摘要:目的: 探讨二维及彩色多普勒超声对妊娠合并卵巢扭转的诊断价值。 方法 :对11例经手术及病理证实的妊娠合并单纯卵巢扭转,进行二维及彩色多普勒和能量多普勒超声图像分析。 结果 :11例患侧卵巢在二维图像中均有不同程度的肿大,超声压痛征均呈阳性反应;其中7例有明显的位置改变,5例有不同程度的盆腔积液;彩色多普勒和能量多普勒显示患侧卵巢内部均无明显血流信号。 结论 :妊娠期卵巢扭转有典型超声图象特征,可为临床提供较可靠的诊断依据。Abstract: Objective: To evaluate the diagnostic value of two dimension ultrasound (2DUS), color Doppler flow imaging (CDFI) and power Doppler imaging (PDI) for ovarian torsion during the pregnant period.〖WTHZ〗Methods : Using the techniques of 2DUS, CDFI and PDI to analyze sonographic features of 11 ovarian torsion cases which were dominated by operation and pathology.〖WTHZ〗Results : The tumescent sick ovaries were detected in all case with ovaries torsion by 2DUS. The patient felt pain when their sick ovaries were pressed. The position of seven sick ovaries was changed. The pelvic effusion was detected in five cases. The blood flow signal was not demonstrated in all sick ovaries by CDFI and DPI.〖WTHZ〗Conclusion : The ultrasonic imaging characteristics are reliable to diagnose ovarian torsion during the pregnant period.
目的 分析彩色多普勒超声对肝硬化患者门静脉血流改变的评价作用。 方法 选择2010年1月－2011年4月收治的50例肝硬化患者作为观察组，其中代偿期患者27例，失代偿期患者23例；同时设置健康对照组50名，比较两组的门静脉内径（Dpv）、门静脉平均血流速度（Vpv）、门静脉血流量（Qpv）。 结果 观察组患者的Dpv增宽，Vpv减慢，Qpv减少，与对照组比较，差异均有统计学意义（P＜0.05）；且失代偿期患者的改变更为明显，与代偿期患者间差异有统计学意义（P＜0.05）。 结论 彩色多普勒超声检查门静脉血流改变可以对肝硬化患者进行初步确诊。
【摘要】 目的 探讨超声显像对肾上腺肿瘤的定位、定性诊断与鉴别诊断价值。 方法 对 2003年1月-2009年1月125例疑为肾上腺肿瘤患者进行超声及CT检查，并经手术与病理证实。超声显像诊断后经手术与病理证实为嗜铬细胞瘤48例，肾上腺皮质腺瘤41例，皮质腺癌11例，肾上腺转移癌 9例，髓样脂肪瘤8例，结节样增生2例，肾上腺结核4例，胰尾部肿瘤1例，肝脏肿瘤1例，肾上极肿瘤1例。 结果 肾上腺肿瘤的病理类型不同，声像图表现亦各不相同。超声显像定位诊断符合率为96.0%（120/125），定性诊断符合率为91.2% （114/125）。 结论 超声显像对肾上腺肿瘤的定位与定性诊断价值较大，可作为临床诊断的首选检查方法。【Abstract】 Objective To assess the value of ultrasonography in the diagnosis and differential diagnosis of tumors of adrenal gland. Methods From January 2003 to January 2009, 125 patients who were suspected to suffering from adrenal tumors underwent ultrasonography and CT examination. The results were then confirmed by surgery and pathology. There were 48 cases of pheochromocytoma, 41 adenoma, 11 adenocarcinoma, 9 metastatic tumor, 8 adrenal medullary lipoma, 2 nubblar hyperplasia, 4 tuberculosis of adrenal gland, 1 tumor of cauda pancreatic, 1 tumor of liver and 1 tumor of upper pole of kidney. Results The ultrasonographic features varied with different pathological types. The accuracy diagnosis of localizition and qualitation were 96.0% (120/125) and 91.2% (114/125) respectively. Conclusion Ultrasonography is useful in diagnosing tumors of adrenal gland, which may be used as the first choice for the disease.
Objective To investigate the characteristics of ultrasonogram of eyes with silicon oil tamponade. Methods Forty-seven patients (47 eyes) who had undergone the operation of silicon-oil removing were examined by A-(to determine the length of ocular axis) and B-scan before and after the operation respectively. The length of ocular axis and cubage of vitreous chamber were detected and the characteristics of the ultrasonograms were observed according to the default parameters of ultrasonograph. Results The results of A-scan showed that the preoperative axial length was 1.465 times of the postoperative one in the eyes without lens, and 1.284 times in eyes with lens; after modified the parameter according to the acoustic velocity, the preoperative axial length was (0.78±0.34) mm longer than the postoperative one in the eyes without lens, and (0.56±0.32) mm in eyes with lens. The results of A-scan showed that the cubage of vitreous chamber enlarged obviously in eyes with silicon oil tamponade, and the acoustic features included complete filling and partial filling according to the amount of silicon oil. Several arc echoes at the posterior segment of eye were detected in the silicon-oil-filling eyes with retinal detachment. Conclusion In the silicon-oil-filling eyes with lengthened ocular axis, the characteristics of B-scan images are affected by acoustic velocity through silicon oil, the amount of silicon oil capacity and the emulsification of silicon oil.
