Background: The safety and efficacy of 17-gauge needles used in CT-guided percutaneous cryoablation for lung nodules were explored in this study. The purpose of the study was to compare the findings with earlier research and multi-center clinical trials that used various needle sizes.
Methods: Between 2016 and 2020, a retrospective study was conducted with approval from the institutional review board.
Rationale And Objectives: Selecting region of interest (ROI) for left atrial appendage (LAA) filling defects assessment can be time consuming and prone to subjectivity. This study aimed to develop and validate a novel artificial intelligence (AI), deep learning (DL) based framework for automatic filling defects assessment on CT images for clinical and subclinical atrial fibrillation (AF) patients.
Materials And Methods: A total of 443,053 CT images were used for DL model development and testing.
Setting: Diabetes mellitus (DM) may increase risk of pulmonary tuberculosis (PTB) and influence its radiological manifestations.
Objective: To evaluate the impact of glycemic status on radiological findings of PTB in diabetic patients.
Methods: Between January 2010 and December 2015, chest radiographs (CXRs) in consecutive 214 DM patients with culture-proved PTB and 123 available thoracic computed tomography (CT) scans were enrolled.
Introduction: Patients with traumatic brain injury (TBI) may have concomitant facial fractures. While most head injury patients receive head computed tomography (CT) scans for initial evaluation, the objective of our study was to investigate the value of simultaneous facial CT scans in assessing facial fractures in patients with TBI.
Methods: From January 1, 2015 to December 31, 2015, 1649 consecutive patients presenting to our emergency department (ED) with a TBI who received CT scans using the protocol for head and facial bones were enrolled.
Article Synopsis
- The study aimed to establish an imaging protocol for oral examinations using 320-slice multidetector CT (MDCT), focusing on achieving high image quality while reducing radiation exposure.
- Various scanning techniques, tube voltage, and current settings were tested on a head phantom, assessing both bone and soft-tissue structures to find the best imaging approach.
- The optimal settings identified were 135 kVp, 80 mA, and volume-scanning mode, which provided effective visualization with minimal radiation dose, making it a recommended option for dentomaxillofacial imaging.
Background: It is critical to recognize high risk patients who are prone to develop stroke in the management of atrial fibrillation (AF). The purpose of this study was to identify the determinants of AF related stroke by assessing the anatomical and functional remodeling of cardiac chambers.
Methods: We compared the cardiac structure and function of 28 consecutive patients with paroxysmal and persistent AF-related stroke with 69 patients with AF and 21 controls without stroke using contrast-enhanced 64-slice multi-detector computed tomography during sinus rhythm.
Epicardial adipose tissue (EAT) is positively associated with risk factors for cardiovascular disease, but the role of EAT in the development of atrial fibrillation (AF)-related stroke and its association with the anatomical and functional remodeling of the left atrium (LA) have not been elucidated.This was a comparative cross-sectional study. Twenty-seven patients with paroxysmal or persistent AF and cardioembolic stroke were selected and compared with 68 age- and sex-matched AF patients without stroke.

We sought to evaluate the technical factors associated with safety and outcome of preoperative embolization of pediatric hypervascular brain tumors.
Materials And Methods: Eight pediatric brain tumor patients received preoperative endovascular embolization during the past 8 years.
