Weight-Bearing MRI Literature
Lumbar disc nomenclature: Recommendations of the combined task forces of the North American Spine Society, the American Society of Spine Radiology and the American Society of Neuroradiology
The article provides a discussion of the recommended diagnostic categories pertaining to the lumbar disc: normal; congenital/developmental variation; degeneration; trauma; infection/in-flammation; neoplasia; and/or morphologic variant of uncertain significance. The article provides a glossary of terms pertaining to the lumbar disc, a detailed discussion of these terms, and their recommended usage. Terms are described as preferred, nonpreferred, nonstandard, and colloquial. Updated illustrations pictorially portray certain key terms. Literature references that provided the basis for the task force recommendations are included.
Incorporating Weight-Bearing MRI Into Spine Practices: Q&A With Dr. Douglas Smith of Musculoskeletal Imaging ConsultantsApril 02, 2013|written by Laura Miller
Douglas Smith, MD, founder of Musculoskeletal Imaging Consultants, discusses what it takes to incorporate weight-bearing MRI into spine practices.
Q: How can weight-bearing MRI be incorporated into the surgeon’s practice?
Dr. Douglas Smith: Weight-bearing MRI such as the Esaote G-scan Brio provides a cost effective MRI solution for orthopedic and spine practices that desire an in-office MRI unit that excels in the spine but can also examine the hip, shoulder and remainder of the joints with high quality. The price and operating costs are less that 1/3 of other comparable technology on the market.
Q: What are the advantages of using weight-bearing technology over other types of MRI?
DS: Patients more frequently experience pain from nerve root compression or instability, spinal stenosis, or instability when the patient is standing or weight-bearing than when recumbent and research and European experience have shown 20 to 30 percent larger or more frequent findings with weight-bearing than non-weight-bearing position. Fast cine flexion-extension views can also be performed of the cervical spine. The newer technology includes high efficiency surface coils that produce images of similar quality to high field strength magnets at a much more favorable price point.
