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.

Study Says Contrast-Enhanced Mammography Offers Comparable Breast Cancer Detection to MRI
November 15th 2023In findings from an enriched cohort of asymptomatic patients with screening-detected abnormalities, researchers found that contrast-enhanced mammography (CEM) was superior to conventional mammography and offered equivalent detection of breast cancer in comparison to breast MRI and abbreviated breast MRI.
