Item A Comparative Olfactory MRI, DTI and fMRI Study of COVID-19 Related Anosmia and Post Viral Olfactory Dysfunction(ELSEVIER SCIENCE INC, 2022-01-01) Yildirim, Duzgun; Kandemirli, Sedat Giray; Sanli, Deniz Esin Tekcan; Akinci, Ozlem; Altundag, AytugRationale and Objective: To evaluate how COVID-19 anosmia imaging findings resembled and differed from postinfectious olfactory Material and Methods: A total of 31 patients presenting with persistent COVID-19 related OD and 97 patients with post-infectious OD were included. Olfactory bulb MRI, DTI and olfactory fMRI findings in both groups were retrospectively assessed. Results: All COVID-19 related OD cases were anosmic, 18.6\% of post-infectious OD patients were hyposmic and remaining 81.4\% were anosmic. Mean interval between onset of OD and imaging was 1.5 months for COVID-19 related OD and 6 months for post-infectious OD. Olfactory bulb volumes were significantly higher in COVID-19 related OD than post-infectious OD. Deformed bulb morphology and increased olfactory bulb signal intensity was seen in 58.1\% and 51.6\% with COVID-19 related OD
