Effects of hypothyroidism on serotonin 1A receptors in the rat brain.
Lee JH, Lee M, Park JA, Ryu YH, Lee KC, Kim KM, Choi JY. Lee JH, et al. Among authors: ryu yh. Psychopharmacology (Berl). 2018 Mar;235(3):729-736. doi: 10.1007/s00213-017-4799-y. Epub 2017 Dec 5. Psychopharmacology (Berl). 2018. PMID: 29209734
After hypothyroidism was confirmed by thyroid function tests, serotonin positron emission tomography (PET) was performed for 120 min. All PET data were spatially normalized to T2-weighted magnetic resonance imaging templates; then, time-activity curves of the hippocampus, …

Optimal timing of [¹⁸F]Mefway PET for imaging the serotonin 1A receptor in healthy male subjects.
Lee JH, Ryu YH, Lyoo CH, Choi SH, Kim JJ, Choi JY. Lee JH, et al. Among authors: ryu yh. Appl Radiat Isot. 2016 Jan;107:127-132. doi: 10.1016/j.apradiso.2015.10.004. Epub 2015 Oct 9. Appl Radiat Isot. 2016. PMID: 26492323
To determine the optimal acquisition time of [(18)F]Mefway PET, we examined the regional specific-to-nonspecific binding ratios and evaluated the relationship between distribution volume ratios (DVRs) and standardized uptake value ratios (SUVRs) in various time windows. The speci …
