Comparison between conventional and fast spin-echo STIR sequences.

The fast spin-echo sequence is a spin-echo sequence, but with the time of the exam dramatically shorter than the conventional spin-echo. To understand how rapid the fast spin-echo sequence is, we should review how data is obtained in the conventional spin-echo.... However, the fat saturation techniques may be used to compensate for this.

Abstract The purpose of our study was to compare the value of respiratory-triggered fast spin-echo,... The protocol was composed of T2-weighted imaging with 1) a respiratory-triggered fat-suppressed fast spin-echo sequence (TR/effective TE = 6000-12000/85 msec, echo train length = 16, interecho spacing = 8.6 msec, received bandwidth = 31.2.

Gradient echo sequences (GRE) are an alternative technique to spin-echo sequence s, differing from it in two principal points: utilization of gradient fields to generate transverse magnetization; flip angles of less than 90° Compared to the spin-echo and inversion recovery sequences, gradient echo sequences are more versatile.

Fat Signal Suppression in Head and Neck Imaging Using Fast Spin-Echo.

The easiest way to identify T1 weighted fat saturated post gadolinium images is to look for adipose tissues (e.g. subcutaneous fat and fat in bone marrow) and blood vessels in the body (e.g arteries and veins in the brain, neck, chest, abdomen, upper limbs and lower limbs). Areas contain adipose tissues appear dark on T1 weighted fat saturated. Fast spin-echo: a magnetic resonance imaging technique that uses multiple spin-echoes to reduce imaging times in comparison to spin-echo imaging. See also spin-echo. Fast spin-echo (FSE) sequences are becoming popular for T2-weighted clinical imaging because they result in a severalfold reduction in imaging time and because they provide conventional spin-echo contrast for most tissues. Fat, however, has been observed to have anomalously high signal intensity on FSE images.

Comparison of conventional spin-echo and fast spin-echo magnetic.

Fast spin‐echo (FSE) sequences are becoming popular for T2‐weighted clinical imaging because they result in a severalfold reduction in imaging time and because they provide conventional spin‐echo contrast for most tissues. Fat, however, has been observed to have anomalously high signal intensity on FSE images. The purpose of this study was to compare the diagnostic performance of fat-saturation fast-spin-echo (FSE) T2-weighted (T2W) sequences with conventional spin-echo (CSE) T2W sequences in the detection of rotator cuff pathology using surgery as the reference standard. Oblique coronal dual-echo CSE and.

/ Semiquantitative assessment of focal cartilage damage at 3 T MRI A comparative study of dual echo at steady state (DESS) and intermediate-weighted (IW) fat suppressed fast spin echo sequences. In: European Journal of Radiology. 2011 ; Vol. 80, No. 2. pp. e126-e131. 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.... Because we produce multiple 180 degree pulses in such a short period of time, fat does not have time to decay properly and will contain high signal when we collect our echoes.

MRI sequence - Wikipedia.

SUMMARY: We present our initial experience with the use of a modified 3-point Dixon technique to obtain reliable fast spin-echo T1- and T2-weighted fat-suppressed images in the soft-tissue neck. The method has less sensitivity to magnetic field inhomogeneity than frequency-selective radiofrequency fat saturation and provides uniform fat suppression even near tissue-tissue and air-tissue.

Three-dimensional high-resolution fast spin-echo coronary magnetic.

T1 weighting occurs in a short TR spin echo sequence because of incomplete recovery of longitudinal magnetization. The T1 relaxation time, also known as the spin-lattice relaxation time, is a measure of how quickly the net magnetization vector (NMV) recovers to its ground state in the direction of B o. The return of excited nuclei from the high. Assessment of other structures in the knee with fast spin-echo proton-density fat saturation MRI provides good spatial resolution and adequate T2-weighted information. It may have advantages over the more heavily T2-weighted fast spin-echo T2 fat saturation and inversion recovery sequences. MeSH terms Adult Aged Aged, 80 and over. The typical MR imaging protocol included axial T1, axial proton density (fat sat), sagittal T1, sagittal T2 fast spin echo (fat sat), coronal T1, coronal T2 fast spin echo (fat sat) and coronal proton density (fat sat) sequences. Bipartite medial cuneiform: case report and retrospective review of 1000 magnetic resonance (MR) imaging studies.

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

• For fat-saturated spin-echo trains, fat recovers quickly • How does the recovering fat affect the signal in later echoes? • No signal! 272 • Any F0after an RF pulse is never refocused at an echo • Magnetization may accumulate, but does not affect the signal • Note dashed states B.Hargreaves - RAD 229 Intuition: Stabilization Pulse. In FSE, fat remains bright on a T2 due to the fast repetitions of 180 pulses. fat saturation, DIET (delayed interval echo train)... combination of a partial Fourier technique with fast spin echo; allows one to fill all the lines of k-space in one TR (half of the lines are filled and the other half are transposed); very short scan time, serious.

Gradient echo sequences | Radiology Reference Article.

Pulse sequences other than the conventional spin echo can also be used to measure T 2; gradient echo sequences such as steady-state free precession (SSFP) and multiple spin echo sequences can be used to accelerate image acquisition or inform on additional parameters. See also. Relaxation (NMR) Spin–lattice relaxation; Spin echo. This paper describes the technical aspects, characteristics and clinical applications of fat suppression in T2 weighted fast spin echo (FSE) sequences in neuroradiology. Fat suppression is essential with FSE as this sequence is characterized by a high fat signal not only in T1 but also in T2 weighted images leading to image artifacts in FSE.
