High-resolution echo-planar spectroscopic imaging of the human calf. [PDF]
PLoS ONE, 2014 BACKGROUND: This study exploits the speed benefits of echo-planar spectroscopic imaging (EPSI) to acquire lipid spectra of skeletal muscle. The main purpose was to develop a high-resolution EPSI technique for clinical MR scanner, to visualise the bulk ...

Evaluation of 2D Imaging Schemes for Pulsed Arterial Spin Labeling of the Human Kidney Cortex
Diagnostics, 2018 A number of imaging readout schemes are proposed for renal arterial spin labeling (ASL) to quantify kidney cortex perfusion, including gradient echo-based methods of balanced fast field echo (bFFE) and gradient-echo echo-planar imaging (GE-EPI), or spin ...

3D Echo Planar Time-resolved Imaging (3D-EPTI) for ultrafast multi-parametric quantitative MRI
NeuroImage, 2022 Multi-parametric quantitative MRI has shown great potential to improve the sensitivity and specificity of clinical diagnosis and to enhance our understanding of complex brain processes, but suffers from long scan time especially at high spatial ...

Fast 3 T nigral hyperintensity magnetic resonance imaging in Parkinson’s disease
Scientific Reports, 2021 The absence of nigral hyperintensity is a promising MR marker for Parkinson’s disease (PD), but its small size imposes limitations on its routine use. Our aim was to compare Multi Echo Data Image Combination (MEDIC), segmented echo-planar imaging (EPISEG)

Multiband echo‐shifted echo planar imaging [PDF]
Magnetic Resonance in Medicine, 2016 PurposeTo propose the technique multiband echo‐shifted (MESH) echo planar imaging (EPI), which combines the principles of echo‐shifted acquisition for two‐dimensional multislice EPI, with both in‐plane and multiband acceleration by means of partial parallel imaging techniques.MethodsMESH EPI is suitable for functional MRI (fMRI) in situations where ...

Echo planar time‐resolved imaging (EPTI) [PDF]
Magnetic Resonance in Medicine, 2019 PurposeTo develop an efficient distortion‐ and blurring‐free multi‐shot EPI technique for time‐resolved multiple‐contrast and/or quantitative imaging.MethodsEPI is a commonly used sequence but suffers from geometric distortions and blurring. Here, we introduce a new multi‐shot EPI technique termed echo planar time‐resolved imaging (EPTI), which has the

RadioGraphics, 1994 Echo-planar imaging is a fast magnetic resonance (MR) imaging technique that allows acquisition of single images in as little as 20 msec and performance of multiple-image studies in as little as 20 seconds. Echo-planar imaging achieves its speed by obtaining all spatial-encoding information after a single radio-frequency (RF) excitation.
