Abstract］ objective to investigate anus sphincter preserved surgical method and indication for low rectal cancer.methods 15 cases with low rectal cancer were operated with eversion and pull-through anus preserved colorectal anastomosis through anus.results no patients died of operation,no patients was with fistula and stricture of anastomosis,no defecation incontinence happened after postoperative 20 weeks,only one patient was with local recurrence.following up for 8 months to 5 years,5 cases were with distant metastasis,4 of these died,one of these had lived with liver metastasis for 3 years.conclusion the indication of anus preserved operation should be chosen according to clinical stage and biological characteristic of rectal malignancy; eversion and pull-through anus preserved colorectal anastomosis through anus is a better anus preserved operation for low rectal cancer.

目的 探讨低位直肠癌保留肛门括约肌功能的手术方法和手术适应证。方法对低位直肠癌经腹经肛门直结肠外翻拉出保留肛门吻合术15例。结果全组无手术死亡，未发生吻合口漏和吻合口狭窄，局部复发1例，20周左右恢复正常排便排气功能，无大便失禁病例。随访8个月～5年，5例为远处转移，死亡4例，其中1例肝转移3年仍生存。结论根据直肠癌的临床分期和肿瘤的生物学特性选择保肛手术适应证，经腹、肛门齿线上直肠癌根治性切除，行肛门直结肠外翻拉出吻合是低位直肠癌较好的保肛术式。

PartⅢDiagnostic strategy of Breast Lesion using combination of dynamic contrast-enhanced and diffusion-weighted imagingPurpose:To evaluate the diagnostic accuracy of a combination of dynamic contrast-enhanced MR imaging and diffusion-weighted MR imaging in characterization of breast lesion and to find the strongest discriminators between malignancy and benignancy.Materials and Methods:223 patients with 236 pathology-confirmed breast lesions were examined using EPI-DWI,FSE-T2WI,SE-T1WI,DCE-MR imaging were performed using VIBRANT sequence.

第三部分磁共振动态增强扫描结合扩散加权成像诊断乳腺癌的策略研究目的：分析乳腺良、恶性病变的形态学表现、血流动力学表现，结合ADC值，采用单变量和多变量分析，挖掘有意义的恶性MR征象，制定乳腺癌的诊断策略，探讨动态增强MR(dynamic contrast-enhanced MR imaging，DCE-MRI)结合DWI对乳腺病变的诊断和鉴别诊断价值。

MR images was analyzed include tumor shape,margin, internal enhancement characteristics,distribution,and time-signal intensity curves,maximam enhancement ratio,early enhancement ratio and so on.The ADCs of lesions were calculated on ADC maps.Univariate and multivariate analysis of MR imaging data were performed to find the strongest discriminators and the Logestic regression model was established to predict the probabilities for malignancy.

由放射科医生采用双盲法阅片，根据乳腺MR影像报告及数据系统(BI-RADS MRI)，将病变按照不同形态学表现分为肿块和非肿块性病变两组，分析形态学表现(形状、边缘、分布特征、内部增强特征)、血流动力学表现(时间-信号强度曲线类型、最大增强率、达峰时间、早期增强率)，并结合ADC值，应用SPSS15.0软件进行单变量及多变量分析，挖掘有意义恶性征象，建立回归模型，计算其敏感性、特异性、准确性、阳性预测值和阴性预测值。
