We aimed to compare the deep learning-based single-shot turbo spin-echo (DL-SSTSE) images of female pelvis with turbo spin-echo (TSE) and conventional SSTSE images in terms of image quality. One hundred five and 21 subjects were used as training and test sets, respectively. We performed 6-fold cross validation. Turbo spin echo sequence We can take the multi-echo sequence further. We can repeat the 180° RF pulses many times, creating many echoes, within one cycle. If we apply a different G PE each time we can fill up different lines of k-space. The number of echoes we create is called the " echo train length (ETL) ".

This segmentation has several advantages: shorter effective echo time, lower bandwidth, less T2 decay, and fewer artifacts. Keywords Spin Echo Magnetic Resonance Cholangiography Radio Frequency Pulse Magnetom Vision Plane Resolution These keywords were added by machine and not by the authors. HASTE is an echo-planar fast spin echo sequence trademarked by Siemens. The expanded acronym fairly completely describes what it entails: H alf-Fourier A cquisition S ingle-shot T urbo spin E cho imaging. Other vendors have similar sequences under slightly different names: GE (Single-shot fast spin echo, SS-FSE ), Philips (Single-shot turbo. Three-dimensional (3D) turbo-spin echo (TSE) sequences have outgrown the stage of mere sequence optimization and by now are clinically applicable. Image blurring and acquisition times have been reduced, and contrast for T1-, T2-, and moderately T2-weighted (or intermediate-weighted) fat-suppressed variants has been optimized.

Accuracy of Postcontrast 3D Turbo Spin-Echo MR Sequence for.

Demonstration of most anatomical structures and disorders was equivalent with TSE and SE sequences. Advantages of TSE were reduced flow artefacts on T2-weighted images, better lesion contrast on PD-weighted TSE images (especially in the dual-echo sequence) and acquisition time reduction to about 5 min (single-echo TSE) and 3:35 min (dual-echo TSE). The pulse sequence timing can be adjusted to give T1-weighted, proton density, and T2-weightedimages. Dual echo and multiecho sequences can be used to obtain both proton density and T2-weighted images simultaneously. The two variables of interest in spin echo sequences are the repetition time (TR) and the echo time (TE).

TSE/FSE - Questions and Answers in MRI.

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. Purpose: To compare isotropic 3D T2-weighted (T2W) turbo spin-echo sequence (TSE-SPACE) with standard two-dimensional (2D) T2W TSE imaging for evaluating lumbar spine pathology at 3.0 T MRI. Material and methods: Forty-two patients who had spine surgery for disk herniation and had 3.0 T spine MRI were included in this study. In addition to. Three-dimensional (3D) turbo-spin echo (TSE) sequences have outgrown the stage of mere sequence optimization and by now are clinically applicable. Image blurring and acquisition times have been reduced, and contrast for T1-, T2-, and moderately T2-weighted (or intermediate-weighted) fat-suppressed variants has been optimized. Data on sound-to-noise ratio efficiency and contrast are available.

Purpose To compare a three-dimensional (3D) T2-weighted turbo spin-echo (TSE) magnetic resonance (MR) sequence (VISTA; Philips Medical Systems, Best, the Netherlands) with a two-dimensional (2D) T2-weighted TSE sequence in terms of image quality, signal intensity (SI) difference ratios, conspicuity, and staging of uterine tumors. Materials and Methods This retrospective study was approved by.

Uterine Tumors: Comparison of 3D versus 2D T2-weighted Turbo Spin-Echo.

First, the significant time savings by scanning multiple lines of k -space may be used to lengthen TR, allowing more time for recovery of longitudinal magnetization and hence improved signal-to-noise. A higher number of phase-encoding steps may be used, allowing improvement in spatial resolution..

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)..

MRI Sequences - Fast Spin Echo Sequences - MR-TIP.

3D fast spin-echo sequences are relatively recent MRI pulse sequences that are able to rapidly image relatively large volumes of tissue with high resolution whilst retaining many of the advantages of fast spin-echo sequences.. They are able to create the same weightings as traditional 2D sequences (i.e., T1, T2, proton density, and FLAIR) with submillimeter isotropic resolution 1,2. 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. Since.

Fast spin-echo - TSE/FSE - Questions and Answers in MRI.

Ultrashort Turbo Spin Echo (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. Three-dimensional (3D) turbo-spin echo (TSE) sequences have outgrown the stage of mere sequence optimization and by now are clinically applicable. Image blurring and acquisition times have been reduced, and contrast for T1-, T2-, and moderately T2-weighted (or intermediate-weighted) fat-suppressed variants has been optimized. The turbo spin echo (TSE) technique is an alternate approach for DWI. Because it uses a 180° RF refocusing pulse for each measured echo, susceptibility artifacts and image distortion are lower than on EPI-DWI scans. Previous reports suggested that decrease in the SNR and a long acquisition time are disadvantages of TSE-DWI.

(a) Double inversion recovery turbo spin echo (DIR-TSE). (b) Fluid and white matter suppression magnetization-prepared with two rapid gradient echoes (FLAWS-MP2RAGE). The vertical scales are not consistent in arbitrary unit. Gradient-recalled echo (GRE) #1 and #2 are the first and the second GRE in MP2RAGE sequence. BACKGROUND AND PURPOSE: Therapeutic strategies for patients with MS partly rely on contrast-enhanced MR imaging. Our aim was to assess the diagnostic performance of 3D turbo spin-echo MR imaging with variable refocusing flip angles at 3T for the detection of enhanced inflammatory lesions in patients with multiple sclerosis. MATERIALS AND METHODS: Fifty-six patients with MS were prospectively. 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.
