A study on the efficacy of microwave ablation for benign thyroid nodules and related influencing factors.

Objectives: To explore the efficacy of microwave ablation (MWA) in the treatment of benign thyroid nodules, and analyze related influencing factors.

Methods: The clinical and ultrasound data of 115 patients with 115 benign thyroid nodules treated with MWA were retrospectively analyzed. The volume of nodules at 1, 3, 6, and 12 months after the procedure was obtained, and the volume reduction rate (VRR) at each time point was calculated.

Prognostic potential of layer-specific global longitudinal strain in patients with non-ST-segment elevated acute coronary syndrome and preserved left ventricular ejection fraction.

This study sought to investigate the prognostic potential of layer-specific global longitudinal strain (GLS) in predicting cardiac events among non-ST-segment elevated acute coronary syndrome (NSTE-ACS) patients with preserved LVEF. In this prospective study, we enrolled 160 consecutive NSTE-ACS patients with preserved LVEF (≥ 50%) who underwent successful percutaneous coronary intervention (PCI). Transthoracic two-dimensional echocardiography examinations were performed within 48 h of admission (before PCI).

Using neutrosophic graph cut segmentation algorithm for qualified rendering image selection in thyroid elastography video.

Recently, elastography has become very popular in clinical investigation for thyroid cancer detection and diagnosis. In elastogram, the stress results of the thyroid are displayed using pseudo colors. Due to variation of the rendering results in different frames, it is difficult for radiologists to manually select the qualified frame image quickly and efficiently.

Ultrasound utility for predicting biological behavior of invasive ductal breast cancers.

Purpose: The aim of the study was to evaluate the correlation of ultrasound features with breast cancer molecular status.

Materials And Methods: A retrospective review was performed of ultrasound findings in 263 patients diagnosed with breast invasive ductal carcinoma for comparison with immunohistochemistric results were obtained from each lesion. Relationships between ultrasound findings and molecular status were investigated by using multiple regression analysis by means of stepwise logistic regression.

Association of conventional risk factors for cardiovascular disease with IMT in middle-aged and elderly Chinese.

To study the association between known risk factors for cardiovascular disease and intima-media thickness (IMT) in the carotid and popliteal arteries in middle-aged and elderly Chinese adults. 686 middle aged and elderly Chinese adults from the China Da Qing Diabetes Prevention Study who had full clinical, laboratory, ultrasound examination results were enrolled in the study. Common carotid artery (CCA) and popliteal artery (PA) IMT were obtained using high resolution ultrasound machine.

The value of strain ratio in differential diagnosis of thyroid solid nodules.

Objective: To assess the clinical value of strain ratio in differentiating thyroid solid nodules and explore its distribution characters based on pathological results.

Materials And Methods: The study was approved by the ethic committee and the informed consents were signed. Ninety nine solid thyroid nodules (67 benign and 32 malignant) from 71 female (mean age 46.

[Quantitative evaluation of myocardial perfusion and regional systolic function by myocardial contrast stress echocardiography with computer-assisted technique in ischemic myocardium of rabbits].

Objective: To evaluate the feasibility and value of determining myocardial perfusion and regional systolic function by myocardial contrast stress echocardiography (MCSE) with computer-assisted technique in a rabbit model of ischemia/reperfusion injury.

Methods: Rabbits underwent 30-(Group I, n = 15) and 120-(Group II, n = 15) minute left ventricular branch of the left circumflex coronary artery occlusion foll owed by 60-minute reperfusion, dobutamine at increasing doses (5, 10, 15 and 20 microg.kg(-1).

Study of normal Chinese vertebral-basilar arteries with transcranial color Doppler flow imaging.

Objective: The aim of this study was to evaluate the blood flow characteristics of intracranial vertebral-basilar artery (V-BA) in healthy Chinese adults with transcranial color Doppler flow imaging (TCDFI) and provide reference values of healthy people of different ages and genders.

Methods: Three hundred healthy Chinese adults were divided into three groups based on their ages: Group I: 20-39 years, Group II: 40-59 years, Group III: >/=60 years. Each group was subdivided into two subgroups according to their gender.
