Laufende Entwicklungen in der muskuloskelettalen Bildgebung an unserem Hochfeld-MR-Zentrum
Unser Schwerpunkt liegt auf der Weiterentwicklung der quantitativen Hoch- und Ultrahochfeld-MRT für Gewebe des Bewegungsapparats, einschließlich Knorpel und Sehnen, unter Verwendung von Techniken wie T2/T2*-Mapping, GAG-CEST, Natrium-MRT und Texturanalyse.
Darüber hinaus entwickeln wir automatisierte Analysemethoden und führen Langzeitstudien zum Fortschreiten der Arthrose durch, um die Standardisierung und den diagnostischen Wert in der Bildgebung des Bewegungsapparats zu verbessern.
Unser Team ist ständig auf der Suche nach neuen Mitgliedern. Kontaktieren Sie Vladimir Juras, wenn Sie interessiert sind!
