However, a decrease in olfactory thresholds has not been used as an index for olfactory nerve damage in patients. The authors assessed peripheral olfactory nerve viability by performing combined SPECT-CT after nasal administration of Tl-201 to determine whether olfactory nerve was damaged in patients with olfactory impairments in comparison to healthy volunteers. It was found that nasal Tl-201 migration to the olfactory bulb was significantly lower in the patients with head trauma, respiratory infection, and chronic rhinosinusitis than in healthy volunteers.
