Heavily T2-weighted 3D fast asymmetric spin-echo images were obtained with a voxel size of 0.3 × 0.3 × 0.8 mm without zero-fill interpolation. Two radiologists traced the areas of the EED and EES manually, and the volume was calculated.... Honjo I, Takagi A, Azato R. Magnetic resonance imaging of patients with large vestibular aqueducts.

2.2. MRI Sequence and Parameters. Two T 1-weighted sequences (spin echo and fast spin echo) were used at two different field strengths (1.5 T and 3 T), both GE HDx systems at 16.0 software platform and with transmit/receive head coils with identical designs.Typical scan parameters at 1.5T were TR = 200 ms/TE 12 ms/excitation flip angle 90°/refocusing flip angle = 180° or 120°/number of. If we acquire T2 weighted imaging with just a Spin Echo Imaging, then scan time will get longer compared to the fast spin echo. But the problem of this fast spin echo imaging is that until acquiring the desired echo, we keep acquiring multiple echoes. By applying for multiple 180 degree RF pulses, as shown in the previous slide.

Figure 19-1. A spin-echo PSD with eight echoes. The echo spacing ( ESP) is 17 msec. Thus, for each k-space in CSE, we repeat the TR 256 times.

3 rows. 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,.

Gradient Spin Echo (GraSE) imaging for fast myocardial T2 mapping.

Three-dimensional isotropic T2-weighted fast spin-echo (VISTA) knee MRI at 3.0 T in the evaluation of the anterior cruciate ligament injury with additional views: comparison with two-dimensional fast spin-echo T2-weighted sequences. Acta Radiol (2015 Jan 13) pii: 0284185114568048. [Epub ahead of print]. Spin echo and fast spin echo based low SAR sequences provided acceptable image quality with comparable image blooming (enlargement) of stimulator leads. The mean lead diameters were 2.2 ± 0.1mm for 2D, 2.1 ± 0.1mm for 3D, and 4.0 ± 0.2mm for 3D MPRAGE sequence.... Utilizing Fast Spin Echo MRI to Reduce Image Artifacts and Improve Implant. Fast spin echo (FAISE or FSE, ref 65bis), also called turbo spin echo (TSE) is an MRI sequence that results in fast scan times. In this sequence, several 180 refocusing radio-frequency pulses are delivered during each echo time (TR) interval, and the phase-encoding gradient is briefly switched on between echoes.

With this type of sequences, a slice can be made in under a second. Duration of an ultrafast spin echo sequence Duration = TE • number of phase encodings to acquire Interest and limits These sequences are well adapted to imaging non-circulating liquid structures appearing as a T2-weighted hypersignal (Cholangio-MRI and Uro-MRI).

MRI in practice 5th edition Chapter 3 - spin echo sequence.

Fast spin-echo (SE) sequences are routinely used in clinical MRI to achieve T2 weighting. Compared with conventional fast SE sequences, single-shot fast SE sequences acquire the whole two-dimensional k-space in a single echo train ( 1 ), resulting in much faster acquisition compared with conventional fast SE.

Nevertheless, patient movement is often a problem in MRI and only very fast acquiring techniques as described in 4.1 and 4.3 can solve this. Blood flow is a special case, where venous blood shows up bright in T2 weighted spin echo examinations, while rapidly flowing arterial blood appears.

Fat‐saturation FSE imaging can effectively replace CSE imaging in the evaluation of rotator cuff pathology, according to the extent of partial‐thickness tears. 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.

Standard Spin Echo (SE) magnetic resonance imaging (MRI) is known to be a very sensitive method for the detection of bone metastases and in comparison to skeletal scintigraphy, MRI detects more lesions when field of view includes the area of suspicion. However, only with the introduction of new fast SE sequences, have MRI protocols, for the detection of metastases, become rapid enough to make. In an MRI system a fast spin echo pulse sequence is employed to acquire data for producing an image. The phase of successive RF refocusing pulses in the sequence is shifted by a sweep factor and an.

Comparison of fat‐saturation fast spin echo versus conventional spin.

Magnetic resonance imaging (MRI) using a fast spin echo protocol (FSE) gives greatly improved spatial resolution for the inner ear and its central connections. Excellent contrast resolution between bone, neural tissue and intracranial fluids is obtained on the heavily T2 weighted images.
