简介:摘要本文报道了经手术、病理证实的28例(36个)仅含腺体的副乳腺,并根据不同受检时期将本组病理分成四组,阐明了哺乳期、妊娠期、月经期、平常受检期副乳腺的各自声像图特点及与皮肤肿块、脂肪瘤、纤维腺瘤、淋巴结相鉴别的要点。
简介:摘要副乳腺是一种先天性发育异常,临床上并不少见,然而目前副乳腺的影像学诊断报道并不多见。本文报道了经手术病理证实的40例副乳腺超声图像特点,及副乳腺组织与腋窝淋巴结和脂肪瘤在超声图像鉴别诊断要点,阐明在怀疑乳腺癌病例,正确区分副乳腺和肿大淋巴结可避免不必要的外科手术。

简介:摘要目的本文主要综合分析副鼻窦低剂量CT扫描的最佳条件。材料与方法选取我院2012年-2013年之间的患者共计60例,对全部患者的副鼻窦均统一采用冠状位螺旋CT扫描,扫描条件分别为120KV、250mA,200mA,100mA,50mA,25mA,5mm层厚,5mm间隔,扫描时间为1s.最终将扫描图像由专业CT室医师以及技师对其影像的结果的结果进行观察分析,并作出最终评分,分析在保证图像的质量的基础上,均采用低剂量最佳低扫描条件。结果通过低剂量CT扫描方式,专业CT室技师能够清晰的判断患者病变部位,并可以明确作出诊断。结论低剂量扫描在保证副鼻窦病变的影像质量前提条件下,保护管球的同时,也大大降低了患者的照射剂量,达到双结合的优势。
