세미나 제목 : New Techniques for Orthopedic MRI

발표초록 :

Osteoarthritis (OA) affects the majority of people at some point in their lives.  Magnetic resonance imaging (MRI) offers excellent soft-tissue contrast, as well as the flexibility to image different physical mechanisms.  MRI is therefore particularly useful for the study of OA.  Although there are numerous promising techniques, the double-echo steady-state (DESS) approach offers 3D imaging as well as ability to map T2 and diffusion in the short-T2 connective tissues including cartilage, meniscus and tendons.  The first part of this talk will cover the technical considerations of DESS, and provide imaging examples.

In late-stage OA, loss of cartilage can result in considerable pain, for which a common treatment is a total joint replacement.  Complications with joint replacements motivate post-operative imaging, where again the soft tissue contrast of MRI makes it useful.  Although MRI is safe for imaging many implanted devices, a number of image artifact mechanisms can result.  Recently several groups have made advances in techniques to substantially reduce such artifacts with so-called “multi-spectral imaging” (MSI) methods.  The second part of this talk will describe metal artifacts and different approaches to avoid these artifacts.
