In Vivo Quantification of Cerebral Translocator Protein Binding in Humans Using 6-Chloro-2-(4'-123I-Iodophenyl)-3-(N,N-Diethyl)-Imidazo1,2-aPyridine-3-Acetamide SPECT
Conclusion: As demonstrated within a group of stroke and GBM patients, 123I-CLINDE SPECT can be used for quantitative assessment of TSPO expression in vivo. Because of the absence of a region devoid of TSPO, reference tissue models should be used with caution. The 2-tissue-compartment kinetic analysis of a 90-min dynamic scan with arterial blood sampling is recommended for the quantification of 123I-CLINDE binding with SPECT.

Clinical implications for Translocator Protein (TSPO) imaging using 123ICLINDE SPECT: A feasible approach
Conclusions The preliminary results imply that [123I]CLINDE-SPECT is a feasible approach for TSPO imaging in neurological disorders associated with microglial activation and/or increased TSPO expression. The development of methods that do not need arterial blood sampling for quantification of TSPO will be important to ease implementation in a daily clinical setting. Further clinical studies are needed to determine the precise role of TSPO imaging in predicting clinical outcome and treatment response.

All That Glitters Is not Gold: Peals and Pitfalls in I-131 Scans for Differentiated Thyroid Cancer
Conclusion: We review thyroid gland physiology and describe a systemic overview of potential false positive and false negative lack of uptake of radioiodine in the whole body along with illustrations and cases. By understanding the physiology and characteristics of radioiodine uptake and correlating with anatomical imaging, biochemical data, and clinical findings, physicians can be more confident in establishing proper management for patients with DTC using radioiodine whole body scans.

60 Years of Achievements by KSNM in Neuroimaging Research
AbstractNuclear medicine neuroimaging is able to show functional and molecular biologic abnormalities in various neuropsychiatric diseases. Therefore, it has played important roles in the clinical diagnosis and in research on the normal and pathological states of the brain. More than 400 outstanding studies have been conducted by Korean researchers over the past 60  years. In the 1990s, when multiheaded single-photon emission computed tomography (SPECT) scanners were first introduced in South Korea, stroke research using brain perfusion SPECT was conducted. With the spread of positron emission tomography (PET) scanners in...
