Joon Young Choi 교수의 연구실은 정밀의학 기반의 임상 영상 진단과 예후 평가를 핵심으로 삼고 있습니다. 특히 18F-FDG PET/CT를 활용한 암 진단 정확도 향상, 이차 원발암 스크리닝, 종양의 예후 인자 분석(예: 림프절 수 및 종양 길이) 등에서 뚜렷한 기여를 하고 있습니다. 신경영상 분야에서는 피질발달이상성 병변의 정확한 영역 규명을 위해 PET와 MRI의 융합적 응용을 연구하고 있으며, 심폐소생술 후 병변 관리에서도 혈액순환 이상에 따른 이질적 저산소증의 진단 및 치료 전략을 제시하고 있습니다.

Focal thyroid lesions incidentally found on (18)F-FDG PET/CT have a high risk of thyroid malignancy. Image interpretation that includes (18)F-FDG uptake and the CT attenuation pattern, along with the SUV, significantly improves the accuracy of PET/CT for differentiating benign from malignant focal thyroid lesions.
FDG PET/CT at the time of the initial staging is useful for screening a second primary cancer with a high sensitivity. An additional diagnostic work-up is essential when abnormal findings, which are indicative of a second primary cancer, are obtained on PET/CT images to rule out the presence of either a second primary cancer or an unexpected metastasis.
In addition to the pathologic stage, (18)F-FDG PET provides noninvasively independent prognostic information using the number of positive lymph nodes and the tumor length on the PET image in preoperative esophageal squamous cell carcinoma. A revised TNM classification system for esophageal carcinoma may consider tumor length and the number of positive lymph nodes as important prognostic factors.
FDG-PET is more useful in delineating the cortical abnormality in patients with mild degrees of FCD. The extent of the lesion was larger or similar on FDG-PET compared with that of the MRI.
Veno-arterial extracorporeal membrane oxygenation (ECMO) through the femoral vein and artery may cause differential hypoxia, i.e., lower PaO2 in the upper body than in the lower body, because of normal cardiac output with severe impairment of pulmonary function. Hereby, we report the diagnosis and the treatment of differential hypoxia caused by veno-arterial ECMO. A 39-year-old man received cardiopulmonary resuscitation from a cardiac arrest due to acute myocardial infarction. Even after more th
The currently available literature suggests that the use of <sup>18</sup>F-FDG PET or PET/CT for evaluation of response to NAC provides significant predictive value for disease recurrence and survival in breast cancer patients and might allow risk stratification and guide rational management.
(18) F-FDG PET/CT is a useful imaging modality for differentiating malignant from benign PA lesions in patients with inconclusive low-attenuation filling defects on contrast-enhanced chest CT.
Taking a step forward from the IPI, attention is focused on the role of 18F-FDG PET/CT as a tool for guidance in risk stratification in patients with aggressive non-Hodgkin's lymphoma (NHL). Here, we analyzed the predictive value of various PET/CT parameters in patients with DLBCL. Particularly, we were interested in patients with an IPI score of 1, 2, or 3, whose prognosis are confusing. Between Jul 2008 and Feb 2010, a total of 100 patients (including 57 patients with an IPI score of 1-3) who
