Incidental findings at MRI of the lumbar spine were common and associated with age and sex. Most were benign findings. An awareness of the prevalence of the incidental findings detected at MRI of the lumbar spine is helpful for diagnosing lesions not related to symptoms.

US-FNAB of thyroid nodules smaller than 5 mm in maximum diameter was less successful, and the sensitivity was lower than those of nodules larger than 5 mm. We considered, however, that the sampling adequacy and efficacy of US-FNAB of thyroid nodules less than 5 mm in maximum diameter was satisfactory in our series and should be similar in other centers with similar characteristics to ours.
