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。

Malignant melanoma can occur from skin, or any internal organs, among which skin melanoma is more frequently seen, especially in the skin of legs, cunnus, and crissum. However they have been rarely reported. Malignant melanomas of the internal organs can be easily diagnosed with its specitic MRI features, while the non-melanin contained melanoma which has no imageological specific feature are more difficult to be diagnosed. Because CT examination has no specific feature, MRI should be the first choice, for the suspect patient of malignant melanoma.

恶性黑色素瘤多发生于皮肤、内脏各种组织器官，其中皮肤恶性黑色素瘤多见，以下肢、外阴、肛周最多，鲜有影像报道；发生于内脏的恶性黑色素瘤多因具备特征性的MRI信号得以诊断，而不含黑色素的恶性黑色素瘤影像表现无特征性，诊断困难；CT检查不具备特征性，对于怀疑恶性黑色素瘤的患者，应首选MRI检查。

There is not a significant difference in these groups by one-way analysis of variance. 2 Among 51 cases with lung cancer, 7 specimens showed malignant cells in bronchial lavages, including 4 cases in central lung cancer and 3 cases in peripheral lung cancer. Concordant results were observed in 20 cases. 6 specimens showed malignant cells on cytological analysis, and NMSP was positive in at least one gene tested. 14 samples did not show malignant cells on cytological analysis, and the NMSP results were correspondingly negative. The results of cytology and NMSP were discordant in 31 samples. 30 samples were cytologically negative, but NMSP positive in one or more genes. In addition, there was one case that the cytology was positive for malignant cells, but the NMSP was negative in all of the three gene tested.
