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.
