“…Alternatively, MR arthrography could demonstrate the presence and integrity of the ligaments assessed by ultrasound [6,17]. Recently, MR evaluation of wrist ligaments with three-dimensional sequences has been proposed [18], but this investigation was not performed in our series. Finally, we did not perform a power Doppler evaluation of the ligaments and of the adjoining synovial tissue.…”

• Ultrasound is increasingly used to evaluate normal anatomy of extrinsic wrist ligaments. • Extrinsic wrist ligaments are thinner in rheumatoid arthritis patients than in controls. • Extrinsic wrist ligaments are less easy to detect in rheumatoid arthritis patients. • Ligament thinning and detectability are not related to clinical parameters.

“…With the development of 3 T MR systems and 8-16 channel coils, three-dimensional (3D) sequences have shown to be more effective in analyzing carpal ligaments. Three-dimensional MRI techniques can produce much thinner contiguous slices than standard 2D sequences and their improved spatial resolution as well as the multiplanar reconstruction possibilities allow better visualization of small complex anatomical structures such as the palmar and dorsal carpal ligaments [34,35]. Because most of the carpal ligaments have an oblique or curved course in 3D space, they often cannot be depicted in their entirety from origin to insertion, and image interpretation is based on the summation of adjacent MR slices.…”

Advanced imaging of the scapholunate ligamentous complex

et al. 2015

The scapholunate joint is one of the most involved in wrist injuries. Its stability depends on primary and secondary stabilisers forming together the scapholunate complex. This ligamentous complex is often evaluated by wrist arthroscopy. To avoid surgery as diagnostic procedure, optimization of MR imaging parameters as use of three-dimensional (3D) sequences with very thin slices and high spatial resolution, is needed to detect lesions of the intrinsic and extrinsic ligaments of the scapholunate complex. The paper reviews the literature on imaging of radial-sided carpal ligaments with advanced computed tomographic arthrography (CTA) and magnetic resonance arthrography (MRA) to evaluate the scapholunate complex. Anatomy and pathology of the ligamentous complex are described and illustrated with CTA, MRA and corresponding arthroscopy. Sprains, mid-substance tears, avulsions and fibrous infiltrations of carpal ligaments could be identified on CTA and MRA images using 3D fat-saturated PD and 3D DESS (dual echo with steady-state precession) sequences with 0.5-mm-thick slices. Imaging signs of scapholunate complex pathology include: discontinuity, nonvisualization, changes in signal intensity, contrast extravasation (MRA), contour irregularity and waviness and periligamentous infiltration by edema, granulation tissue or fibrosis. Based on this preliminary experience, we believe that 3 T MRA using 3D sequences with 0.5-mm-thick slices and multiplanar reconstructions is capable to evaluate the scapholunate complex and could help to reduce the number of diagnostic arthroscopies.

“…30 The thinnest slice thicknesses obtainable, typically 0.6 to 1.2 mm, are acquired through volumetric 3D pulse sequences. 19,21,22,24,28,72,80,81 Initially these volumetric acquisitions were of the gradient echo (GRE) variety, resulting in T2*-weighted images, and thought to be most useful for assessing the interosseous ligaments because of the thin sections obtainable. 26,84 However, more recently, isotropic 3D FSE sequences have become available, which have superior SNR, in addition to the usual isotropic 3D acquisition benefits of ability to reconstruct data into any arbitrary plane with thin slice thickness.…”

“…68 Thin high-resolution images are required to evaluate the small ligaments of the wrist, which often take a double-oblique course in threedimensional (3D) space. 19 In order to achieve the requisite spatial resolution, a high SNR is required, and is achieved primarily through the use of an appropriate local receiver coil. 16,70,71 There are many different acceptable surface coil design options.…”
