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 探讨不同回声类型超声造影剂在胃肠疾病诊断中的价值。 方法 采用“胃窗声学造影剂”充盈检查法，用凸阵3.5 MHz探头，对2009年3-8月366名受检者行经腹壁超声检查。受检者随机分为两组：饮水者为A组，饮有回声造影剂者为B组。 结果 选择性地应用合适的造影剂，能有效地提高对胃肠疾病的超声诊断水平。【Abstract】 Objective To evaluate the application of contrast agents with different echogenic in the diseases of stomach and intestine. Methods Totally, 366 patients were included in the study from March to August 2009. Patients were randomly divided into two groups： group A (oral acoustic contrast agent) and group B (water). Contrast-enhanced Doppler sonography was performed with 3.5 MHz abdomen probe. Results Contrast agent with anechoic was good for showing iso-echoic and hyperechoic tissue.Hyperechoic contrast agent was better for showing hypoechoic changes according to its long sitting-time in stomach. Conclusion Contrast enhanced ultrasound has practical value in diagnosis of the diseases of stomach and intestine.
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.

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 evaluate the value of high-frequency color Doppler ultrasonography in the diagnosis of femoral hernia. MethodsThe ultrasonographic features of 39 femoral hernias in 37 patients treated between March 2008 and October 2013 were retrospectively analyzed, and the results were confirmed by surgery. ResultsThirty-nine femoral hernias were diagnosed by surgery, including 19 in the right side, 16 in the left side, and 2 with double-side hernias. Thirty-seven femoral hernias were diagnosed with ultrasonography. Two femoral hernias were misdiagnosed as lipoma in one, and as enlarged lymph nodes in one, respectively. Ultrasound diagnosis accurate rate was 94.9% (37/39). Hernia content could be seen through surgery in 28 cases, and the ultrasound accurate rate in assessing the hernia content was 85.7% (24/28). ConclusionUltrasonography is the first choice for improving the diagnosis efficacy of femoral hernia.
