Temporal Interpolation of Abdominal MRIs Acquired During Free-Breathing …

WebPurpose: To develop a free-breathing, non-electrocardiogram technique for simultaneous myocardial T 1, T 2, T 2 *, and fat-fraction (FF) mapping in a single scan. Methods: The MR Multitasking framework is adapted to quantify T 1, T 2, T 2 *, and FF simultaneously. A variable TR scheme is developed to preserve temporal resolution and imaging efficiency. WebBackground: Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been shown to be a promising technique for assessing lung lesions. However, DCE-MRI often suffers from motion artifacts and insufficient imaging speed. Therefore, highly accelerated free-breathing DCE-MRI is of clinical interest for lung exams.
