RESUMO

Objective To evaluate the efficacy of the combination of gynecologic imaging reporting and data system (GI-RADS) uhrasonographic stratification and 3D contrast-enhanced ultrasonography (3D-CEUS) in identifying malignant lesions from benign ovarian masses.Methods Both of 2D ultrasound (2D-US) and 3D-CEUS were performed on 102 patients with ovarian masses.The perfusion characteristics of ovarian masses were observed with 3D-CEUS,and the 2D-US features of ovarian masses were analyzed based on GI-RADS.Simple and multiple Logistic regression analysis were used to investigate whether the independent risk predictors in differential diagnosis of benign and malignant ovarian could be confirmed.In addition,ROC curves were drawn.The diagnostic efficacy of GI-RADS combined with 3D-CEUS scoring system was evaluated and compared with that of only GI-RADS.Results Simple and multiple Logistic regression analysis confirmed that there were 8 independent predictors of malignant masses,including large papillary projections (≥7 mm),separated or wall thickness ≥3 mm,central blood flow,the proportion of solid part ≥50%,combination of ascites,high level enhancement,uneven distribution of contrast media in enhanced solid part and the vascular with characteristics as dense,tortuous and anfractuous.When using 4 points as the cut-off,the area under the curve (AUC) of GI-RADS combined with 3D-CEUS scoring system in identifying malignant ovarian masses was 0.969,higher than that of only GI-RADS (0.839;Z=1.64,P=0.029).Furthermore,the scoring system showed higher sensitivity,specificity,positive predictive value,negative predictive value and accuracy (all P<0.001).Conclusion The combination of GI-RADS with 3D-CEUS can be more effective to distinguish malignant lesions from benign ovarian masses.

RESUMO

Objective To evaluate the application value of three‐dimensional ultrasonography OmniView technology in diagnosis of fetal cleft lip/palate . Methods Three‐dimensional volume data was acquired from 100 normal singleton fetuses and 18 cleft lip/palate fetuses ,and was analysed by OmniView technology . Two‐dimensional ultrasonography and three‐dimensional OmniView technology were compared in the displaying rate of different planes of the lip and palate and the diagnosis accordance rate of cleft lip/palate.Results ①ThedisplayingrateofthelipandpalateofOmniViewtechnologywashigherthanthatof two‐dimensional ultrasonography ( the displaying rates were 64% -88% and 30% -65% ,respectively , P 0 .05) . Conclusions Three‐dimentional ultrasonography OmniView technology can improve the displaying rate of the hard and soft palate .The application of this technology in the fetuses who has a high risk of cleft palate may be beneficial to the diagnosis of cleft palate .

RESUMO

Objective: To investigate rules and affect factors in virus hepatitis complicated with biliary system damage. Methods: To observe 158 patients with various clinical types of viral hepatitis, gallbladder filling degree of gallbladder wall thickness, the gallbladder bile in the gallbladder situation, through sound situation by ultrasound, and the patients with intrahepatic, extrahepatic bile duct wall thickness were measured, the clarity of cavity were observed. Results:The 158 cases of patients with biliary ultrasonic testing results showed the gallbladder wall thickening, rough bilateral syndrome, sound transparent difference, stones, gallbladder enlargement or smaller, like solid. Severe hepatitis, biliary system in patients and liver cirrhosis was significantly higher than that of the abnormal in patients with acute hepatitis and chronic hepatitis (x2=17.96, x2=16.27; P<0.05). Conclusion: Viral hepatitis complicated with biliary system damage is related to clinical type, course of disease, liver function damage. Observe the change of ultrasonic dynamic biliary system, liver function testing timely, and provide the basis for guiding clinical treatment, to judge the severity and chronicity of hepatitis prediction.
