Abstract

Objective: This study aimed to evaluate the incidence rates,
reporting rates, and the best imaging plane and sequence for incidental
findings in patients undergoing spinal and brain magnetic resonance (MR)
imaging.

Methods: Three experienced radiologists retrospectively re-evaluated
the MR images of 1056 consecutive patients.

Results: The incidence rates for extraspinal incidental
findings for the images of the lumbar, thoracic, and cervical spine, and extra-neuronal
incidental findings on MR images of the brain were 35.47%, 32.25%, 29.16%, and
54.35%; respectively, with reporting rates of incidental findings for these
examinations of 31.47%, 8.33%, 29.50%, and 59.62%; respectively. For all
examination types, the T2-weighted sequence and the axial plain were the best
to reveal the incidental findings of MR examinations, other than that of the
cervical spine.

Conclusions: Incidental findings, which are commonly detected
during routine spinal and brain MR evaluations, are occasionally omitted from
formal radiological reports in daily practice. We strongly recommend checking
the T2-weighted axial plane for MR imaging of the lumbar, thoracic spine and
brain and taking a second look at the T2-weighted sagittal plane MR images of
the cervical spine during radiological evaluations.
