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.
