Spin Echo - MRI SHARK.
Fast spin echo (FSE) sequences have replaced conventional T2 weighted spin echo sequences for most clinical applications. Fast spin echo allows reduced acquisition times and enables T2 weighted breath hold imaging, e.g. for applications in the upper abdomen. In case of the acquisition of 2 echoes this type of a sequence is named double fast.
Fast spin-echo - TSE/FSE - Questions and Answers in MRI.
There are many sequences used in MRI, each one aimed at increasing the tissue contrast of interest. The basic sequences are: Spin echo; Gradient echo; We will first go through the spin echo sequence. A spin echo sequence aims to remove the effects of the static field T2 but leave the tissue characteristic T2 effect. Contrast-Enhanced High-Resolution Intracranial Vessel Wall MRI with Compressed Sensing: Comparison with Conventional T1 Volumetric Isotropic Turbo Spin Echo Acquisition Sequence Chae Jung Park , MD, PhD, 1 Jihoon Cha , MD, PhD, 1 Sung Soo Ahn , MD, PhD, 1 Hyun Seok Choi , MD, PhD, 1 Young Dae Kim , MD, PhD, 2 Hyo Suk Nam , MD, PhD, 2 Ji Hoe Heo. Spin-echo sequences are characterized by 180° RF rephasing pulses that refocus the magnetic moments of spins to produce an echo, T1, T2, and PD weighting are all achievable using conventional spin-echo, Conventional spin-echo is traditionally used to acquire one or two echoes to achieve T1, T2, or proton density weighting, Although they are old sequences, they are still considered the gold.
Abbreviated Turbo Spin Echo T2- and FLAIR-weighted Sequences to.
The acquisition of spin-echo images can be understood as follows: The patient is placed into the MRI machine. Once inside the machine all hydrogen ions in the different body tissues will align parallel with the magnetic field of the machine. Then, a coil emits RF pulses that cause the axis of these ions to change 90º.

What is dual echo sequence in MRI? Dual echo and multiecho sequences can be used to obtain both proton density and T2-weighted images simultaneously. Objective: To compare the diagnostic performance of modified Dixon (mDixon) turbo spin echo (TSE) T2 weighted MRI and conventional T1 weighted MRI in vertebral metastasis detection. Methods: Between September 2014 and October 2016, 33 patients with 68 metastases who had undergone whole-spine MRI were enrolled. The following sagittal image sets were evaluated: T1WI, and mDixon TSE T2 weighted.

Ultrafast sequence providing high resolution imaging or extremely short acquisition times. Hybrid Turbo Spin Echo/Gradient Echo used primarily for T2-weighted imaging. Shorter measurement time; Decreased RF power deposition; Improved visualization of hemorrhage due to magnetic susceptibility differences; High resolution imaging of brain and spine.
Diffusion‐weighted MRI of the lung at 3T evaluated using echo‐planar.
Researchers found isotropic 3-D turbo echo-spin sampling to be a reliable MRI sequence that demonstrated high accuracy for morphological knee cartilage imaging at 3 T. Additionally, although. The standard sequence used in the MRI examination of the female pelvis in the sagittal section is the T2 Weighted Turbo Spin Echo (T2W TSE). However, the use of the Turbo Spin Echo (TSE) is sensitive to movement , so that motion artifacts often appear. To reduce artifacts researchers tried. To address these susceptibility-induced image distortions, DW-MRI can also be acquired using Turbo Spin Echo (TSE) type imaging sequences. Here, the EPI acquisition module is replaced by a single-shot TSE module, which improves the geometrical accuracy. TSE diffusion has been explored previously in the head-and-neck region for various applications.

Fast spin echo (FAISE or FSE, ref 65bis), also called turbo spin echo (TSE) is an MRI sequence that results in fast scan times. In this sequence, several 180 refocusing radio-frequency pulses are delivered during each echo time (TR) interval, and the phase-encoding gradient is briefly switched on between echoes.

(UTSE) The ultrashort turbo spin echo ( TSE / FSE) sequence is a technique with extremely short echo spacing, resulting in shorter scan times. This is an advantage in areas where motion is a problem, for example dynamic or abdominal imaging.

Background This work was conducted to assess the diagnostic efficiency of isotropic three-dimensional VISTA-fast spin echo versus standard two-dimensional fast spin echo at 1.5 T MRI, in the assessment of internal knee derangement in symptomatic patients, aiming to obtain similar diagnostic accuracy in a shorter time span, with reduction of partial volume artifacts by thin continuous sections. Purpose: Multi-echo spin-echo sequence is commonly used for T 2 mapping. The estimated values using conventional exponential fit, however, are hampered by stimulated and indirect echoes leading to overestimation of T 2.Here, we present fast analysis of multi-echo spin-echo (FAMESE) as a novel approach to decrease the complexity of the search space, which leads to accelerated measurement of T 2.

As a general rule, images acquired with Fast or Turbo Spin Echo sequences (FSE/TSE) will result in images with fewer susceptibility artifacts than those acquired using gradient echo sequences. However, it is not always possible to replace gradient echo sequences with FSE sequences. Strategic selection of sequence parameters can be very effective. 3D isotropic sequence has the potential to allow more detailed assessment for internal derangement because of its high tissue con-trast and slice resolution.

Liver diffusion-weighted MR imaging with L1-regularized iterative.
Spin-echo pulse sequences are one of the earliest developed and still widely used (in the form of fast spin echo) of all MRI pulse sequences. The pulse sequence timing can be adjusted to give T1-weighted, proton density, and T2. Turbo Gradient Spin Echo. (TGSE / TurboGSE) A sequence with a combination of Gradient and Spin Echo Imaging. Additional gradient echoes are generated before and after each spin echo. The spin echoes are allocated to the center of the raw data matrix to give pure T2 contrast. The gradient echoes primarily determine the image resolution.
