“…The standard sequences for knee joint imaging are fatsaturated IM-or T2-w FSE sequences. These sequences allow excellent visualization of the hyaline cartilage, menisci, tendons and ligaments as well as the capsular structures of the joint and the bone marrow [1][2][3][4][5]17]. A potential disadvantage of these sequences is the relatively large slice thickness (2-4 mm) with an interslice gap; thus, partial volume effects limit visualization of small structures, and 3D reformations are not possible.…”

“…These sequences have demonstrated good performance in detecting joint abnormalities such as meniscal tears [1,2], ligament injuries [3] or cartilage damage [4,5]. Limitations of these sequences, however, have to be considered.…”

“…Limitations of these sequences, however, have to be considered. These include: (1) relatively thick image sections with gaps and partial volume effects, (2) non-isotropic voxels and (3) acquisition of 2D sequences in all three planes, since reformations are not possible, thus increasing examination time. Using isotropic 3D T2-or IM-weighted techniques may solve these problems and potentially optimize visualization of knee abnormalities.…”

Isotropic 3D fast spin-echo imaging versus standard 2D imaging at 3.0 T of the knee-image quality and diagnostic performance Abstract The objective of this study was to compare a newly developed fat-saturated intermediate-weighted (IM-w) 3D fast spin-echo (FSE) sequence with standard 2D IM-w FSE sequences regarding image quality and diagnostic performance in assessing abnormal findings of the knee. MR imaging was performed at 3.0 T in 50 patients. Images were assessed independently by three radiologists. Image quality was rated significantly higher (p<0.05) for the 2D versus the 3D FSE sequences. Sensitivity for cartilage lesions was slightly higher for the 3D sequence, but specificity was lower. Low contrast objects were better visualized with 2D sequences, while high contrast objects were better shown with the 3D sequence. Confidence scores were higher for 2D than for 3D sequences, but differences were not significant. In conclusion, isotropic 3D FSE IM-w imaging may enhance standard knee MRI by increased visualization of high contrast lesions; however, 3D FSE image quality was lower.

“…Secuencias 3D FSE (Fast Spin Echo) con resolución isotrópica corresponden a otro método promisorio para reemplazar las secuencias 2D en la práctica clínica. Secuencias 3D FSE permiten obtener imágenes en densidad protónica, la secuencia más comúnmente utilizada en RM músculo-esquelética (7,(8)(9)(10)(11)(12)(13)(14)(15)(16) . La gran ventaja de esta secuencia es su resolución espacial, siendo posible obtener reconstrucciones multiplanares en ejes arbitrarios, hecho que favorece la interpretación (Figura 4).…”

“…Studies by Dixon (1996), Escobedo et al (1996), Mackenzie et al (1996a,b), Cheung et al (1997) and Dorsay and Helms (2003) have shown that it is effective in a wide range of clinical settings. The recent introduction of 3-T magnets has enabled higher resolution images of the knee with elegant demonstrations of both normal anatomy and pathology as demonstrated by Gold et al (2004a).…”

High resolution imaging of the knee on 3‐Tesla MRI: A pictorial review

et al. 2008

View full text Add to dashboard Cite

The recent introduction of 3-Tesla MRI offers substantial advances in musculoskeletal applications. High resolution images can now be obtained with shorter data acquisition times. This article provides a pictorial review of 3-Tesla imaging in the knee with descriptions of both normal anatomy and the more common lesions involving the menisci, ligaments, and articular cartilage. A discussion of the issues associated with imaging at higher field strengths is also included.
