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.
ObjectiveTo investigate the methods and significances of the breast ultrasonographic breast imaging reporting and data system (BI-RADS) category 4 lesions divided into category 4a, 4b, and 4c, and to assess the risk of malig-nancy of lesions with BI-RADS category 4 in order to improve the accuracy of diagnosis. MethodsTwo hundred and eighty-eight breast lesions with BI-RADS category 4 confirmed by histopathology were collected. The ultrasonographic characteristics of benign and malignant lesions, containing the shape, aspect ration, margin, calcification, changes of the surrounding tissue, boundary, blood flow characteristics, internal echo, rear echo of the lesions, were comparatively anal-yzed, and the lesions with BI-RADS-US category 4 were divided into 4a, 4b, 4c according to these ultrasonographic charac-teristics and analyzed by statistics. ResultsThere were 192 malignant lesions and 96 benign lesions in the 288 breast lesions. There were statistical significances in the benign and malignant lesions with the shape, aspect ratio, margin, calci-fication, change of surrounding tissue, and boundary (P < 0.05), in other words, the proportion of these ultrasonographic characteristics were higher in the malignant lesions as compared with the benign lesions. But there were no significant differences of internal echo, rear echo, and blood flow characteristics between two lesions (P > 0.05). The positive predictive value of malignant tumor with BI-RADS category 4a, 4b, and 4c were 21.74%, 58.90%, and 91.78%, respectively, and there was significant difference (χ2=106.09, P=0.000). ConclusionsThe classification of breast lesions with BI-RADS category 4 is refined, it could more accurately assess the risk of benign and malignant breast masses. At the same time, it has an important clinical significance for diagnosis and treatment of benign and malignant breast masses.
【摘要】 目的 总结胆囊壁隆起样病变超声及病理特点，以提高此类疾病的鉴别诊断水平。 方法 回顾性分析2008-2009年222例经手术和病理证实的胆囊隆起样病变患者的临床资料，对其超声特点及病理学结果进行分析。 结果 胆固醇沉积症（包括附壁型37例和息肉型138例）175例（78.8%），炎性息肉（增生性息肉）3例（1.4%），腺瘤14例（6.3%），有7例腺瘤伴非典性增生，腺肌增生症1例（0.5%），单纯胆囊炎29例（13.1%）。 结论 超声对胆囊隆起样病变的诊断敏感性极高，能清晰显示其大小、数目、回声情况、病变形态和边界情况及局部胆囊壁的变化，有无合并结石等，还可方便地行随访观察，了解其动态变化，是简便可靠的诊断方法。【Abstract】 Objective To Summarize the common sonographical and pathological characteristics of apophysis lesions of the gallbladder, so as to improve the level of diagnosis and differential diagnosis. Methods Sonographical appearance and pathological characteristics of 222 patients from 2008 to 2009 with apophysis lesions of the gallbladder which were confirmed by pathologic diagnosis and operation were reviewed retrospectively. Results One hundred and seventy-five (78.8%) of the patients had gallbladder cholesterol lipoidosis and 138 (62.2%) of them had gallbladder cholesterol polyps;3 patients (1.4%) had gallbladder inflammatory polyp;14 patients (6.3%) had gallbladder adenomatoid polyps and 7 of them were accompanied with dyplasis and atypical hyperplasia; 1 (0.5%) patients (0.5%) had cholecystic adenomyosis. Tenty-nine patients (13.1%) had cholecystitis only. Conclusion Ultrasonography is quilt sensitive to this disease and can disply the size, number, echo, shape of the lesions and can show that if complicate with cholecystolithiasis.Ultrasonography is also accomplished in follow-up and can be one of the most dependable examination methods.
【摘要】 目的 通过对早期妊娠卵黄囊的观察，探讨其在早孕超声诊断中的临床价值。 方法 2008年5月-2009年1月应用阴道超声诊断仪观察536例早孕患者卵黄囊的形态、大小及卵黄囊的数目，根据结果分为卵黄囊正常及异常组，比较卵黄囊的增长情况与妊娠预后的关系。 结果 504例正常组中，501例正常妊娠结局的卵黄囊大小从孕5~11周持续增长，此后逐渐缩小，孕12周后消失；另3例为宫外孕而中止妊娠。卵黄囊异常组32例。正常组和异常组的卵黄囊大小及形态有统计学意义（Plt;0.05）。 结论 卵黄囊超声影像学改变可作为诊断早孕及预测妊娠发展和转归的可靠手段。【Abstract】 Objective To evaluate the clinical value of yolk sac in the diagnosis of early pregnancy by observing the change of yolk sac. Methods The yolk sacs in 536 pregnant women were measured by ultrasonogaphy from May 2008 to January 2009, and the correlation of the growth condition of the normal or abnormal yolk sac with pregnancy outcome were observed. Results In the normal group (504 patients), the yolk sac size of 501 patients continued to grow from five to 11 weeks of pregnancy, then gradually reduced and disappeared after 12 weeks of pregnancy. The other three patients terminated pregnancy because of ectopic pregnancy. Thirty-two cases of abnormal yolk sac were found. The results showed the size and shape of yolk sacs were significantly different between normal and abnormal groups (Plt;0.05). Conclusion The change of yolk sacs by ultrasonography during early pregnancy can be used as a good measure to diagnosis early pregnancy and predict the development and prognosis of pregnancy.
ObjectiveTo evaluate the value of preoperative risk assessment of papillary thyroid carcinoma with ultrasound for clinic diagnosis and treatment.MethodsThe data of 400 patients with papillary thyroid carcinoma received operative treatment in 2017 were retrospectively analyzed. Recorded and analyzed the ultrasonic risk assessment and postoperative grading of clinic risk assessment, to evaluate coherence and correlation between them.ResultsThere were 400 lesions with an average size of (12.8±8.5) mm. Among 400 lesions, diameter of 214 lesions less than 10 mm, diameter of 178 lesions were between 10 mm and 40 mm, and diameter of 8 lesions were larger than 40 mm. A total of 242 cases had lymph node metastasis and 309 cases had capsule invasion. Clinical and ultrasoud risk assessment was performed on 400 lesions. There were 224 lesions with low risk of clinical risk stratification vs. 111 lesions with low ultrasonic risk, 148 lesions with intermediate risk of clinical risk stratification vs. 270 lesions with intermediate ultrasonic risk, and 28 lesions with high risk of clinical risk stratification vs. 19 lesions with high ultrasonic risk. The consistency of postoperative recurrence risk stratification and preoperative ultrasound recurrence risk stratification was moderate (κ=0.414, P<0.01). In addition, the consistency between ultrasound examination and clinical lymph node metastasis was poor (κ=0.291, P<0.05), and the consistency of invasion of the capsule was moderate (κ=0.402, P<0.05).ConclusionPre- operative evaluation of recurrence risk grading before thyroid ultrasound, focusing on individualized preoperative assessment, the assessment is more detailed and detailed, and is helpful for follow-up treatment and early screening for recurrence risk.
