What is a Trufi sequence?

True FISP is the Siemens trade name for a steady-state coherent sequence in which balanced gradients are used along all three axes. “Balanced” means that the net gradient-induced dephasing over a TR interval is zero.

What is Btfe sequence?

A balanced turbo field echo (BTFE) MRI sequence, which achieves rapid and high-resolution imaging of the spinal anatomical structures, reveals a gap in the anterior dura mater at the T5-T6 level. (a) sagittal-, and (b) axial-oriented images.

What is Vibe sequence?

Volumetric interpolated breath-hold examination (VIBE) sequence is a radio-frequency–spoiled 3D GRE sequence. This sequence produces T1 weighted 3D images using interpolation and/or partial Fourier techniques.

What does FISP stand for in MRI?

true FISP: fast imaging with steady-state free precession.

What is T2 haste?

HASTE (Half fourier Single-shot Turbo spin-Echo) is a single-section T2-weighted sequence that acquires images in less than 1 second. Images are breathing independent and possess a variety of other features useful for imaging the abdomen.

What is fiesta in GE MRI?

FIESTA (Fast Imaging Employing Steady-state Acquisition) is the GE name for a balanced steady-state gradient echo sequence that Siemens calls TrueFISP and Philips calls balanced-FFE. As described in a prior Q&A, these sequences may be affected by phase shift errors across the image that produce banding artifacts.

Is haste T1 or T2?

T2-weighted
Abstract. The half-Fourier acquisition single-shot turbo-spin-echo (HASTE) sequence allows for heavily T2-weighted images, and the inversion recovery (IR)-HASTE sequence represents the T1 value of the tissue in a very short time.

What is Fiesta CISS MRI?

FIESTA-C/CISS is currently the sequence of choice for CSF-cisternography for visualizing cranial nerves at the skull base. When used in the 3D mode, it provides high signal from CSF based on T2/T1 contrast and high spatial resolution.

What is Fiesta MRI used for?

Background/Aims. In Gamma Knife radiosurgery, T1 MRI is most commonly used and is generally sufficient for targeting the trigeminal nerve. For patients whose trigeminal nerves are unclear on T1 MRI, FIESTA MRI supplements anatomical structure visualization and may improve trigeminal nerve delineation.

What is T2 Frfse?

The FRFSE sequence is a variation of the conventional T2-weighted fast spin echo sequence in which an additional 180 degree refocusing pulse and negative 90 degree RF pulse are applied to accelerate the recovery of longitudinal magnetization.

What type of MRI is used for trigeminal neuralgia?

Magnetic resonance image (MRI) with high resolution on the pons demonstrating the trigeminal nerve root. In this case, the patient with trigeminal neuralgia has undergone gamma-knife therapy, and the left-sided treated nerve (arrow) is enhanced by gadolinium.
