Value of ultrasound elastography in diagnosis of cervical tuberculous lymphadenopathy / 第二军医大学学报

Objective To analyze and compare the ultrasound elastography (UE) features of various types of cervical tuberculous lymphadenopathy (CTL), and to investigate the value and limitation of UE in diagnosis of CTL. Methods A total of 70 CTL patients confirmed by pathology or diagnostic treatment who were admitted to Shanghai Pulmonary Hospital affiliated to Tongji University from Jul. 2017 to Mar. 2018 were enrolled, and the images of conventional ultrasound and UE of the largest lymph nodes in each patient were retrospectively analyzed. According to the conventional ultrasound classification criteria of tuberculous lymphadenopathy, the lesions were divided into acute inflammatory type (type), caseous necrotic type (typeⅡ), cold abscess type (type III) and healing calcification type (type ). The elasticity score and strain ratio of various types of CTL lesions were summarized and compared. Results There were 24 (34.29%) typeCTL lesions, 28 (40.00%) typeⅡ, 12 (17.14%) type III, and 6 (8.57%) type . The hardness of CTL lesions of typeand typeⅡ was high, with the elastic score being 3-4 (47/52, 90.38%) and the strain ratio being 3-5; the hardness of type III was the lowest, with the elastic score being 1-2 (10/12, 83.33%) and the strain ratio2; the hardness of type was the highest, with the elastic score being 4-5 (6/6, 100.00%) and the strain ratio5. There were significant differences in elastic score and strain ratio among the four type CTL lesions (H＝30.756, F＝23.177; both P0.001). Pairwise comparison showed that except for the differences between typeand typeⅡ lesions, there were significant differences in elastic scores and strain ratios between the four type CTL lesions (P0.05). Conclusion The value of UE in the diagnosis of CTL is limited. It may play some roles in determining whether there is an obvious granuloma formation in typelesions and the tension of type III lesions.

Current situation and thinking of ultrasonic diagnosis of tuberculosis / 第二军医大学学报

China has the third largest tuberculosis burden in the world, with a heavy anti-tuberculosis task. In recent years, ultrasound imaging technology has been widely used in the diagnosis of pulmonary and extrapulmonary tuberculosis. Because of its simplicity, convenience, and diagnostic function for multiple organs, ultrasound has gradually become an effective auxiliary diagnostic method for tuberculosis. In this paper, we reviewed the application status, problems and prospects of ultrasonic techniques in tuberculosis, hoping to provide new methods for the diagnosis of tuberculosis.

ROC Analysis of the Diagnosis of Uterine Myoma Degeneration was Diagnosed by the Real-time Ultrasound Elastic Imaging Score / 医学研究杂志

Objective Using real-time ultrasound elastic imaging technique to score patients with uterine fibroids,and The ROC analysis of the diagnosis of uterine myoma degeneration was studied and analyzed,so as to explore a technique of real-time ultrasound elasticity imaging diagnostic value for denatured uterine fibroids.Methods Selected from April 2014 to June 2016 hospitalized patients with uterine fibroids treated during the period of 85 cases (118 lesions),Using real-time ultrasonic elastic imaging technique to score,postoperative pathological examination was performed to confirm whether the uterine myoma degeneration occurs,the pathological results were compared with Elastic imaging score.Finally,the ROC curve was drawn to analyze its diagnostic value.Results There were 20 patients diagnosed with transsexual uterine fibroids,accounting for 16.95％,with 14 of the ultrasonic elastic images scored from 2 to 3 points,and 70.0％ of them.There were 98 non-transgendered uterine fibroids,accounting for 83.05％ of the total.Among them,the ultrasonically elastic images were scored in 92,accounting for 93.9％ of the total.The determination of the undenatured of uterine fibroids was performed on the basis of the elastic image score =4,its accuracy is 92.2％,specificity of 68.7％,the sensitivity was 96.2％,the positive and negative predictive value of 94.1％ and 76.3％ respectively.The judgment of uterine fibroid degeneration was carried out as standard by the elastic image score of less than 3,its accuracy is 92.2％,specificity of 96.2％,the sensitivity was 68.7％,the positive and negative predictive value of 76.3％ and 94.1％ respectively.Conclusion Real-time ultrasonic elastography is an effective and feasible new ultrasonic diagnostic technique for diagnosing uterine fibroid degeneration in clinic,and through the ROC curve analysis,it is suggested that the elastic imaging technique has positive value for the identification of transsexual uterine fibroids and non-transgendered uterine fibroids.
