Echo Planar Imaging Sequence. Echo planar imaging (EPI) is the fastest imaging sequence currently available and has the potential to revolutionize many aspects of MR technology.

It is a rapid MRI technique that is capable of producing tomographic images at video rates. It is a single-shot method and imaging times are in the order of ms for. This book describes applications and techniques of the MRI method of echo-planar imaging. I contains detailed and precise accounts of image production, artifacts, and optimization methods.

Applications are imaging of brain function, stroke and cerebral blood flow as well as cardiac and abdominal clinical uses. Echo planar imaging is performed using a pulse sequence in which multiple echoes of different phase steps are acquired using rephasing gradients instead of repeated degree radio frequency pulses following the 90°/° in a spin echo sequence.

This is accomplished by rapidly reversing the readout or frequency- encoding gradient. This switching or reversal may also be done in a sinusoidal. The physics of magnetic resonance imaging (MRI) concerns fundamental physical considerations of MRI techniques and technological aspects of MRI devices.

MRI is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke.

Abstract: Purpose: To determine whether readout-segmented echo-planar imaging (rs-EPI) diffusion-weighted imaging (DWI) can improve the image quality in patients with rectal cancer compared with single-shot echo-planar imaging (ss-EPI) DWI using T magnetic resonance (MR) imaging.

As originally defined, echo planar imaging referred to a sequence in which data from all of k-space for Echo-planar imaging book entire 2D plane was collected following a single RF-excitation pulse.

More recently the term has been expanded to include any rapid gradient-echo or spin-echo sequence in which k-space is traversed in one or a small number of excitations.

In the modern lexicon these are termed single shot. Echo-planar imaging, on the other hand, has been an unqualified success. It is the enabling technology for most fMRI, for tractography, for MRI thermometry and many other applications.

The gradient technologies embedded into the scanner to make EPI possible provide enormous benefits in other sequences as well, such as MP-RAGE and GRACE, that Cited by: 7. Ghosting artifacts are a significant problem for echo-planar images.

These artifacts usually result from amplitude or phase modulation of the k-space data in the phase-encoding direction (1,2).In sequences such as echo-planar imaging (EPI) and gradient and spin-echo (GRASE) imaging, in which lines of k-space are acquired in two directions, incidental phase offsets from receiver electronics and Cited by:   In Chapter 18 of Intermediate Physics for Medicine and Biology, Russ Hobbie and I discuss a type of magnetic resonance imaging called echo-planar imaging.

In EPI the echoes are not created using π pulses. Instead, they are created by dephasing the spins at different positions along the x axis using a G x gradient, and then reversing that gradient to rephase the spins, as shown in Fig. Author: Intermediate Physics For Medicine And Biology. This book describes applications and techniques of the MRI method of echo-planar imaging.

I contains detailed and precise accounts of image production, artifacts, and optimization methods. Applications are imaging of brain function, stroke and cerebral blood flow as well as cardiac and abdominal clinical uses.

Except for single-shot echo planar imaging (EPI) or other real-time imaging approaches, CMR requires gating to the electrocardiogram (ECG) or peripheral pulse.

Problems with gating can result in ghosting and other noise that degrades the quality of the images. In general, focused efforts to obtain the best ECG possible before beginning scanning will minimize cardiac motion artifacts and save time.

[Franz Schmitt; Michael K Stehling; Robert Turner] -- This book describes applications and techniques of the MRI method of echo-planar imaging. I contains detailed and precise accounts of image production, artifacts, and optimization methods.

Echo-planar imaging is a very fast magnetic resonance (MR) imaging technique capable of acquiring an entire MR image in only a fraction of a second. In single-shot echo-planar imaging, all the spatial-encoding data of an image can be obtained after a single radio-frequency excita-tion.

Multishot echo-planar imaging results in high-quality images. Speed continues to be one of the most powerful features that echo-planar imaging (EPI) can offer relative to other magnetic resonance imaging (MRI) techniques.

For most conventional MRI sequences, data acquisition is still slower than many dynamic physiological processes, often yielding images plagued with motion artifacts that can obscure Author: P. Wielopolski, O. Simonetti, J. Duerk. So echo-planar imaging can be reflected as a multi echo variant of the GRE sequence same as the fast SE is a multi-echo variant of the SE sequence.
