Zusammenfassung

Im klinischen Alltag erfolgt die Knorpeldarstellung an den verschiedenen Gelenken mittels Magnetresonanztomographie (MRT), die sich als nicht-invasive bildgebende Technik dazu bestens eignet. Obwohl bis heute die morphologische Beurteilung im Vordergrund steht, so scheint der Zeitpunkt nahe, an dem mittels MRT auch effiziente Aussagen über strukturelle Eigenschaften, Zusammensetzung bzw. pathologische Veränderungen der Knorpelstruktur möglich sein werden. Darüber hinaus erlaubt die MRT auch die Darstellung von subchondralen Knochenlagerveränderungen (reaktives Knochenmarködem, Mikrofrakturen, Fettmarkskonversionen, Osteonekrosen und Zysten), die der direkten arthroskopischen Draufsicht und auch bei der Arthroskopie verborgen bleiben. Die MRT ermöglicht somit wie kein anderes Verfahren genaue Aussagen über die osteochondrale Funktionseinheit. In diesem Kapitel werden die Struktur des hyalinen Gelenkknorpels sowie die Möglichkeiten und Grenzen der Knorpeldarstellung mit den verschiedenen MRT-Sequenzen beschrieben.
