Purpose To compare a three-dimensional (3D) T2-weighted turbo spin-echo (TSE) magnetic resonance (MR) sequence (VISTA; Philips Medical Systems, Best, the Netherlands) with a two-dimensional (2D) T2-weighted TSE sequence in terms of image quality, signal intensity (SI) difference ratios, conspicuity, and staging of uterine tumors. Materials and Methods This retrospective study was approved by.

Fast T 2 mapping using multi-echo spin-echo MRI: A linear order.

SUMMARY: Diagnosis of acquired middle ear cholesteatoma on MR imaging is mostly done on late postgadolinium T1-weighted MR images and/or echo-planar (EPI) diffusion-weighted (DWI) MR images. We describe the appearance of a case of a complicated attical middle ear cholesteatoma on single-shot (SS) turbo spin-echo (TSE) DWI compared with EPI-DWI. This case suggests a higher reliability of SS TSE.

Introduction: For the conventional phase-encoding method used with turbo/fast spin-echo (TSE) imaging, echoes from a given excitation are allocated in an interleaved fashion to a specific line of k space along one phase-encoding direction. This approach becomes very inefficient for 3D-TSE imaging. Turbo Spin Echo (TSE) method is widely used for an MR examination. However, the periodical motion artifacts such as a throb of the bloodstream, the cerebrospinal fluid and patient's moving are much observed in TSE image than the conventional Spin Echo (conv.SE) image and the Gradient Echo (GrE) image. This originates in k-space trajectory peculiar to TSE method. Randomized Phase Encoding TSE.

High‐resolution turbo spin echo (TSE) images have demonstrated important details of carotid artery morphology; however, it is evident that pulsatile blood and wall motion related to the cardiac cycle are still significant sources of image degradation. Although ECG gating can reduce artifacts due to cardiac‐induced pulsations, gating is rarely used because it lengthens the acquisition time.

Balanced steady-state free precession MRCP is a robust alternative to.

On the other hand, if the echo train is formed by radiofrequency pulses, such as turbo spin-echo (TSE)/fast spin-echo (FSE) based acquisition, 10 the effect of static field inhomogeneities will be refocused, increasing the signal at a given echo time and permitting longer sampling windows, higher voxel bandwidths and less spatial distortion. Spin-echo and turbo spin-echo imaging had identical specificities (90%) and similar sensitivities (88% and 82%, respectively). This study shows that proton density-weighted sequences with an echo train length of five preserve sufficient high-spatial-frequency information to provide performance similar to that of conventional spin-echo sequences.

Spin-echo pulse sequences are one of the earliest developed and still widely used (in the form of fast spin echo) of all MRI pulse sequences. The pulse sequence timing can be adjusted to give T1-weighted, proton density,. Turbo Spin Echo (TSE) imaging, also known as Fast Spin Echo (FSE) imaging are based on the RARE (Rapid Acquisition with Refocused Echoes) technique. The TSE sequence (illustrated above) resembles a conventional spin echo sequence in that it uses a series of 180°-refocusing pulses after a single 90°-pulse to generate a train of echoes. The TSE.

Purpose 2D turbo‐spin‐echo (TSE) is widely used in the clinic for neuroimaging. However, the long refocusing radiofrequency pulse train leads to high specific absorption rate (SAR) and alters the contrast compared to conventional spin‐echo.

Usefulness of turbo spin-echo MR imaging in the evaluation of.

T2-weighted images were acquired in three orthogonal planes at each field strength using a turbo spin-echo sequence. Fifty neuroanatomic structures were identified and evaluated on the 7T MR images; subsequently, those were found on the 3T and 45 out of the 50 structures were detected on the 1.5T imaging.

Imaging Mastery Series: Benign Liver Lesions, presented by Dr. Mahan MathurCT serve. The turbo spin echo (TSE) method is an alternate approach for performing DWI. Because TSE-DWI uses a 180° RF refocusing pulse for each measured echo, susceptibility artifacts are smaller and image distortion is less marked than with EPI-DWI. While a lower signal-to-noise ratio. Black blood turbo spin echo (TSE) imaging of the right ventricle (RV) free wall is highly sensitive to cardiac motion, frequently resulting in nondiagnostic images. Temporal and spatial parameters of a black blood TSE pulse sequence were evaluated for visualization of the RV free wall. Seventy-four patient studies were retrospectively evaluated.

Three-dimensional (3D) turbo spin-echo (TSE) images have been used in imaging of the extremities and comparable diagnostic performance to two-dimensional (2D) TSE images has been reported in several studies. However, comparison of the 3D isotropic TSE intermediate-weighted sequence and 3D FFE sequence in terms of image quality has not been.

High-Resolution Simultaneous Multi-Slice Accelerated Turbo Spin-Echo.

To evaluate the reproducibility of three-dimensional turbo spin-echo (3D-TSE) and two-dimensional dual inversion-recovery turbo spin-echo (2D-DIR-TSE) for coronary vessel wall imaging in KD. Ten. Our 2D multislice turbo spin-echo sequence combined with a driven equilibrium pulse provides a bright signal of joint fluid with otherwise unchanged signal intensities as compared with a normal T1-weighted turbo spin-echo sequence at high spatial resolution and short scan times. Thus, it might represent a useful adjunct for routine joint. When the spins are rephased, they become coherent, and thus signal (or "echo") is generated to form images. Unlike spin echo, gradient echo does not need to wait for transverse magnetisation to decay completely before initiating another sequence, thus it requires very short repetition times (TR), and therefore to acquire images in a short time.

Purpose. To obtain high-quality T 2 ′ $$ {\mathrm{T}}_2^{\prime } $$ maps of brain tissues from water-unsuppressed magnetic resonance spectroscopic imaging (MRSI) and turbo spin-echo (TSE) data.. Methods. T 2 ′ $$ {\mathrm{T}}_2^{\prime } $$ mapping can be achieved using T 2 * $$ {\mathrm{T}}_2^{\ast } $$ mapping from water-unsuppressed MRSI data and T 2 $$ {\mathrm{T}}_2 $$ mapping from. Methods: A stack-of-stars turbo spin echo pulse sequence with variable refocusing flip angles and a flexible pseudorandom view ordering is proposed for simultaneous T2-weighted imaging and T2 mapping. An analytical framework is introduced for the selection of refocusing flip angles to maximize relative tissue contrast while minimizing T2.
