Parallel MR imaging.
Parallel imaging is a robust method for accelerating the acquisition of magnetic resonance imaging (MRI) data, and has made possible many new applications of MR imaging. Parallel imaging works by acquiring a reduced amount of k-space data with an array of receiver coils. These undersampled data can be acquired more quickly, but the undersampling leads to aliased images. One of several parallel ...
متن کاملParallel MR imaging: a user's guide.
Parallel imaging is a recently developed family of techniques that take advantage of the spatial information inherent in phased-array radiofrequency coils to reduce acquisition times in magnetic resonance imaging. In parallel imaging, the number of sampled k-space lines is reduced, often by a factor of two or greater, thereby significantly shortening the acquisition time. Parallel imaging techn...
متن کاملA new phantom using polyethylene glycol as an apparent diffusion coefficient standard for MR imaging.
In recent years, magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) has seen wide clinical use, such as for early detection of cerebrovascular diseases and whole body screening for tumors. The apparent diffusion coefficient (ADC) standard phantom, which mimics the ADC values of several lesions in the body, is indispensable for the development of new pulse sequences for DWI, ...
متن کاملHighly Accelerated Contrast-Enhanced MR Angiography using Ghost Imaging
Introduction: Contrast-enhanced MRA (CE-MRA) is a well-established methodology that accurately depicts vessel morphology in multiple vascular territories. In order to minimize the signal contribution from background tissues, a precontrast data set is typically subtracted from the post-contrast data set. Parallel acceleration techniques such as GRAPPA and SENSE are routinely used to improve spat...
متن کاملMR elastography of liver transplant patients using parallel imaging techniques
Background: Hepatitis C graft-infection after liver transplantation is seen in virtually all hepatitis-C-virus (HCV) positive patients and causes fibrosis. In magnetic resonance elastography (MRE) tissue mechanical properties are derived by analyzing externally introduced tissue vibrations using phase contrast based MRI [1]. MRE has already shown its strong potential in grading hepatic fibrosis...
