About the Lab

Professor Gi Jeong Cheon's research lab specializes in molecular imaging and biomedical diagnostics, focusing on the development and application of advanced imaging techniques such as PET and SPECT to improve cancer diagnosis, prognosis, and treatment monitoring. The lab investigates neuroinflammation in chronic pain disorders like complex regional pain syndrome using novel radioligands, and explores exosome-based liquid biopsies for early disease detection. A key emphasis is on translating molecular imaging biomarkers into clinical practice for personalized oncology and neurological disorders.

Prediction Model of Chemotherapy Response in Osteosarcoma by <sup>18</sup>F-FDG PET and MRI

SJR Q1FWCI 7.6Journal of Nuclear MedicineOA

Response to neoadjuvant chemotherapy is a significant prognostic factor for osteosarcoma; however, this information can be determined only after surgical resection. If we could predict histologic response before surgery, it might be helpful for the planning of surgeries and tailoring of treatment. We evaluated the usefulness of <sup>18</sup>F-FDG PET for this purpose. <b>Methods:</b> A total of 70 consecutive patients with a high-grade osteosarcoma treated at our institute were prospectively enr

Complex regional pain syndrome (CRPS) is characterized by severe and chronic pain, but the pathophysiology of this disease are not clearly understood. The primary aim of our case-control study was to explore neuroinflammation in patients with CRPS using positron emission tomography (PET), with an 18-kDa translocator protein specific radioligand [C]-(R)-PK11195. [C]-(R)-PK11195 PET scans were acquired for 11 patients with CRPS (30-55 years) and 12 control subjects (30-52 years). Parametric image

SJR Q1FWCI 3.1NanomaterialsOA

Exosomes are attracting attention as new biomarkers for monitoring the diagnosis and prognosis of certain diseases. Colorimetric-based lateral-flow assays have been previously used to detect exosomes, but these have the disadvantage of a high limit of detection. Here, we introduce a new technique to improve exosome detection. In our approach, highly bright multi-quantum dots embedded in silica-encapsulated nanoparticles (M-QD-SNs), which have uniform size and are brighter than single quantum dot

Purpose Fibromyalgia (FM) and complex regional pain syndrome (CRPS) share many pathological mechanisms related to chronic pain and neuroinflammation, which may contribute to the multifactorial pathological mechanisms in both FM and CRPS. The aim of this study was to assess neuroinflammation in FM patients compared with that in patients with CRPS and healthy controls. Methods Neuroinflammation was measured as the distribution volume ratio (DVR) of [ 11 C]-(R)-PK11195 positron emission tomography

SJR Q2FWCI 1.7Clinical Nuclear Medicine

Anti-LGI1 encephalitis is a subgroup of autoimmune encephalitis, characterized by memory impairments, seizures, and behavioral problems. The diagnosis can be made by clinical manifestation with a help of serum autoantibody test. There was lack of imaging studies to evaluate and monitor the disease activity by anatomical and functional information. Here, we report serial F-FDG PET/CT findings in a patient with anti-LGI1 encephalitis. Intense F-FDG uptake was initially noted in bilateral limbic sy
