Diffusion tensor imaging of articular cartilage at 3T correlates with histology and biomechanics in a mechanical injury model.

We establish a mechanical injury model for articular cartilage to assess the sensitivity of diffusion tensor imaging (DTI) in detecting cartilage damage early in time. Mechanical injury provides a more realistic model of cartilage degradation compared with commonly used enzymatic degradation.

A robust diffusion tensor model for clinical applications of MRI to cartilage

Diffusion tensor imaging (DTI) of articular cartilage is a promising technique for the early diagnosis of osteoarthritis (OA). However, in vivo diffusion tensor (DT) measurements suffer from low signal‐to‐noise ratio (SNR) that can result in bias when estimating the six parameters of the full DT, thus reducing sensitivity. This study seeks to validate a simplified four‐parameter DT model (zeppelin) for obtaining more robust and sensitive in vivo DTI biomarkers of cartilage.

International skeletal society outreach in Argentina

From June 28th to 29th, 2013, the Argentinian ISS Outreach Program took place in collaboration with the Centro de Diagnóstico Dr. Enrique Rossi in the city of Buenos Aires. A total of 690 participants attended. In the following report, we analyze the actual radiologic situation in this South American country. Outreach programs in a country such as Argentina are extremely valuable, as they provide a great opportunity for physicians that cannot travel overseas an attend international meetings such as RSNA, International Skeletal Society, or ARRS.
