| 内容記述 | The purpose of this study was to compare the utility of a dual-head positron coincidence detection gamma camera(PCD) with that of dedicated positron emission tomogrphy(PET) in the imaging of various malignncies using 18F-fluorodeoxyglucose (FDG). 25patients with known or suspected malignancies at various sites underwent imaging with both methods, and diagnostic performance on a lesion basis was compared. Tumour lesions were analyzed visually and semi-quantitatively using the ratio of tumour-to-background counts(T/B ratio). FDG PCD and FDG PET visually detected 34 (72.3 ) lesions and 37 (78.7 ) lesions, respectively. The mean T/B ratio and standard deviation (SD) of FDG PCD was 3.5 3.3, significantly lower than that of FDG PET (8.4 7.1,p 0.001). When tumour lesions were less than 2.0cm in diameter,the sensitivity of FDG PCD was 37.5 ,significantly inferior to that of FDG PET (50.0 ,p 0.01). Sensitivity between FDG PCD and FDG PET in lesions of more than 2.0cm diameter showed no statistically significant difference. This study indicates that FDG imaging with a dual-head coincidence detection gamma camera can provide suitable diagnostic performance for lesions greater than2.0cm diameter, but performed significantly worse than dedicated PET for lesions smaller than this. | |||||
