Aim: Evaluation of the number and character of pathological findings of thethyroid gland during PET/MRI examinations performed for an indication otherthan thyroid diseases.

Methods: We evaluated a cohort of 88 consecutive patients (17-83 years, men 37,women 51) who underwent PET/MRI of the whole body or just the neck and chestin the period October 2019 - March 2020 with the local guidelines in theUniversity Hospital Brno and in which any pathological finding was describedin the thyroid gland. Findings were divided into five groups. Furthermore, itwas evaluated whether the patients in the given groups are being monitored andwhether the findings are stationary or in partially regression.

Results: 88 patients in the study is 15% of all performed examinations (579).Number of patients in groups: morphologically visible lesion without activity35, activity in the thyroid gland without a morphological correlate 19, non-specific findings 15,morphologically visible lesion with activity 13, morphologically visiblelesion without activity with another area of higher activity in the thyroidgland 6. The highest number of monitored patients was in the group lesionwithout activity - 8, the smallest in the non-specific findings group - 2.Stationary finding or partial regression is most represented in the group oflesion without activity - 18, least in the group of non-specific findings - 3.

Conclusion: Various abnormalities can be found during a PET/MRI examination inthe thyroid gland, lesions with higher metabolic activity deserve greaterattention.
