Delayed contrast MR may predict rheumatoid arthritis
Delayed gadolinium enhancement during MR imaging of cartilage of the metacarpophalangeal joints in patients with rheumatoid arthritis is feasible at 3T and may help predict rheumatoid arthritis.
Delayed gadolinium enhancement during MR imaging of cartilage of the metacarpophalangeal joints in patients with rheumatoid arthritis is feasible at 3T and may help predict rheumatoid arthritis.
The procedure involves T1 mapping following intravenous contrast. Concentration of the contrast in cartilage is an indirect measure of glycosaminoglycan (GAG), a component of hyaline cartilage.
The absence of GAG during delayed-contrast MR may help assess cartilage degeneration in the morphologically normal-appearing second and third metacarpophalangeal joints in patients.
Phalangeal and metacarpal delayed-enhancement values in patients with rheumatoid arthritis were significantly lower than in control subjects, although joint thickness was comparable in both groups, according to the researchers. Cartilage damage is a common occurrence in rheumatoid arthritis patients, so imaging may help for diagnosis and treatment purposes (Radiol 2010;257:441-447).
Can AI Enhance CT Detection of Incidental Extrapulmonary Abnormalities and Prediction of Mortality?
September 18th 2024Emphasizing multi-structure segmentation and feature extraction from chest CT scans, an emerging AI model demonstrated an approximately 70 percent AUC for predicting significant incidental extrapulmonary findings as well as two-year and 10-year all-cause mortality.
Comparing Digital Breast Tomosynthesis to Digital Mammography: What a Long-Term Study Reveals
September 17th 2024In a study involving over 272,000 breast cancer screening exams, digital breast tomosynthesis (DBT) had a higher breast cancer detection rate and a lower rate of advanced cancer presentation at the time of diagnosis in comparison to digital mammography.
