2. Einführung Sowohl das Ergebnis der Übersichtsaufnahme als auch die klinische Verdachtsdiagnose entscheiden über den Einsatz möglicher Zusatzuntersuchungen. Den grössten Stellenwert besitzt dabei mittlerweile die Computertomographie. Ferner sind dies je nach Fragestellung: Angiographie Sonographie Szintigraphie oder Magnetresonanztomografie.
