8^(18)F-FDG PET/CT in diagnosis of skeletal metastases显示文摘This work is to evaluate correlated lesions in PET and CT images of patients suffering skeletal metastases so as to improve efficacy of 18F-FDG PET/CT in diagnosing bone metastases. PET and CT images of 25 patients with malignant tumor suspected bone metastases were reviewed independently by three experts. A region of interest was placed over each lesion, and the standardized uptake value (SUV) was calculated at the maximal single pixel value. The t and χ2 tests were used for statistical analysis. Of the 203 lesions detected on the PET and CT images, 189 were malignant and 14 were benign lesions. PET alone identified 159 malignant lesions and 6 benign lesions, CT alone identified 152 malignant lesions and 11 benign lesions. For PET, the diagnostic sensitivity, specificity and accuracy were 84.1%, 71.4% and 83.3%, respectively, while 80.4%, 71.4% and 83.3% for CT. No significant difference was found between PET and CT in detecting bone metastases (χ2=0.89, 0.19, 0.59, P>0.05). Statistical difference of positive ratio of PET was found between osteoblastic and osteolytic or mixed lesions (χ2=47.33, 7.93, both P<0.05). Of the 122 positive lesions on both CT and PET scan, the mean SUV was 5.76±3.41, 8.52±5.37 and 7.78±4.96 in osteoblastic lesions, osteolytic lesions and mixed lesions, respectively. Significant difference was found between osteoblast lesions and osteolytic lesions (t=2.28, P<0.05). PET images alone may leave out half of osteoblastic letions, but combined analysis of PET and CT images gives better diagnosis.LI Na LI Yarning YANG Chunming LI Xuena YIN Yafu ZHOU Jiumao 2009Nuclear Science and Techniques2009,20,6:0
9Coal Ash Slag Penetration Behavior on Cr_2O_3-Al_2O_3-ZrO_2 Bricks显示文摘The penetration behavior of different kinds of coal ash slags into chrome corundum bricks was studied by cup test. As a preliminary attempt,the oxides of Fe2O3 and MgO were added into coal ash to reduce the erosion of refractories. Different cup tests were carried out to study coal slag erosion to the refractories. FactSage was used to simulate the phase diagram of the main chemical compositions in coal ash and in the refractories. Both results agreed with each other. The results show that the elements in coal slag can penetrate into bricks and the penetration deepens with the duration increasing; it is difficult for Fe but easier for Ca and Si to penetrate into bricks; different kinds of melting coal ashes penetrate into refractories differently and the penetration depth of silicon and calcium can be significantly reduced by adding oxides into coal ash.TANG Lihua GAO Ling WANG Qiong CHEN Dongxia ZHOU Yarning WANG Wenmei WU Yongqiang ZHU Zibin 2010China's Refractories2010,19,4:0
