549. Validation of a Single Breath Hold Three-dimensional Projection Reconstruction Steady-state Free Precession Magnetic Resonance Imaging Method for Cardiac Function Evaluation
3T is feasible, and is advantageous due to the increased SNR and increased blood-myocardium contrast. Introduction: Three dimensional MR coronary imaging requires scan times longer than possible breath-hold durations. Respiratory motion compensation can be used to increase scan efficiency, reduce exam duration, and improve image quality. Previous studies of respiratory motion of the heart using...
متن کاملVirtual electrophysiological study in a 3-dimensional cardiac magnetic resonance imaging model of porcine myocardial infarction.
OBJECTIVES This study sought to test the hypothesis that "virtual" electrophysiological studies (EPS) on an anatomic platform generated by 3-dimensional magnetic resonance imaging reconstruction of the left ventricle can reproduce the reentrant circuits of induced ventricular tachycardia (VT) in a porcine model of myocardial infarction. BACKGROUND Delayed-enhancement magnetic resonance imagin...
متن کاملFeasibility of automated 3-dimensional magnetic resonance imaging pancreas segmentation
PURPOSE With the advent of MR guided radiotherapy, internal organ motion can be imaged simultaneously during treatment. In this study, we evaluate the feasibility of pancreas MRI segmentation using state-of-the-art segmentation methods. METHODS AND MATERIAL T2 weighted HASTE and T1 weighted VIBE images were acquired on 3 patients and 2 healthy volunteers for a total of 12 imaging volumes. A n...
متن کاملEditorial Commentary: Single-Image Slice Magnetic Resonance Imaging Assessments Do Not Predict 3-Dimensional Muscle Volume.
No single-image magnetic resonance imaging (MRI) assessment-Goutallier classification, Fuchs classification, or cross-sectional area-is predictive of whole-muscle volume or fatty atrophy of the supraspinatus or infraspinatus. Rather, 3-dimensional MRI measurement of whole-muscle volume and fat-free muscle volume is required and is associated with shoulder strength, which is clinically relevant....
متن کاملEffect of variable breath-hold positions during cardiac magnetic resonance on measures of left ventricular mechanics
Background Measures of left ventricular cardiac mechanics such as strains and torsion are becoming increasingly important for assessing heart function. Cardiac magnetic resonance (CMR) can be used to quantify cardiac mechanics using several methods such as tagged CMR or cine Displacement Encoding with Stimulated Echoes (DENSE). These images are generally acquired during an end-expiratory breath...
