The Effect of Ultra-short Acting Insulin on F-18 FDG PET/CT Image Quality of Patients with Uncontrolled Diabetic Mellitus
혈당이 조절되지 않는 당뇨 환자에서 F-18 FDG PET/CT의 영상의 질은 좋지 않다. 본 연구에서는 당뇨 환자의 F-18 FDG PET에서 초속효성 인슐린의 효과와 임상적 유용성에 대해 알아보고자 하였다. 본 연구는 각종 암으로 진단 받은 당뇨 환자 중 F-18 FDG PET/CT를 시행한 105명(남/여: 68/37, 평균나이: 60±12세)을 대상으로 하였다. F-18 FDG 주사 60분 전 혈당이 190mg/dl 이상인 환자(n=53)에게 초속효성 인슐린(Humalog？？)을 정맥 주사하였다. 혈당이 189mg/dl …

골경화성 골전이를 동반한 유방암 환자에서 F-18 fluoride PET/CT의 유용성
… used to evaluated bone metastases and also F-18 FDG PET/CT seems to exhibit high specificity and accuracy to detect skeletal metastases. However there is the limitation of F-18 FDG PET in assessing sclerotic bone metastasis because the lesions can be undetectable. Recent studies showed that F-18 …

Evaluation of 18F FDG-PET/CT in Patients with Gastric Signet Ring Cell Carcinoma : Correlation with GLUT-1 Expression and Histologic Finding
… ring cell carcinoma (GSRC) is known to have low FDG uptake. The aim of the study was to investigate the relation between FDG uptake and glucose transporter-1 (GLUT-1) expression in GSRC patients. MATERIALS AND METHODS: Forty patients (28 men, mean age 54±12) with histologically confirmed GSRC who …
