Objectives The purpose of this study was to assess the clinical value ultrasound (US) features breast lesions for predicting risk axillary lymph node metastasis in patients with cancer. Methods In retrospective study, 425 cancer were recruited, and their preoperative US postoperative pathologic results collected. association these determined by univariate multivariate analyses. Results Among patients, 200 (47.1%) had metastasis, 225 (52.9%) did not. parameters tumor shape, color Doppler flow...
To explore the value of contrast-enhanced ultrasound (CEUS) in differential diagnosis molecular subtypes breast cancer. Sixty-two cases cancer were divided into luminal epithelium A or B subtype (luminal A/B), Her-2 over-expression and triple negative (TN). CEUS routine ultrasonography performed for all patients before surgery. (1) The contrast enhancement pattern was more likely to present with radial edge (76.92%, p < 0.05) low perfusion (69.23%, 0.05). maximum intensity (IMAX) lower (p...
Background and Objectives: Whether the morphological changes in axillary lymph node (ALN) have occurred prior to metastasis remains unclear breast cancer (BC) patients. The aim of this study is investigate influence BC for morphology non-metastasis ALN (N−) and, further, improve performance ultrasound (US) examination (N+). Materials Methods: In retrospective study, 653 patients with mass were enrolled divided into normal group 202 benign tumor, N− 233 negative N+ 218 positive ALN. US...
Objective Based on the ultrasonic characteristics of breast mass and axillary lymph nodes as well clinicopathological information, a model was developed for predicting node metastasis in cT1 cancer, relevant features associated with were identified. Methods Our retrospective study included 808 patients invasive cancer treated at Second Affiliated Hospital Cancer Harbin Medical University from February 2012 to August 2021 (250 cases positive group 558 negative group). We allocated 564...
Abstract Objectives To assess the clinical value of elasticity contrast index (ECI) in differentiating malignant thyroid nodules from benign ones. Methods Conventional ultrasound and elastography with pulsation carotid artery used as compression source were retrospectively reviewed on 175 patients (143 females 32 males; mean ± SD age, 45.17 11.45 years) 236 solid (113 123 benign). All confirmed by fine-needle aspiration or surgery to be accurately diagnosed. Elasticity values computed...
Objectives The aim of this study was to determine whether any salient differences exist in triple‐negative breast cancer (TNBC) between premenopausal and postmenopausal patients by comprehensively comparing the ultrasound (US) clinicopathologic features these patients. Methods A detailed evaluation US 60 tumors from with a diagnosis TNBC (36 24 women) conducted retrospective study. Results Triple‐negative more likely show round or oval shape microlobulated margins, commonly exerted effects...
Objective To evaluate the left ventricular flow field characteristics in patients with obstructive and non-obstructive hypertrophic cardiomyopathy (HCM) using vector mapping (VFM),then assess hemodynamics.Methods 40 HCM were randomly selected as case group,among which 20 outflow tract(LVOT) obstruction (group Ⅰ) without LVOT obstruction(group Ⅱ),40 healthy adult volunteers served control group.The conventional parameters:left ejection fraction(LVEF),interventricular septal thickness radial...
Objective To explore the differential diagnostic value of speckle-tracking imaging (STI) between dilated cardiomyopathy(DCM) and ischemic cardiomyopathy(ICM).Methods 40 DCM patients,32 ICM patients 30 normal controls were enrolled for this study.Different views high frame images left ventricle recorded.The time to peak radial strain,circumferential strain longitudinal 18 myocardial segments measured by STI,and maximum (Ts-dif) standard deviation(Ts-SD) calculated.The ventricular parameters...
Objective To assess right ventricular systolic function using real-time three-dimensional quantitative analysis (RT-3DRVQ) in patients with coronary artery disease (CAD) complicating left heart failure. Methods Sixty-eight diagnosed CAD and failure were selected as the case group. Among them, 38 individuals associated pulmonary hypertension (PH) 30 without. Another healthy people recruited control Conventional echocardiographic parameters, well free wall septum longitudinal strains of...
Objective To explore the value of contrast-enhanced ultrasound (CEUS) in differential diagnosis different molecular subtypes breast cancer. Methods Sixty-two cases cancer patients with 62 lesions confirmed as by postoperative pathology were selected. Referencing St. Gallen standard and according to immunohistochemical markers estrogen receptor (ER), progesterone (PR) human epidermal growth factor 2 (Her-2) expression, all divided into Luminal epithelium A or B (Luminal A/B)subtype(26...
The main objective of this study was to determine the predictive value US characteristics for disease-free survival (DFS) in BC patients. We retrospectively analyzed ultrasonic images and clinical data patients who had previously undergone breast surgery at least 10 years before enrollment divided them into a case group control according cutoff 120 months DFS. Correlation analysis performed identify as independent predictors DFS by multivariable logistic regression Kaplan−Meier analysis. A...
This retrospective study aimed to develop and validate an Ultrasound (US)-based nomogram predict short disease-free survival (short-DFS, less than 120 months DFS) in breast cancer (BC).Nomogram was established based on a training data of 311 BC patients by multivariable logistic regression, were assessed discrimination, calibration, clinical usefulness. Risk stratification performed X-tile. An independent testing 200 with used for external validation.Nine predictors including three US...
