Is there a benefit from rotating K-SPACE sampling (BLADE) vs. conventional Cartesian K-SPACE sampling (TSE) for routine shoulder MRI?
Purpose: In shoulder-MRI the radiologist is often confronted with involuntary patient movement which might produce artifacts and consecutively non-diagnostic images using conventional TSE sequences with common Cartesian block-wise linear readout of k-space. Recently a multishot T2weighted sequence based on rotating rectangular read-out of k-space data after successive radiofrequency excitations...

متن کاملOptimal k-space sampling for dynamic contrast-enhanced MRI with an application to MR renography.
For time-resolved acquisitions with k-space undersampling, a simulation method was developed for selecting imaging parameters based on minimization of errors in signal intensity versus time and physiologic parameters derived from tracer kinetic analysis. Optimization was performed for time-resolved angiography with stochastic trajectories (TWIST) algorithm applied to contrast-enhanced MR renogr...
متن کاملAccelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
