Abstract
Objective: Radiologists use inverted image high resolution computed tomography (HRCT). Do inverted images help otologists and neurotologists identify temporal bone structures?
Methods: Two surveys compared identifying otosclerosis and the neural canals in regular versus inverted images. Survey 1 selected 7 regular/ inverted pairs of HRCT axial images from patients with successful stapedectomies. Seven regular/inverted pairs from non-pathologic HRCT temporal bones were normal counterparts to the otosclerosis bones. Thirty-five respondents reviewed these 28 images. Survey 2 selected 9 regular/ inverted pairs of non-pathological HRCT sections. Fourteen respondents identified the neural canals from the total of 18 images. Criterion-based scoring focused on those respondents with accuracy more than 72%.
Results: Twenty percent of respondents could diagnose otosclerosis, and 21% could identify the neural canals, with no significant difference between regular and inverted images.
Conclusion: Image orientation did not affect interpretation accuracy in those with the knowledge base to identify temporal bone structures.
