One of the problems with osteoarthritis has been diagnosing and monitoring the disease before symptoms become evident. It has therefore been difficult to change or delay the course of the disease. A few years ago, researchers from Lund University and Harvard Medical School developed a method to measure the degree of osteoarthritis using an MRI scanner, even at a very early stage. The method is called dGEMRIC (delayed gadolinium-enhanced MRI of cartilage).
The new method is described in Carl Siversson's thesis Three-dimensional T1 quantification techniques for assessment of cartilage quality using dGEMRIC: http://www.lunduniversity.lu.se/o.o.i.s?id=24732&postid=2064122 Eurekalert!
