Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.
材料与方法:搜集术前行乳腺MR检查并经穿刺或手术病理证实的236例乳腺病变,以对侧正常乳腺腺体作为正常对照,采用横轴位的平面回波-扩散加权成像序列,TR=8400ms,TE=93.8ms,层厚=4mm,激励次数=2:视野=30×30cm,矩阵=128×128,ASSET=2,b值=0和1000s/mm~2;参考动态增强图像准确定位,测量病变区和对侧正常乳腺腺体的ADC值,应用t检验比较良、恶性病变及正常腺体ADC值的差异,采用接收者工作特征曲线(receiver operating characteristic curve,ROC)确定良恶性病变的ADC界值;根据BI-RADS MRI将乳腺病变按照形态学表现分为肿块性病变和非肿块性病变两组,比较ADC值在肿块和非肿块性病变中定性诊断的效能。

First, from room temperature to 500oC, the shell structure is amorphous with crinkly and airtight character. The shell structure begins to change into γ-Al2O3 and α-Al2O3 at 900oC. The surface of shells shows nano-sized pores at 900oC from SEM and BET analyses. When heated to 1000oC and 1100oC, the shell forms stable α-Al2O3 structure with smooth surface. Cracks often occur at the triple grain junctions. The specific surface area and the total pore volume of the hollow spheres increase with the calcination temperature.
首先,将锻烧温度由室温提升至500℃时,球壳属非晶相皱褶状致密结构;在900℃时开始有γ-Al2O3相及些许的α-Al2O3相出现,由SEM及BET结果得知,900℃之球壳表面有许多奈米级孔洞出现;当加热至1000℃和1100℃时,球壳形成稳定相之Al2O3结构,壳层表面趋於平滑,且球壳在晶界处有微裂缝存在;由BET 结果得知,比表面积及总孔洞体积会随锻烧温度之增加,有增加之趋势。
