Reduktion von Metallartefakten in der muskuloskelettalen Bildgebung

Gelenkprothesen und andere orthopädische Implantate werden bei vielen Patienten mit muskuloskelettalen Erkrankungen eingesetzt. Während diese Operationen häufig ein gutes klinisches Ergebnis zeigen, sind im Verlauf bei vielen Patienten radiologische Untersuchungen notwendig. Orthopädische Implantate führen jedoch in der MRT und der CT zu starken Metallartefakten. Dieser Artikel stellt mehrere grundlegende Methoden sowie fortgeschrittene Techniken zur Reduktion dieser Artefakte für MRT und CT vor, um eine diagnostische Untersuchung bei Patienten mit Metallimplantaten zu ermöglichen. MRT und CT werden so zu wichtigen und zuverlässigen Modalitäten, um Patienten mit Gelenkprothesen und orthopädischen Implantaten zu untersuchen.
