阴道彩超检测黄体形态及其血流鉴别宫内外早早孕的研究

目的 :探讨阴道彩超 (TVCD)检测黄体形态及其血流鉴别宫内外早早孕的可行性。方法 :对 96例处于早早孕阶段的黄体形态及其血流进行 TVCD检测 ,检测结果与最终妊娠结果进行对照分析。结果 :宫内早早孕组黄体形态常较饱满 ,壁常较厚呈“双环征”,其血流阻力指数 (RI)常 <0 .5 ;宫外早早孕或宫内早孕流产组黄体形态常欠饱满 ,壁常较薄 ,其血流 RI>0 .5。结论 :TVCD检测黄体形态及其血流 ,并结合宫内或附件区的声像特点 。

PRELIMINARY APPLICATION OF COLOR DOPPLER FLOW IMAGING IN THE LOCALIZATION OF PARATHYROID ADENOMAS

From December 1991 to April 1993, we performed color Doppler flow imaging (CDFI) in 11 patients with parathyroid adenoma, and all cases were confirmed by operation and pathology. In all the parathyroid adenomas,vessels were clearly revealed at the periphery of the upper pole and/or anterior periphery, where arterial signals were elicited. These arteries had branches into the adenomas and originated from inferior thyroid arteries on the same side in most cases. The internal flow signals were increased markedly as compared to normal thyroid, and high-velocity arterial signals were detected. Because of the thyroid' s rich blood supply and landmark peripheral vessels, CDFI can distinguish parathyroid foci from thyroid nodules, lymph nodes, and normal tissues and provide a sound basis for the diagnosis of small parathyroid foci.

彩色多普勒超声对胆囊疾病的诊断价值探究

目的:探究彩色多普勒超声在胆囊疾病中的诊断价值。方法:选取2014年4月至2017年4月笔者所在医院治疗胆囊疾病的80例患者,按照病理结果将患者分为两组,即患有胆囊癌的40例研究组患者与患有胆囊炎的40例对照组患者。为两组患者采用彩色多普勒超声进行检查并对比其检查结果。结果:两组患者均存在胆囊壁增厚表现,在胆囊壁厚度上两组患者较为相近,差异无统计学意义(P>0.05)。对照组黏膜线回声完整,有低回声结节存在于胆囊壁内,囊内有胆泥回声,彩超可见呈点状分布的血流信号;而研究组的黏膜线回声并不完整,部分患者胆囊中含有泥沙样的结石,于彩色多普勒超声图像中出现粗大的穿支血流信号。在血流分布上,两组有明显不同,差异有统计学意义(P<0.05)。结论:彩色多普勒超声从血流信号、回声完整度等指标有效鉴别胆囊炎与胆囊癌,是胆囊癌筛查的手段。
