The simplest form of the spin-echo (SE) pulse sequence consists of 90°-pulse, a 180°-pulse, and then an echo. The time between the middle of the first RF pulse and the peak of the spin echo is called the echo time (TE). The sequence then repeats at time TR, the repetition time. Conventional (single echo) SE pulse sequence.

To determine whether turbo spin echo (TSE) sequences can replace conventional T2-weighted spin echo (SE) sequences in MRI of the liver, 40 patients with focal liver lesions were imaged at 0.5 T. A T2-weighted SE sequences (TR/TE 1800/90 ms, number of signals averaged [NEX]=2, scan time=7:16 min), a TSE sequence (TR/TE 1800/90 ms, NEX=4, number of echos per excitation=13, echo spacing=12.9 ms.

Advantages of a T1-Weighted Gradient-Recalled Echo (GRE) Sequence With a Radial 3D Sampling Approach Versus 2D Turbo Spin-Echo and Cartesian 3D GRE Sequences in Head and Neck MRI Article Jan 2020. Here we will discuss a way to modify the pulse sequence to get the same number of phase-encoding steps much faster - the fast spin echo sequence (FSE; sometimes called turbo spin echo or TSE). Remember that the spin echo occurs after proton dephasing is rephased by the 180-degree pulse.

Dec 08, 2017 · In conventional spin echo, 256 phase matrix selected so, 256 TR elapse to complete scan In fast spin echo, using turbo factor 16, 16 phase encoding steps are performed every TR. So 256÷16, scan time reduced to 1/16 of the original Conventional one line is filled per TR FSE several lines are filled per TR 12. Our aim was to evaluate the diagnostic reliability of turbo spin-echo (TSE) sequences compared to a conventional dual-echo spin-echo (SE) sequence in routine brain MRI at 1.0 T. The following demands were made on TSE sequences: acquisition time-reduction of at least 50% and true proton density (PD) contrast (lowsignal cerebrospinal fluid). A conventional spin-echo and two single-echo TSE.

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). The use of large echo train lengths. 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 MR imaging.

The acquisition of spin-echo images can be understood as follows: The patient is placed into the MRI machine. Once inside the machine all hydrogen ions in the different body tissues will align parallel with the magnetic field of the machine. Then, a coil emits RF pulses that cause the axis of these ions to change 90º.

TYPES Spin echo pulse sequences (spins are rephased by a 180 rephasing pulse): 1. Conventional spin echo 2. Fast or turbo spin echo 3. Inversion recovery. 4. Conventional Spin Echo Mechanism: Spin echo uses a 90° excitation pulse followed by one or more 180° rephasing pulses to generate a spin echo. PARAMETERS T 1 weighting Short TE 10.

We present the theoretical basis for active imaging with the dual spin-echo (DSE) dMRI pulse sequence, which is more complex than the standard sequence, but widely used due to its robustness to image distortion. The new formulation provides the basis for future active imaging studies using DSE.

As a general rule, images acquired with Fast or Turbo Spin Echo sequences (FSE/TSE) will result in images with fewer susceptibility artifacts than those acquired using gradient echo sequences. However, it is not always possible to replace gradient echo sequences with FSE sequences. Strategic selection of sequence parameters can be very effective.

The spin echo sequence preserves the MRI signal for longer with the addition of the 180° pulse as described previously. The second difference is the frequency-encoding gradient. A positive gradient is applied prior to the 180° RF pulse. This has the same effect as a negative FE gradient applied after the 180° pulse. Three-dimensional (3D) HR-MRI has been widely used for vessel wall imaging, offering the advantages of a large coverage volume and multi-planar imaging planes with whole coverage of intracranial arteries [5-9]. 3D turbo spin echo (3D TSE) imaging sequences with variable flip angle (FA) have been widely used for 3D HR-MRI vessel wall.

Liver diffusion-weighted MR imaging with L1-regularized iterative.

Mar 22, 2013 · For the spin echo sequence, this is realized by acquiring more than one echo per excitation pulse, whereat each echo is sampled with a different phase encoding value. This method is called the rapid acquisition with relaxation enhancement (RARE), turbo spin echo (TSE), or fast spin echo (FSE) sequence. The number of acquired echoes after one. 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.
