This study aimed to evaluate the feasibility and accuracy of non-electrocardiogram (ECG)-triggered chest low-dose computed tomography (LDCT) with a kV-independent reconstruction algorithm in assessing coronary artery calcification (CAC) degree cardiovascular disease risk patients receiving maintenance hemodialysis (MHD). In total, 181 MHD who needed CT calcium score (CACS) scannings sequentially underwent non-ECG-triggered, automated tube voltage selection, high-pitch LDCT ECG-triggered...
To investigate the diagnostic performance of CT-based radiomics in detecting cardiac amyloidosis (CA) patients with diffuse myocardial thickening. Patients thickening who underwent coronary CT angiography were retrospectively enrolled from five hospitals. one hospital randomly divided into training and internal test cohorts at a 7:3 ratio, other 4 hospitals constituted external cohort. The diagnosis CA followed established guidelines. Regions interest myocardium delineated to extract...
Background Lipid-rich plaques detected with intravascular imaging are associated adverse cardiovascular events in patients non-ST-segment elevation (NSTE) acute coronary syndrome (ACS). But evidence about the prognostic implication of CT angiography (CCTA) NSTE ACS is limited. Purpose To assess whether quantitative variables at CCTA that reflect lipid content nonrevascularized individuals might be predictors subsequent plaque-related major (MACEs). Materials and Methods In this multicenter...
This study aims to develop a diagnostic model that combines computed tomography (CT) images and radiomic features differentiate indeterminate small (5-20 mm) solid pulmonary nodules (SSPNs). METHODSThis retrospectively enrolled 413 patients who had SSPNs surgically removed histologically confirmed between 2017 2019.The included malignant (n = 210) benign 203).The least absolute shrinkage selection operator was used for feature selection, random forest algorithms were construction.The...
Aims This study aimed to assess the diagnostic performances of dual-energy computed tomography (CT)-derived iodine concentration and effective atomic number (Z eff ) in early-phase cardiac CT detecting left atrial appendage (LAA) thrombus differentiating from spontaneous echo contrast (SEC) patients with fibrillation using transesophageal echocardiography (TEE) as reference standard. Methods results A total 389 were prospectively recruited. All underwent a single-phase scan third-generation...
Objective Delayed enhancement cardiac CT is a reliable tool for the diagnosis of left atrial appendage thrombus but limited scanning heterogeneity. We aimed to explore improvement 1 and 3-min delay phase at diagnostic level detect thrombus, in order set up reasonable scheme. Materials Methods A total 6,524 patients were continuously retrieved from January 2015 September 2020 retrospectively. The had undergone Transesophageal echocardiography (TEE) with complete period include arterial phase,...
The hemorheological changes during invasion and metastasis in mice injected with uterine cervix carcinoma U14 were studied. tumor cells transplanted subcutaneously into 615-strain inbred mice. Animals sacrificed at days 5, 9, 15 19. Every mouse was examined histologically viscosity tests performed, including determination of plasma viscosity, blood hemotocrit aggregation red cells. results the histological examination showed that is slightly apparent 5 after transplantation (grades I–III)....
