Objective: To explore the differences of conventional ultrasound characteristics, elastic imaging parameters and clinicopathological characteristics of distinct molecular subtypes of breast cancer in young women, and to identify imaging parameters that exhibited significant associations with each molecular subtype.
Methods: We performed a retrospective analysis encompassing 310 young women with breast cancer. Observations were made regarding the ultrasonography and elastography characteristics of the identified breast lesions.
To realize the changes in pulmonary hypertension (PH) patients' right ventricular function. A total number of 74 patients with PH were included, and the parameters of standard echocardiographic were measured as well as the strain of peak longitudinal of each segment during the systole of the right ventricle to calculate the global longitudinal strain (LS) during systole of the right ventricular free wall. ① As pulmonary arterial pressure increased, the right ventricular area gradually increased, and the case group showed the decreased right ventricular fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), and tricuspid annular peak systolic velocity (S') ( < 0.

Objective: To analyze the ultrasonic characteristics of false-negative and false-positive results of shear wave elastography (SWE) in the diagnosis of thyroid nodules to clarify the influence of nodular characteristics on SWE and to guide the clinical application of SWE.
Methods: A total of 435 thyroid nodules from 343 patients with the diagnosis confirmed by surgical pathology were analyzed. Preoperative ultrasonography and SWE were conducted.
Objective: To evaluate the clinical value of qualitative shear wave elastography (SWE) color in the differential diagnosis of benign and malignant thyroid nodules.
Methods: From January 2017 to July 2018, 241 patients with 261 thyroid nodules, who underwent conventional ultrasonography and SWE examination before surgical resection, were enrolled. The nodules were also evaluated by histopathologic analyses.
Objective: The aim of our study was to investigate the value of intraoperative contrast enhanced ultrasound (CEUS) for evaluating the grade of glioma and the correlation between microvessel density (MVD) and vascular endothelial growth factor (VEGF).
Methods: We performed intraoperative conventional ultrasound (CUS) and CEUS on 88 patients with gliomas. All of the patients have undergone surgery and obtained the results of pathology.
Objective: The objective was to assess intraoperative contrast-enhanced ultrasound (CEUS) in traumatic brain surgery.
Methods: We prospectively performed intraoperative conventional ultrasound (IOUS) and CEUS in 32 patients who underwent emergency surgery for the treatment of traumatic brain injury (TBI). Sonographic appearance including echogenicity, border, and size of the traumatic lesion and adjacent brain tissue on CEUS were compared with those on IOUS using surgical results as the gold standard.
Objective: To explore the feasibility and value of intra-operative contrast-enhanced ultrasound in different pathological grades of glioma.
Methods: A total of 46 patients with glioma were selected to undergo the contrast-enhanced ultrasound. They were divided into 3 groups according to their pathological grades.
