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。

With respect to phonetics, Distinctive Features for the phonetic syncopation of spatial information are extracted based on Bertin's retinal variables. The importance of geographic reality, cognitive laws and geometric laws in the syncopation is pointed out following the thorough inspection of the physical characteristics of spatial information and a phonetic hierarchy of phoneme、 phoneme combination is proposed after the summarization of different methods of syncopation in Psychology, Pattern Recognition, Mathematic Morphology and Cartography, which provides linguistic interpretation for cartographic symbol design and understanding. With respect to the property that map symbol is represented as the combination of attribute and geometry in digital form of spatial information, suprasegmental phoneme as unit is proposed which deals with the high level phonetic units and their structure with the bend of curve and the simple area of complex area as primitive.
在语音结构方面,基于Bertin的视觉变量,提取了产生空间信息语音切分的区别特征;对空间信息的物理特征进行了详尽分析,指出了地理真实、认知规律和几何规律在语音切分中的重要作用;在总结心理学、模式识别、数学形态学和地图学等相关切分理论的基础上,提出了空间信息音位系统以及音位组合规律,为地图符号设计与理解提供了语言学解释;针对地图符号通常在空间信息中表现为属性和形态相结合的特点,提出在超音段音位层次上重点关注以线切分单元——弯曲和复杂面切分单元——弯曲构成的简单面为基本元素的语音高级层次及其结构。
