Spin echo v FSE - Questions and Answers in MRI.

Abstract 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. 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.

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

Explain the contrast obtained, the advantages and disadvantages of each sequence Present the sequence acceleration techniques in spin echo Examine the effect of inversion-recovery on contrast and its applications Define the relationship between TR, flip angle and longitudinal magnetization in gradient 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.

To compare an ultrafast T2-weighted (half-Fourier acquisition single-shot turbo spin-echo [HASTE]) pulse sequence with fast spin-echo T2-weighted sequences in MR imaging of brain lesions. 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). Objective To evaluate three-dimensional (3D) turbo spin-echo (TSE) magnetic resonance imaging (MRI) for the assessment of acute muscle injuries in elite athletes in comparison with two-dimensional (2D) MRI. Methods Elite athletes with clinically suspected acute muscle injury of the thigh who underwent both 2D and 3D MRI protocols on the same day were retrospectively included. Two.

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.

The benefit of this pulse sequence is that we are able to achieve T2 and proton density weighting in our image without having to wait a long repetition time. This will shorten our scan time when our minimum repetition time is very short. Disadvantage This extra RF pulse may also cause heating in our image. Hybrid.

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

Fast or turbo spin echo ( FSE / TSE) is an adaptation of conventional spin-echo (SE) acquisition technique designed to reduce imaging time. It has largely supplanted the original spin-echo technique due to vastly improved imaging speed. Basic spin echo sequence In a basic SE sequence, a single echo is measured during each repetition time (TR).

Turbo spin echo (TSE) or fast spin echo pulse sequences, with efficient acquisition of T 1 ‐, T 2 ‐, 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.

[Turbo-spin-echo MR imaging of the brain at 0.5 T].

Fast spin echo images are more T2 weighted, which makes it difficult to obtain true proton density weighted images. For dual echo imaging with density weighting, the TR should be kept between 2000 - 2400 msec with a short ETL (e.g., 4). Other terms for this technique are: Turbo Spin Echo Rapid Imaging Spin Echo, Rapid Spin Echo,. (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.

The advantage is that the images are obtained with a different contrast, which is useful in characterizing certain lesions (for example, highlighting contrast at long TE for hepatic angioma, which appears as a relative hypersignal). After the first echo is obtained, there is a free interval until the next TR. The purpose of this study was to compare the image quality of turbo spin echo(TSE) diffusion-weighted imaging (DWI) and echo-planar imaging (EPI) of the oral cavityregion. This retrospective study included 26 patients who had undergone both TSE- and EPI-DWI. Misregistration of DWIwith T2-TSEimages was assessed in the oral cavity. 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.

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. 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.
