement MRI (DE-MRI) has been developed to improve the spatial resolution of the DE-MRI, to generate multi-planar reconstruction, and to eliminate the laborious breath-holds. However, the gadolinium washout during the 4-11-min (mean, about 7 min) scan of the free-breathing 3D DE-MRI may reduce the image contrast because of gadolinium washout from the m...
متن کامل[Usefulness of phase-sensitive inversion recovery in delayed enhanced cardiac MRI].
BACKGROUND Delayed-enhancement MRI is a technique that has significant clinical usefulness, particularly for myocardial viability determination in ischemic heart disease. Delayed enhanced images have been acquired by using the inversion recovery(IR)method. It is necessary for the IR method to select optimal inversion time(TI). Recently, the phase-sensitive inversion recovery(PSIR)method has bee...
متن کاملValidation of Infarct Measurements by Inversion Recovery Delayed-Enhancement MRI during the Hyper-Acute Phase of Myocardial Infarction in Rats
INTRODUCTION — Infarct size is an important measurement for assessing disease progression and treatment efficacy in myocardial infarction (MI), where ex vivo staining with tetrazolium salts such as triphenyltetrazolium chloride (TTC) is regarded as the gold standard. Recently, delayedenhancement (DE)-MRI with gadolinium (Gd)-DTPA has been established as an accurate method for assessing in vivo ...
متن کاملImproved fat water separation with water selective inversion pulse for inversion recovery-based cardiac MRI sequence
Background Chemical shift based water-fat separation methods can be used to reconstruct simultaneous fat and water images, thereby improving the sensitivity of fat detection using a positive fat contrast. The presence of fatty infiltration is a hallmark pathological feature of arrhythmogenic right ventricular cardiomyopathy (ARVC). Furthermore, the presence of fatty infiltration in chronic myoc...
متن کاملOverview of Delayed Myocardial Enhancement in Cardiac MRI
Background: Although MRI has long been used for cardiac imaging, significant improvements in MRI scanners for cardiac specific pulse sequences have only been commercially available since the late 1990’s. Cardiac MRI is a complex and difficult examination that needs not only state-of-the-art MRI scanners, but also staff that is experienced with performing cardiac MRI studies. The main advantages...
