Comparação entre imagens adquiridas em apneia e respiração livre de lesões pulmonares por PET/CT ¹⁸F-FDG
Este trabalho teve como objetivo a análise de imagens PET/CT com dois protocolos: PET/CT com respiração livre e PET/CT no tórax inspirado em apneia, comparando-os para avaliação semiquantitativa e qualitativa da caracterização de lesões pulmonares hipercaptantes. Para isso, participaram do estudo 9 …

Invasive Physiologic Assessment of Myocardial Viability After Primary Angioplasty in Acute Myocardial Infarction: Comparison With FDG-PET Imaging
… mean transit time. 18F-fluorodeoxyglucose (FDG) PET was performed after primary PCI in 7 days to evaluate myocardial viability by regional percentage uptake of FDG in infarct-related segments. RESULTS: Among Doppler-derived parameters, regional FDG-uptake was associated with baseline average …

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 …

Correlation of Hepatic 18F-Fluorodeoxyglucose Uptake with Fatty Liver and Liver Function Tests
Liver demonstrates heterogenous FDG uptake pattern and sometimes shows abnormally increased uptake even though there is no malignant tissue. There was no previous study to correlate these various pattern of hepatic FDG uptake with benign liver disease. Therefore, we evaluated the significance of …

Imaging atherosclerotic plaque inflammation with [18F]- fluorodeoxyglucose positron emission tomography
… size and therefore angiographic appearance. FDG is a glucose analogue that is taken up by cells in proportion to their metabolic activity. In this work, the central hypothesis was that plaque inflammation could be visualised and quantified non-invasively using FDG-PET. Initially, THP-1 …
