Fast spin echo FSE Siemens, Philips. Turbo spin echo TSE With each TR in a CSE, we have a single phase-encoding step. Each of the echoes following each 180#176; pulse is obtained after a single application of the phase. Rationale and Objectives: We aimed to compare the distortion ratio DR, signal-to-noise ratio SNR, and contrast-to-noise ratio CNR between turbo spin-echo TSE-diffusion-weighted imaging DWI and echo-planar imaging EPI-DWI of the orofacial region and prove the usefulness of TSE-DWI for the differential diagnosis of orofacial lesions.

The one thing that sets a spin echo apart from the rest is the 180 degree refocusing pulse. This pulse is used to refocus decaying hydrogen protons to provide accurate T2 weighting. The spin echo family consists of the convention spin echo, the fast spin echo, the inverse recovery sequence, the single shot sequence, DRIVE, and the hydrid sequence. Thus, the 180-degree pulse must happen at TE/2. Repetition. As we have discussed, the spin echo sequence has 3 main phases: 1 90-degree pulse followed by free induction decay; 2 180-degree pulse followed by rephasing; and 3 the echo that occurs at TE, when the scanner acquires the signal referred to as readout. Today, T2-FLAIR has largely supplanted spin-density-weighted SE images for most applications, so multi-echo SE is only occasionally used. Fast Turbo Spin Echo FSE Multi-echo SE should be distinguished from FSE where multiple 180-pulses and echoes also follow each 90-pulse. The simplified FSE pulse-echo timing diagram appears below.
Comparison between turbo spin-echo and echo planar diffusion.
Purpose: 2D turbo-spin-echo TSE is widely used in the clinic for neuroimaging. However, the long refocusing radiofrequency pulse train leads to high specific absorption rate SAR and alters the contrast compared to conventional spin-echo. Purpose: To qualitatively and quantitatively compare the image quality and diagnostic performance of turbo gradient and spin echo PROPELLER diffusion-weighted imaging TGSE-PROPELLER-DWI vs. readout-segmented echo-planar imaging rs-EPI in the evaluation of orbital tumors.Materials and Methods: A total of 43 patients with suspected orbital tumors were enrolled to perform the two DWIs with.
RARE/turbo spin echo imaging with simultaneous multislice Wave-CAIPI.
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-weightedimages. TSE Turbo Spin Echo or Fast Spin Echo pulse sequences, with efficient acquisition of T1, T2 and proton density weighted images, have become useful in the evaluation of cervical carotid artery disease 7-9. High resolution 3D TSE techniques would be valuable in carotid MRI, but motion artifacts that arise due to the relatively long data.

The benefit of this technique is that the scan duration with, e.g. a turbo spin echo turbo factor / echo train length of 9, is one ninth of the time. In T1 weighted and proton density weighted sequences, there is a limit to how large the ETL can be e.g. a usual ETL for T1 weighted images is between 3 and 7. The use of large echo train lengths. Fast spin echo 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. Our 2D multislice turbo spin-echo sequence combined with a driven equilibrium pulse provides a bright signal of joint fluid with otherwise unchanged signal intensities as compared with a normal T1-weighted turbo spin-echo sequence at high spatial resolution and short scan times. Thus, it might represent a useful adjunct for routine joint.

An alternative turbo spin echo sequence, DW-SPLICE, is implemented and demonstrated in patients. Methods. The DW-SPLICE sequence was implemented on a 3.0 T system and evaluated in 10 patients. The patients were scanned in treatment position, using a customized head support and immobilization mask. Image distortions were quantified at the gross.

Turbo-spin-echo TSE imaging is a fast technique, which provides true spin-echo contrast in a definitely shorter scan time than conventional spin-echo SE. Clinical studies at 1.5 T show that TSE is a valuable alternative to SE and will ultimately replace time-consuming T2-weighted SE imaging for examinations of the brain and brainstem.
A 2D spiral turbo-spin-echo technique Mayo Clinic.
The turbo spin echo TSE method is an alternate approach for performing DWI. Because TSE-DWI uses a 180#176; RF refocusing pulse for each measured echo, susceptibility artifacts are smaller and image distortion is less marked than with EPI-DWI. Objectives. Multi spin echo MSE sequences are often used for obtaining T2-relaxometry data as they provide defined echo times TEs. Due to their time-consuming acquisition, they are frequently replaced by turbo spin echo TSE sequences that in turn bear the risk of systematic errors when analyzing small structures or lesions. With this study, we aim to test whether T2-relaxometry data.
