OVERVIEW |
|
OVERVIEW Motion is still an unsolved problem in MR and is a dominant source of artifacts. Motion can result in prolonged or diagnostically inadequate studies, and in some cases requires the use sedation or general anesthesia. The decreased patient comfort and through-put is inconvenient for both the patient and the clinicians, and can be significantly more costly. The objective of this workshop is to bring specialists from different disciplines together and to provide a broader view, as well as detailed information about how various forms of motion can affect MR data; how motion can be detected; how to deal best with motion-corrupted data; what can be done to prevent MR data from being corrupted by motion; what new products and technologies are available to address these problems, and how to facilitate the translation of these new developments from bench to bedside. AUDIENCE DESCRIPTION This workshop is designed for: • MR Physicists and Engineers • Physicians challenged by motion problems in MR EDUCATIONAL OBJECTIVES Upon completion of this workshop, participants should be able to: · Describe sources of motion and their consequences on the MR scans; · Implement simple measures to mitigate motion artifacts; · Compare strengths and weaknesses of retrospective and prospective motion correction approaches; · Describe challenges arising from patient motion for different body regions/subspecialities (neuro, body, MSK, pediatrics, spectro); · Determine pose changes and elastic deformation with MR navigators and other external probes; and · Implement algorithms for rigid and non-rigid image registration and pattern recognition methods to determine pose changes. |
