Musculoskeletal Imaging
Robust Musculoskeletal Imaging Musculoskeletal (MSK) imaging is a rapidly expanding imaging segment with projected growth due to escalating obesity and aging patient population in the US. MSK injuries and conditions can lead to disability and chronic disease states in patients, making confident and early diagnosis beneficial to long term health and health care cost reduction. MSK imaging ranges from very small field of view for areas including fingers and toes to larger areas such as hips and spines. The diversity of imaging requirements makes consistent image quality both a challenge and a fundamental requirement for all imaging departments. MRI, a critical diagnostic tool for evaluating the complex MSK anatomies and pathologies, provides high signal to noise (SNR), high spatial resolution, and unmatched contrast differentiation. Advanced imaging capabilities have a proven impact to positive clinical outcomes, establishing MRI as a viable alternative to arthroscopic diagnostic procedures, and has enabled positive modification of the treatment plan for patients with early stages of arthritis. To support the diverse demands of MSK imaging, service providers are looking for comprehensive MRI capabilities that include: A versatile imaging suite for high quality imaging including thin slice, small field of view imaging with high SNR and CNR Isotropic imaging capability for reconstructing data sets into any plane to visualize challenging intricate anatomical structures Comprehensive cartilage assessment using unique imaging acquisitions and sophisticated analysis capabilities Uniform fat suppression for all anatomy and all FOV s to visualize intricate MSK structures obstructed by signal from bone Dedicated anatomically specific coil technology to provide high uniformity, anatomical coverage and SNR Echelon Oval provides the full spectrum of the leading musculoskeletal imaging capabilities, including image acquisition features with uniform fat suppression across a range of anatomies and FOV s, and unique cartilage imaging capabilities.
