objective:to explore the clinical value of digital mammography on diagnosis of small breast cancer.methods:we retrospectively analyzed the representation of molybdenum target x-ray in 40 patients with small breast cancer diagnosed by biopsy.result:the molybdenum target x-ray showed nodosity tumor in 17 cases,calcification in 13 cases,density in 8 cases,focal grand architectural distortion in 6 case,single dilated in 3 cases and blood vessel line thickening in 6 case.conclusions:digital mammography is the most important means in the diagnosis of small breast cancer,which can distinguish between different kinds of breast density of different tissues and find small breast lump.the mammography has a high sensitivity in the diagnosis of small breast cancer.

目的：提高对小乳癌影像学的认识。方法：回顾性分析40例经病理证实的小乳癌患者的x线片。结果：x线表现为肿块17例，钙化13例，致密影8例，局部结构紊乱6例，单支导管扩张3例，血管影增多、增粗6例。结论：影像学是小乳癌诊断的最主要手段，能区别乳房各种不同组织的不同密度，能发现较小的乳腺肿块，对于乳腺癌的诊断，乳腺x线钼靶摄片具有较高的灵敏度。

Since the etiologic diagnoses of hepatitis A, B, C, D and E were established, there are still a part of patients with hepatitis in which the pathogenic causes can not be identified. After a lot of epidemiological and laboratory investigations, it was speculated that other parenterally transmissible pathogens causing human hepatitis existed.

自从建立起甲、乙、丙、丁、戊5种肝炎病毒的病原学诊断之后，仍有少部分肝炎患者的病因得不到明确，因此不少学者试图探索是否还有新型肝炎病毒的存在，并进行了大量的流行病学和实验诊断的研究，认为的确存在可经肠道外传播并引起人类肝炎的致病因子。1995年Simons等成功地克隆出2株黄病毒RNA序列，称之为GBV-A、GBV-B。

MethodsThe MRI appearances of 17 children with cerebral sparganosis proven by pathology or serological test were retrospectively studied. The diagnostic accuracy rate of cerebral sparganosis was compared before and after knowing the imaging features of this disease.ResultsEnhanced MRI was performed in 12 cases, and all of them demonstrated abnormal enhancement.

Results Computer-assisted detection is useful to distinguish the malignant from the tumors. The sensitivity and specificity for mass by CAD system were 79.82%、55.20%. the character of mass, such as breast parenchymal density, mass shape, mass margins, mass density, spiculated, have especial affect on the CAD system, which is very similar to the distinguish malignant and benign from the tumors .

肿块密度、毛刺征、肿块形态、肿块边缘以及乳腺的腺体类型等这些影像学特征对CAD的诊断能力均有显著影响，P值均小于0.0001，而且其影响作用强度与肿块影像学征象对单纯肿块性病变的良恶性的诊断上有较好的相似性。

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。
