MRI of the knee is traditionally done with multiple 2D multislice acquisitions.Fast spin-echo (FSE) is commonly used to provide intermediate or T2-weighted images in a reasonable scanning time. These images are useful to look for internal derangements such as meniscal tears [1, 2], ligamentous injury [], or cartilage damage [4, 5].Two-dimensional FSE has limitations in examination of the knee.
Isotropic MRI of the Knee with 3D Fast Spin-Echo Extended Echo-Train.
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 that time FSE/TSE has grown to become one of the "workhorse" pulse sequences used in virtually all aspects of modern. Mized fast/turbo spin-echo pulse sequences provide a robust and flexible approach for 3D spin-echo-based imag-ing with a broad range of clinical applications.

Spin echo v FSE - Questions and Answers in MRI.
Reducing and continuously varying the flip angle of the refocusing RF pulses in a rapid acquisition with relaxation enhancement (RARE; fast/turbo spin echo) sequence is a useful means of addressing high RF power deposition and modulation transfer function (MTF) distortion due to relaxation. A fast spin echo sequence is faster than a conventional spin echo pulse sequence because: A. Several echoes for each slice are collected during each TR period B. T2* contrast takes less time C. A shorter TR is used for fast spin echo D. A smaller pixel size is utilized. A. Several echoes for each slice are collected during each TR period.

In particular, "fast-spin-echo" (FSE) or "turbo-spin-echo" (TSE) pulse sequences, which are optimized derivatives of the RARE technique 1, find use for a broad spectrum of MRI applications because these methods combine the desirable properties of spin-echo-based acquisitions with the speed advantage of collecting multiple lines of phase. 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.

Stuber et al. (2001a) evaluated a threedimensional fast spin echo acquisition combined with navigator gating for coronary MRA. This resulted in the visualization of the coronary artery tree with. The RARE sequence is a fast spin echo sequence which utilizes RF refocused echoes generated from a Carr-Purcell-Meiboom-Gill sequence. Such fast spin echo ("FSE") scans are very susceptible to image artifacts caused by such things as eddy currents, B 0 instability, gradient amplifier infidelity, magnetic hysteresis and high order Maxwell terms. Although the reduction in measurement time using fast spin echo (FSE) technique is desirable (and plays a fundamental role in clinical imaging today), the very use of multiple closely spaced refocusing pulses is associated with higher RF power deposition. Thus, an FSE sequence may approach the acceptable limits of specific absorption rate (SAR.

FIGURE 22-4 The fast spin echo sequence is shown. In this rapid scan, several echoes are recalled, with each one contributing to a different line of k-space. For each echo recalled, a separate 180-degree refocusing pulse is applied in conjuction with the slice selection gradients. Each echo of the series contributes to a separate line of k. Generic diagram. The echo train technique can be pushed to the limit to fill the entire Fourier plane with a single 90° pulse (TR is thus infinite). These so-called « single-shot » sequences require the successive application of as many 180° pulses as there are k-space lines to fill. The sequence can be further accelerated, avoiding the. The RARE sequence is a fast spin echo sequence which utilizes RF refocused echoes generated from a Carr-Purcell-Meiboom-Gill sequence. Such fast spin echo ("FSE") scans are very susceptible to.

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).

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). 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 spin echo / dual echo sequence, the first echo is usually density and the second echo is T2 weighted image.
