Is there a benefit from rotating K-SPACE sampling (BLADE) vs. conventional Cartesian K-SPACE sampling (TSE) for routine shoulder MRI?

چکیده
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 (BLADE) was developed, which is supposed to reduce motion artifacts and improve image quality as evaluated for brain and abdominal imaging [1-5]. Given possible benefits for musculoskeletal imaging, this initial study was conducted for comparison of BLADE to a conventional fat-saturated TSE sequence (cTSE) for image quality, anatomical detail depiction and confidence in the detection of shoulder pathologies.

Should less motion sensitive T2-weighted BLADE TSE replace Cartesian TSE for female pelvic MRI?
OBJECTIVES To prospectively compare the diagnostic performance of a non-Cartesian k-space sampling T2-weighted TSE BLADE sequence with a conventional T2-weighted TSE sequence in female pelvic organs. METHODS Forty-seven patients with sonographically indeterminate adnexal masses or uterine lesions underwent sagittal BLADE and conventional TSE at 1.5 T after glucagon administration. Two radiolo...
متن کاملWater Fat Separation with Undersampled TSE BLADE Based on Three Point Dixon
Introduction In the three-point Dixon water fat separation method, one in-phase echo and two out-of-phase echoes are sampled in Cartesian k-space trajectory conventionally [1][2]. The Cartesian sampling is sensitive to motions, such as from pulsation and flow, which cause artifacts degrading the image quality. To address this problem, a non Cartesian sampling method, TSE BLADE three-point Dixon...
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...
متن کاملGradient-Echo Pulse Sequences
The basic idea of parallel imaging is to reduce the number of acquisition steps (i.e. phase-encoding steps) by decreasing the sampling density in kspace. Artefacts, in particular aliasing artefacts, that would result from the reduced sampling density are compensated by employing image data from several independent coil elements with different spatial sensitivity profi les for reconstruction. Th...
متن کاملReconstruction of free-breathing myocardial perfusion MRI using simultanous modeling of perfusion and motion (SMPM) and arbitrary k-space sampling
INTRODUCTION: Respiratory motion of the heart represents a major practical problem in myocardial perfusion MRI. Firstly, the tracer kinetic models used for quantifying perfusion require that the myocardium remains stationary throughout the image time series, thus mandating a prior registration of the images. Secondly, modern k-space undersampling techniques, such as k-t BLAST [1] and UNFOLD [2]...
