What does FSE mean in MRI?

What does FSE mean in MRI?

Fast spin echo (FSE) imaging, also known as Turbo spin echo (TSE) imaging, are commercial implementations of the RARE (Rapid Acquisition with Relaxation Enhancement) technique originally described by Hennig et al in 1986.

What is haste MRI sequence?

The half-Fourier single-shot turbo spin-echo (HASTE) sequence [1] is an ultrafast magnetic resonance (MR) imaging technique that acquires slightly more than half of two-dimensional imaging k-space after a single excitation pulse by means of an echo train separated by refocusing pulses.

What is single shot fast spin echo?

[Single shot fast spin echo (SSFSE)]

How does the fast spin echo sequence reduce scan times?

In fast spin echo sequences, the interval of time after the first echo, is used to receive the echo train, to fill the other k-space lines in the same slice . Because of the reduced number of repetitions (TR) required, the k-space is filled faster and slice acquisition time is reduced.

What is FSE used for?

Fast or turbo spin echo (FSE/TSE) is an adaptation of conventional spin-echo (SE) acquisition technique designed to reduce imaging time. It has largely supplanted the original spin-echo technique due to vastly improved imaging speed.

What is the fastest MRI sequence?

Echo planar imaging (EPI) is perhaps the fastest sequence available and is the most common sequence used for diffusion-weighted imaging. It essentially forms rapidly alternating gradient echoes within a spin echo sequence.

What is a vibe sequence MRI?

Volumetric Interpolated Breath-hold Examination (VIBE) sequence is a modified form of FLASH sequence, which permits dynamic and high-resolution imaging under 30 seconds breath-hold.

What is the difference between spin echo and fast spin echo?

Fast spin echo offers increased resolution in a comparable time to conventional spin echo by increased number of excitations and finer matrix size, thus improving the signal-to-noise ratio and spatial resolution, respectively.

What are pulse sequences in MRI?

An MRI pulse sequence is a programmed set of changing magnetic gradients. Each sequence will have a number of parameters, and multiple sequences grouped together into an MRI protocol.
