3T MR articular cartilage maps prove their worth
With the incidence of arthritis and other musculoskeletal diseases set to double in the next two decades, clinicians will welcome new quantitative 3T MRI strategies for assessing cartilage and chondral lesions.
With the incidence of arthritis and other musculoskeletal diseases set to double in the next two decades, clinicians will welcome new quantitative 3T MRI strategies for assessing cartilage and chondral lesions.
Two approaches have shown progress, said Dr. Bruce Forster, an associate professor of radiology at the University of British Columbia in Vancouver. One involves T2 mapping sequences that can evaluate the integrity and orientation of a collagen network. The other is a T1/T2 delayed gadolinium-enhanced MRI of cartilage (dGEMRIC). It is sensitive to changes in the proteoglycan content of cartilage, he said.
A multicenter study by European researchers demonstrated that T2 mapping performed on a 3T scanner can monitor the success of autologous cartilage transplantation (Invest Radiol 2007;42[6]:442-448). A separate study by Finnish researchers concluded that the combination of T2 mapping and T2 dGEMRIC imaging may be better than either approach alone for tracking cartilage repair (Osteoarthritis Cartilage 2007;15[4]:372-378).
"Our lab is assessing a commercial product for its utility in cartilage imaging, which can be read quickly and easily coregistered with anatomic images." Forster said.
FDA Grants Expanded 510(k) Clearance for Xenoview 3T MRI Chest Coil in GE HealthCare MRI Platforms
November 21st 2024Utilized in conjunction with hyperpolarized Xenon-129 for the assessment of lung ventilation, the chest coil can now be employed in the Signa Premier and Discovery MR750 3T MRI systems.
New Study Examines Agreement Between Radiologists and Referring Clinicians on Follow-Up Imaging
November 18th 2024Agreement on follow-up imaging was 41 percent more likely with recommendations by thoracic radiologists and 36 percent less likely on recommendations for follow-up nuclear imaging, according to new research.
