ABSTRACT Background Transjugular intrahepatic portosystemic shunt (TIPS) placement leads to a reduction in portal pressure and an improvement survival patients with recurrent refractory ascites variceal haemorrhage. Prediction of post‐TIPS is primarily determined by factors identified before the TIPS procedure, as data collected during or after implantation are limited. The aim study was evaluate influence early hemodynamic changes on survival, order refine post management. Methods In this...
Artificial intelligence (AI) has a multitude of applications in cancer research and oncology. However, the training AI systems is impeded by limited availability large datasets due to data protection requirements other regulatory obstacles. Federated swarm learning represent possible solutions this problem collaboratively models while avoiding transfer. these decentralized methods, weight updates are still transferred aggregation server for merging models. This leaves possibility breach...
The aim of this study was to evaluate the influence different weighting factors on contrast enhancement, signal-to-noise ratio (SNR), and image quality in fusion dual energy computed tomography (DECT) angiography.Fifteen patients underwent a CT angiography aorta with SOMATOM Definition Dual Source (DSCT; Siemens, Forchheim, Germany) mode (tube voltage: 80 140 kVp; tube current: 297 eff. mA 70 mA; collimation, 14 x 1.2 mm). Raw data were reconstructed using soft convolution kernel (D30f)....
Purpose To investigate the efficacy and safety of irreversible electroporation (IRE) in treatment hepatic tumors not suitable for thermal ablation (radiofrequency [RFA] or microwave ablation). Materials Methods This was an institutional review board-approved prospective study 29 patients (15 men, 14 women; mean age, 63 years ± 12 [standard deviation]) with 43 primary (n = 8) secondary 35) malignant liver who underwent computed tomography (CT)-guided IRE. All target were located immediately...
Purpose To determine the relationship between target lesion selection with use of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and classification therapeutic response patients metastatic cancer undergoing systemic cytotoxic and/or targeted therapies. Materials Methods This prospective multireader study was conducted July 2015 2017. Three hundred sixteen consecutive participants underwent 932 CT examinations to monitor treatment. studies were independently read by three...
Abstract Objectives The aim of this study was to compare success, technical complexity, and complication rates percutaneous transhepatic biliary drainage (PTBD) in patients with dilated vs. nondilated bile ducts. Methods In a retrospective analysis, we evaluated all consecutive PTBD performed our department over period 5 years. Technical data (side, fluoroscopy time, radiation dose, amount contrast media, use disposable equipment), procedure-related complications peri-interventional...
This study investigates the associations between early childhood adversities, stress perception, and fibromyalgia syndrome (FMS). Although interconnection dysregulated systems FMS is well documented, adversities remains less understood. explores relationship of early-life by examining its mediation through perceived stress, acute chronic endocrine indicators. Stress was assessed using scale, as salivary hair cortisol indicators respectively. The sample consisted 99 individuals with 50...
<ns4:p>Here we present a dataset with description of portrayed emotions in the movie ”Forrest Gump”. A total 12 observers independently annotated emotional episodes regarding their temporal location and duration. The nature an emotion was characterized basic attributes, such as arousal valence, well explicit category labels. In addition, annotations include record perceptual evidence for presence emotion. Two variants were separately: 1) audio-movie version Forrest Gump that has been used...
Purpose We conducted a systematic analysis of factors (manual vs automated and unidimensional 3-dimensional size assessment, impact different target lesion selection) contributing to variability response categorization in the Response Evaluation Criteria for Solid Tumors 1.1. Patients Methods A total 41 female patients (58.1 ± 13.2 years old) with metastatic breast cancer underwent contrast-enhanced thoracoabdominal computed tomography initial staging first follow-up after systemic...
Abstract Purpose To investigate efficacy and patency status of stent graft implantation in the treatment hepatic artery pseudoaneurysm. Materials Methods A retrospective analysis patients who had undergone endovascular pseudoaneurysms between 2011 2020 was performed. Medical records were examined to obtain patients’ surgical histories screen for active bleeding. Angiographic data on vascular access, target vessel, material used technical success, defined as exclusion pseudoaneurysm by means...
Accurate measurement is crucial for the assessment of tumor dimensions to allow accurate evaluation response. Thus, purpose our study was assess accuracy semi-automated RECIST and volumetric measurements liver lesions in a phantom with different CT acquisition parameters.A upper abdomen 14 hepatic sizes (diameter: 12.0-40.0 mm), densities (45/180 HU at 120 kV), or alignment (vertical/transverse) scanned 16-slice multidetector row computed tomography using varying tube currents...
To determine 30-day-mortality rates and identify predictors for survival in patients undergoing endovascular revascularization acute mesenteric ischemia (AMI) due to occlusion of the celiac (CA) or superior artery (SMA) from arterial thrombosis setting atherosclerosis at vessel origin.A retrospective analysis on who underwent treat AMI caused by thrombotic CA and/or SMA between January 2011 December 2019 was conducted. were calculated. Univariate binomial logistic regression analyses (p <...
Abstract Introduction Fibromyalgia syndrome (FMS) is a chronic disorder characterized by widespread musculoskeletal pain, fatigue and tenderness closely associated with high levels of stress. FMS therefore often considered stress-related disease. Methods A comparative study was conducted 99 individuals diagnosed control group 50 pain-free individuals. Stress indicators were classified into three categories: perceived stress assessed using the Perceived Scale, daily average salivary cortisol...
To evaluate the reliability of global left ventricular (LV) function and mass measurements with aid a semi-automated (Circulation; Siemens, Forchheim, Germany) new fully automated software (Philips Research Europe, Aachen, versus an established manual segmentation method (Argus; Siemens).Forty-one patients (31 men, 10 women; mean age: 62 +/- 5 years) known or suspected coronary heart disease underwent contrast-enhanced Dual-Source computed tomography (120 kV, 410 mAs/rotation, collimation 2...
