Results Compared with conventional ultrasound,sonoCT could suppress the reverberation artifacts in bile duct and gallbladder obviously.Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.Thus,sonoCT raises the reliability of biliary tract tumors diagnosed by ultrasound.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

The method consists of tree steps: enhancement, contour segmentation, and feature selection. In this study, our method is able to enhance the signals from masses and extract the useful contour feature from the segmented regions. The ruler method of fractal dimension computed for each case was used to form a contour feature. These feature measures can be input to a classifier based on sorting. The experimental results show that our scheme can provide useful contour extraction for spiculation structures in mammographic images.

我们的研究目的是在乳房的X光影像中选取肿瘤怀疑的区域，分成三步骤，影像前处理、轮廓分割、特徵选取，找出具有星状物轮廓的肿瘤，我们的方法首先强化肿瘤组织，接著有效分割出肿瘤的轮廓，最后利用规则式的碎形维度计算其轮廓特徵值，接著排序分出肿瘤轮廓类别，实验结果证明我们的方法可有效侦测出星状物肿瘤轮廓及其特徵。

Abstract］ Objective To evaluate the distinctive clinical value of magnetic resonance urographyMRU）in the diagnosis of primary ureteral carcinoma.Methods To compare the accuracy of diagnosis of MRU with ultrasonography,urography,retrograde ureteropyelography and CT,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had MRU examinations.The original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、CT(19例）的确诊率相比较。

Abstract］ objective to evaluate the distinctive clinical value of magnetic resonance urographymru）in the diagnosis of primary ureteral carcinoma.methods to compare the accuracy of diagnosis of mru with ultrasonography,urography,retrograde ureteropyelography and ct,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had mru examinations.the original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.results mru could clearly show the obstructive location of ureter.with regard to the ureteral carcinoma,accuracy of the location diagnosis was 100%.mru was superior to ulstrasonography,kub+ivp,ureteropyelography and ct we used to apply.conclusion comparing with other diagnostic imaging facilities,it has an important value in highly efficient,accurate location,safe,noninvasive and so on with mru,which can be used to show the features of primary ureteral carcinoma and has a wider scope of clinical application.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值。方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、ct(19例）的确诊率相比较。结果 mru能清晰显示输尿管的梗阻部位，定位诊断准确率为100%，梗阻病因确诊率高于b超、泌尿系造影、逆行造影和ct检查。结论与其他影像诊断方法相比较，磁共振水成像在显示原发性输尿管肿瘤特征方面具有效率高、定位准确和安全无创等重要价值，而且有更广泛的临床应用范围。

Objective: To valuate the role of multi-slice CT perfusion imaging in the diagnosis of cerebral neoplasms.

目的：探讨多层螺旋CT(multislice spiral CT， MSCT)脑肿瘤灌注成像方法及其对脑肿瘤的诊断价值。

In conclusion, our research has indicated that amine oximes or other hypoxia imaging agents might not be structure-specific pharmaceuticals, and lipophilicity seemed to be an important factor in design for hypoxia agents.

由于〓Tc〓-〓在胃肠道等脏器分布较多，难以检测腹腔肿瘤，但可广泛适用于其它部位实体瘤的诊断。而上述三者更集中于肝、肾，可能适用于某些胃肠道肿瘤和妇科肿瘤的乏氧显像。
