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

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. INTRODUCTION. 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 has been demonstrated as a means of addressing high RF power deposition and modulation transfer function (MTF) distortion due to relaxation (1-12).

Fast spin-echo imaging of the brain and spine - PubMed.

The use of fast or turbo spin echo (FSE, TSE) imaging has become routine in MRI today. A spin echo sequence employs a 180° RF pulse (typically) to create the echo, which also corrects for dephasing effects from slight field inhomogeneities and chemical shift. In a conventional spin echo sequence, a phase encoding gradient of defined amplitude. Fast spin echo a spin echo pulse sequence in which 4-16 echoes are obtained for each excitation, reducing scan time proportionately; each echo is separately phase encoded.

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.

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. This is done by applying new 180° pulses to obtain a spin.

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,.

The prescan as recited in claim 1 which includes: 5) adjusting the value of a magnetic field gradient in the fast spin echo pulse sequence to reduce the difference in slope of the two phase profiles; and. 6) repeating steps 1, 2 and 5 until the difference in slope of the two phase profiles is less than a preset amount. 3.

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

Fast Spin-Echo Pulse Sequence A fast spin-echo (FSE) sequence uses a different phase encoding gradient for each echo generated. More than one line of k-space is completed per TR (2). The echo train length (ET) is the number of 180-degree pulses applied after the initial pulse. Increasing the ET decreases the. Sekuen Fast Spin Echo memiliki keuntungan dibandingkan akuisisi citra dengan sekuen spin echo, yaitu kekebalan dari medan magnet eksternal dengan waktu akuisisi 4X, 8X, hingga 16X lebih cepat.. Namun, setiap echo mengalami jumlah peluruhan T2 intrinsik yang berbeda, yang menghasilkan perbedaan kontras citra bila dibandingkan dengan spin echo konvensional dari TR dan TE yang serupa.

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.

T2 Mapping from Super-Resolution-Reconstructed Clinical Fast Spin Echo.

Background This work was conducted to assess the diagnostic efficiency of isotropic three-dimensional VISTA-fast spin echo versus standard two-dimensional fast spin echo at 1.5 T MRI, in the assessment of internal knee derangement in symptomatic patients, aiming to obtain similar diagnostic accuracy in a shorter time span, with reduction of partial volume artifacts by thin continuous sections. In clinical fetal brain magnetic resonance imaging routine, 2D low-resolution T2-weighted fast spin echo sequences are used to minimize the effects of unpredictable fetal motion during acquisition. As super-resolution techniques make it possible to reconstruct a 3D high-resolution volume of the fetal brain from clinical low-resolution images. 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.

Measuring spin-spin relaxation by using long TR and TE times Higher signal for more water content; Low signal for fat − Note that this only applies to standard Spin Echo (SE) sequences and not the more modern Fast Spin Echo (FSE) sequence (also referred to as Turbo Spin Echo, TSE), which is the most commonly used technique today. In FSE/TSE.

Fast spin echo (FSE), a variant of the rapid acquisition with refocused echoes pulse sequence, is now being widely considered as an alternative to conventional spin echo for proton density and T2-weighted imaging. Although the medical experience with this sequence is relatively limited, relevant aspects of the technique have been well. We evaluated an alternative T2-weighted fast spin-echo pulse sequence that emphasizes tissue-free fluid. Methods: We prospectively used high-resolution, surface coil technique for orbital MRI at 1.5T in 21 orthotropic and 113 living strabismic subjects and 2 monkey cadavers by using T2 fast spin-echo (T2FSE) weighting (long repetition time. Fast Spin Echo. Fast imaging sequences based on trains of spin echoes, like RARE, require a separate phase encoding pulse before each echo, compensated by an opposite pulse after each echo to maintain the Carr‐Purcell‐Meiboom‐Gill (CPMG) conditions ().Timing constraints usually force these pulses to be short and thus relatively high with respect to the readout and slice selection gradients.
