Insbesondere bei nicht eindeutigen Ergebnissen der subjektiven und\/oder objektiven Olfaktometrie bedarf es zus\u00e4tzlicher objektiver Befunde, um St\u00f6rungen des Geruchssinns zu verifizieren. Anhand von Erfahrungen aus der Praxis und unter Ber\u00fccksichtigung der aktuellen Literatur ist dieser Artikel als eine Hilfestellung bei der Anfertigung radiologischer Zusatzgutachten zu verstehen. Dabei soll die Bedeutung einer umfassenden aktuellen Standardbildgebung einschlie\u00dflich einer Bulbusvolumetrie in Zusammenschau mit einer ausf\u00fchrlichen Anamnese und ggf. vorhandenen Vorbefunden betont werden. Neben der Dokumentation von Ver\u00e4nderungen der anatomisch am Geruchssinn beteiligten Strukturen, welche die beklagten St\u00f6rungen des Geruchssinns st\u00fctzen, kann durch spezielle neuroradiologische Untersuchungssequenzen zur Darstellung des Bulbus olfactorius, inklusive einer volumetrischen Messung desselben, ein objektiver Bestandteil f\u00fcr die Beurteilung von manchmal nur subjektiv vorhandenen St\u00f6rungen des Geruchssinns gewonnen werden.
