“…This problem has been noted in previous research and may be accounted for in part by the long echo train and relatively long TE inherent in this sequence [10,[12][13][14]20]. Although the use of non-slice-selective refocusing pulses and variable flip angles with controlled signal evolution makes it possible to reduce the interecho spacing, the effective TE may still be long enough to introduce some blurring.…”

“…This lack of popularity may be attributed in part to long imaging times and use of gradient-echo techniques, which although yielding valuable information may involve signal and contrast patterns unfamiliar to interpreting radiologists. Three-dimensional volumetric imaging based on TSE techniques has been successfully implemented [10][11][12][13][14][15].With this approach, it is possible to perform a single acquisition with more traditional contrast patterns and isotropic voxels, allowing reformatting in arbitrary planes.In imaging of the shoulder, it is critical to be able to evaluate fine oblique structures that are extremely close to one another. For this reason, many radiologists advocate use of arthrography.…”

“…Since the introduction of 3D fast spin-echo (FSE)/turbo spin-echo (TSE) isotropic imaging techniques to the musculoskeletal imaging (5), diagnostic performance or image quality comparison study between the 3D isotropic imaging sequences and the conventional two-dimensional (2D) sequences has been executed by many investigators to elucidate its possibility as a substitute tool for the 2D sequences in various joints (4)(5)(6)(7)(8). Many studies thoroughly evaluated the diagnostic performance of shoulder and knee joints using 3D spine-echo isotropic imaging (6,7,(9)(10)(11).…”

Ankle is one of the most complex human joints and is vulnerable to injury (1, 2). Imaging numerous ligaments and tendons that run in various planes is sometimes challenging. To overcome this problems, three-dimensional (3D) acquisition magnetic resonance (MR) imaging techniques, that allows multiplanar reconstruction and reduces partial-volume Purpose : To compare the image quality and ligament traceability in ankle images obtained using Volume Isotropic Turbo Spin Echo Acquisition (VISTA) MRI with and without fat suppression. Materials and Methods:The signal-to-noise ratios (SNRs) in images from a phantom and from the ankle of a volunteer were compared. Ten ankles from 10 non-symptomatic volunteers were imaged for comparisons of contrast ratio (CR) and ligament traceability. All examinations were performed using VISTA sequences with and without fat suppression on a 3T MRI scanner. The SNRs were obtained from images with subjects and without subjects (noise-only).

Introduction To investigate the feasibility of using compressed sensing (CS) to accelerate three-dimensional fast spin-echo (3D-FSE) imaging of the knee. Methods A 3D-FSE sequence was performed at 3T with CS (CUBE-CS with 3:16 minute scan time) and without CS (CUBE with 4:44 minute scan time) twice on the knees of 10 healthy volunteers to assess signal-to-noise ratio (SNR) using the addition-subtraction method and once on the knees of 50 symptomatic patients to assess diagnostic performance. SNR of cartilage, muscle, synovial fluid, and bone marrow on CUBE and CUBE-CS images were measured in the 10 healthy volunteers. The CUBE and CUBE-CS sequences of all 50 symptomatic patients were independently reviewed twice by two musculoskeletal radiologists. The radiologists used CUBE and CUBE-CS during each individual review to determine the presence or absence of knee joint pathology. Student t-tests were used to compare SNR values between sequences, while kappa statistic was used to determine agreement between sequences for detecting knee joint pathology. Sensitivity and specificity of Cube and Cube-CS for detecting knee joint pathology was also calculated in the 18 symptomatic patients who underwent subsequent arthroscopic knee surgery. Results CUBE and CUBE-CS had similar SNR (p=0.15-0.67) of cartilage, muscle, synovial fluid, and bone marrow. There was near perfect to perfect agreement between CUBE and CUBE-CS for both radiologists for detecting cartilage and bone marrow edema lesions, medial and lateral meniscus tears, anterior cruciate ligament tears, effusions, and intra-articular bodies. Cube and Cube-CS had similar sensitivity (75.0%-100%) and specificity (87.5%-100%) for detecting 60 cartilage lesions, 20 meniscus tears, four anterior cruciate ligament tears, and four intra-articular bodies confirmed at surgery. Conclusions CS provided a 30% reduction in scan time for 3D-FSE imaging of the knee without a corresponding decrease in SNR or diagnostic performance.

Isotropic 3-Dimensional Fast Spin Echo Imaging Versus Standard 2-Dimensional Imaging at 3.0 T of the Knee

Abstract: Although the 3D FSE sequence performed better in depiction and characterization of cartilage abnormalities than the standard 2D FSE sequence, we currently do not recommend to use it as substitute. For the diagnosis of meniscal defects, however, no significant improvement was found.
