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。

CT perfusion images can visually show different traits of Hemodynamics of hepatic Benign and Malign pathology; No matter what background, various parameters of hepatic tissue around malign lesions had significant difference with far-end liver tissue, while various parameters of hepatic tissue around benign lesions had no significant difference with far-end liver tissue; Allopatric efficiency of hepatic Malign pathology distinctly went up with hepatocirrhosis background;Various parameters of hepatic Benign and Malign pathology had no significant difference and differential significance were no significant.

灌注参数图像能直观显示肝脏良、恶性占位性病变血流动力学的不同特点；无论在何种背景下，恶性病变灶周组织与远端肝组织各同种参数间有显著差异，而良性病变灶周组织与远端肝组织各同种参数间无显著差异，以上特点可以鉴别肝脏占位性病变的良、恶性；肝硬化背景下，恶性病变的发生率明显增高；正常肝组织背景下，良、恶性占位病变组织灌注参数间无显著差异，鉴别诊断意义不大。

The mean ADC value of lymphomatous, metastatic and benign lymph nodes was (0.874±0.17)×10~(-3)mm~2/s,(0.98±0.09)×10~(-3)mm~2/s and (1.20±0.10)×10~(-3)mm~2/s. There was statistically different between benign lymph nodes and other groups (P=0.00). When an ADC value of 1.085×10~(-3)mm~2/s was used as a threshold value for differentiating malignant from benign lymph nodes, the best results were obtained with an sensitivity of 87.8% and specificity of 91.3%. 16 of 18 cases (88.9%) were accurately staged in accordance with clinical staging. For 24 patients after chemotheraphy or radiotheraphy, 4 cases were complete remission and WB-DWI was negative. WB-DWI was positive in 14 of 17 cases with recurrent or remnant tumor. For 3 patients with suspected partial remission, WB-DWI indicated necrosis in 2 cases and inactive in 1 case. Repeated WB-DWI examination was performed in 13 cases, tumors were eradicated in 6 cases, improved in 4, expanded in 2. A new colon carcinoma besides its primary lesion was found in 1 case. The results of WB-DWI were all concordant with other clinical tests.

以ADC值1.085×10~(-3)mm~2／s作为诊断恶性淋巴结病变的临界值，敏感性及特异性分别为87.8％和91.3％。88.9％(16／18)患者WB-DWI检查后分期与临床分期一致。24例淋巴瘤患者放化疗后行WB-DWI检查，4例临床疗效为完全缓解，WB-DWI检查均为阴性，17例临床确认有肿瘤复发及明显残留，WB-DWI显示为阳性的14例，另外3例常规影像评价为部分缓解的患者，WB-DWI检查提示2例病灶以坏死液化为主，1例病灶无明显活性。13例淋巴瘤患者行多次WB-DWI检查，发现6例治疗后病灶消失，4例缓解，1例原发病灶缓解，新出现结肠癌，2例淋巴瘤进展，皆与临床相符。

benign：良性的

守势现实主义则不认为如此,主张国际政治的结构事实上是良性的(benign),不必然造成冲突,但国家却认知错误,误以为结构是恶性的,造成许多战争的发生. 所以是国家搞错了,而不是国际结构本身的问题,国际结构所隐含的侵略诱因其实不多.

benign：良性

benign：性的

他在>中指出," 国际结构经常是良性的( benign) , 只会引发很少的战争. 但被认识到的力量结构往往是恶性的, 可以用来解释很多的战争. "[25](P6) 不过, 需要指出的是, 埃弗拉并不将战争起因完全归咎于认识错误.
