Transvaginal Ultrasound Combined With Prediction Research In The Diagnosis Of Uterine Cavity Accounted For Elasticity Imaging Techniques To

Background and ObjectiveEndometrial cancer (Endometrial Carcinoma, EC) is one of three common cancer of the female reproductive system.In the European and American countries with high incidence,In our country in recent years the incidence rate increased significantly.Postmenopausal women with high-risk population.The disease occurs in the endometrium are epithelial malignancies.Mainly as irregular vaginal bleeding.In recent years, ultrasound elastography (Ultrasonic Elastography, UE) as a new diagnostic technologies evolving.The basis for organizing different hardness (closely related to its pathology constitutes), providing new diagnostic information diseased tissue.Breast, thyroid and other superficial organ disease diagnosis has also been widely used in the liver, heart and other aspects also have a series of studies, but in the uterine cavity of research is rare.Malignant uterine tissue stiffness increases.Combined with the use of transvaginal ultrasound elastography objective analysis of diseased tissue hardness, and then to express different color and disease-related data between benign and malignant. The purpose of this study include the following four:1. Describe the different characteristics of uterine myoma and endometrial cancer and other state normal uterus, endometrial polyps, submucous by two-dimensional ultrasound and elastography imaging.2. To investigate the blood flow under the condition of different types of endometrial cancer affects the elastic classification.3. Research elastography technique for uterine occupying lesions of diagnostic value.4. More flexible rates and strain rate ratio (Strain Ratio, SR) diagnostic accuracy of benign and malignant lesions of the uterine cavity.Objects and MethodsSelect January2013-2014January gynecology clinic patients in our hospital, transvaginal ultrasound and transvaginal ultrasound elastography examination.Normal intrauterine group of25patients, mean age (30±2.3) years of age.Occupying63cases of intrauterine average age (43±3.1) years of age.28benign lesions and malignant lesions35, were treated in our hospital and surgical pathology.Optional Hitachi HV-900color Doppler ultrasonography, frequency4-8MHZ vaginal ultrasound probe.Was seized by transvaginal ultrasound.After the discovery of lesions, image analysis features to achieve the desired two-dimensional image.Then enters the elastic imaging.Analysis of the characteristics of different elastic image intrauterine state.Determination of strain rate ratio.Finally, make elastic score (5points standard).Results1. Elastic image characteristics of different states of intrauterineNormal uterine cavity:the main green.Endometrial polyps:with green with small amounts of red and (or) blue.Submucous myoma:In green, visible green and blue, or blue, red.Endometrial cancer:Mainly in blue, there is little green, or blue. 2. Abundant blood flow signal in15patients with endometrial carcinoma,6cases with5points,7points in4cases,2cases of≤3. Blood flow signals are not rich in11patients with endometrial carcinoma,1cases with5points,7points in4cases,3cases of≤3. No blood flow signal type of endometrial carcinoma in9cases,1cases with5points,2points in4cases,6cases of≤3.3. When analyzing the nature of intrauterine lesions, the specificity of transvaginal ultrasound, sensitivity, respectively:59.0%,79.2%.The elastic score specificity, accuracy were:68.8%,80.6%. A combination of imaging specificity, accuracy were:86.7%,93.9%. Both were in conjunction with imaging contrast.The statistical results respectively (χ2=5.760, P<0.05. χ2=6.261, P<0.05), tip statistically significant difference.4. The ratio of the measured strain rate of benign and malignant lesions of the uterine optimal cutoff value of2.98.And the elastic strain rate ratio score diagnosis of intrauterine lesions of the receiver operating curve (ROC) area under the (Az), respectively:0.852and0.761, statistical results (χ2=4.663,P>0.05),tip difference was not statistically significant.Conclusions1. Ultrasound elastography as a transvaginal ultrasound good supplement for the diagnosis of disease provides more valuable information, provide strong evidence for a more intuitive nature of the diagnosis of intrauterine lesions.2. Blood flow distribution types of endometrial cancer will not affect the elasticity classification.3. Rated elastic strain rate ratio diagnosis of intrauterine lesions Nature is a new technique, the accuracy of the former is slightly lower than the latter, the difference was not statistically significant.
