Filter by:This study (IEDAL study) intends to prospectively enroll more than 6800 patients who will undergo head CT angiography (CTA) scanning in the outpatient clinic. It will be carried out in 25 hospitals in more than 10 provinces in China. The patient's head CTA images will be randomly assigned to the True-AI and Sham-AI group with a ratio of 1:1, and the patients and radiologists are unaware of the allocation. The primary outcomes are sensitivity and specificity of detecting intracranial aneurysms. The secondary outcomes focus on the prognosis and outcomes of the patients.
With the emergence of advanced technology to date in the artificial intelligence (AI), computer aided diagnosis has gradually gained its popularity in the field of healthcare. Particularly, in the clinical practice of coronary artery disease diagnosis, the application of AI could be of great implication in alleviating the shortage of medical sources. To evaluate the effectiveness and safety of the AI-based coronary CT angiographic analysis software (RuiXin-CoronaryAI) for diagnosis of coronary artery stenosis, a retrospective, multi-center, cross-over designed, blinded, sensitivity superiority and specificity non-inferiority clinical trial will be conducted.
Aortic balloon occlusion can be used by emergency physicians to rescue patients with massive bleeding.The purpose of this study is to study the anatomical characteristics of aortic balloon occlusion based on aortic CT angiography, so as to provide evidence for improving the success rate of aortic balloon occlusion guided by body surface markers.
The aim of this study is to compare the effects of Ivabradine and metoprolol to reduce heart rate prior to coronary CT angiography in patients with advanced heart failure.
