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.

The T2 True Fast Imaging with Steady State Precession (TrueFISP) or Fast Imaging Employing Steady-state Acquisition (FIESTA) MRI sequence is an advanced imaging technique that capitalizes on a fully balanced gradient waveform.

Nov 30, 2022 · This article contains a list of commonly and less commonly used MRI pulse sequence abbreviations and their meaning. If available, an explanation is included in a separate article. T2*: T2 star. PRESS: point resolved spectroscopy.

CISS (Constructive Interference in Steady State) MRI is an advanced imaging technique derived from the TrueFISP sequence. It utilizes specialized radiofrequency pulses, gradient echo sequences, and a T2-weighted 3D gradient echo technique to …

The FIESTA sequence uses the T2 steady state contrast mechanism to provide high SNR images with strong signal from fluid tissues while suppressing background tissue for contrast and anatomic detail of small structures.

For most solid tissues, the T2/T1 ratio is small. The exceptions are fat (0.30) and fluids (0.70). Thus True FISP sequences tend to highlight fluids such as CSF and blood, making them ideal for cardiovascular MRI, MR cisternography/myelography, MR urography, and MR enterography.

Nov 23, 2012 · Despite the poor T2 tissue contrast of FIESTA relative to conventional T2-weighted imaging (e.g., FSE-based T2-weighted images), FIESTA allows visualization of solid masses in the liver that have higher SNR than the liver and …

The purpose of this study was to compare the diagnostic value of fast spin-echo T2 weighted (FSE-T2W), fat-suppressed T2W (FS-T2W), and three-dimensional (3D) fast imaging employing steady-state acquisition (FIESTA-C) MR sequences for early detection of bone marrow changes as well as TMJ soft tissue alterations.

Sep 4, 2022 · Generally these sequences exploit what is referred to as T2* (T2 star) which is highly sensitive to small perturbations in the local magnetic field. The most sensitive of these sequences is known as susceptibility weighted imaging (SWI) and is also able to distinguish calcium from blood.

Sep 1, 2016 · We believe that the high positive findings in our study were due to the use of 3D-FIESTA beside pre- and post-contrast axial and coronal sequences. The FIESTA sequence is a high-resolution T2-weighted MRI sequence that provides outstanding image contrast and high signal-to noise-ratio.
