Is there a simple and accessible solution to improve acute infarct core imaging? The utility of steady-state CT angiographic source images obtained from a delayed phase acquisition.

Background: Early identification and quantification of core infarct is of importance in stroke management for treatment selection, prognostication, and complication prediction. Non-contrast computed tomography (CT) (NCCT) remains the primary tool, but it suffers from limited sensitivity and inter-rater variability; CT perfusion is inconsistently available and commonly blighted by movement artefact. We assessed the performance of a standardised form of CT angiographic source imaging (CTASI) obtained through addition of a delayed phase at 40 seconds post-contrast injection (DP40) following fast-acquisition CT angiography.

Department of Neurosurgery, Shaoxing People's Hospital, Shaoxing, China.
Objective: Endovascular mechanical thrombectomy (EVMT) is widely employed in patients with acute intracranial carotid artery occlusion (AIICAO). This study aimed to predict the outcomes of EVMT following AIICAO by utilizing anatomic classification of the circle of Willis and its relative position to the thrombus.
Methods: In this study, we retrospectively analyzed a cohort of 108 patients with AIICAO who underwent endovascular mechanical thrombectomy (EVMT) at Shaoxing People's Hospital.
Combined technique versus stent-retriever alone: Interaction analysis of angioarchitectural and technical features.
Interv Neuroradiol
January 2025
Department of Neurology, Emory University School of Medicine-Atlanta, GA, USA.
Introduction: We aimed to explore if anatomical and technical features could interact and favor the chances of reperfusion according to the treatment strategy: combined technique (CoT) of mechanical thrombectomy (MT) with contact aspiration and stent-retriever (SR) versus SR alone.
Methods: Retrospective analysis of a prospective MT database for carotid terminus or MCA-M1 occlusion, first-line SR alone or CoT, and angiographic run with SR deployed on the first pass. The primary analysis involved the interaction between clinical and angiographic characteristics and first-line MT modality on first-pass effect (FPE; first pass eTICI2c-3).
Development and validation of a novel coronary artery disease risk prediction model.
J Transl Med
January 2025
Department of Cardiology, The 904th Hospital of the PLA Joint Logistics Support Force, Wuxi, Jiangsu, 214044, People's Republic of China.
Objective: This study aims to develop a novel risk assessment tool for coronary artery disease (CAD) based on data of patients with chest pain in outpatient and emergency department, thereby facilitating the effective identification and management of high-risk patients.
Methods: A retrospective analysis was conducted on patients hospitalized for chest pain. Patients were divided into a control group and a CAD group based on angiographic results.
Microvascular Plug Embolization of Anterior Spinal Artery Bearing Segmental Arteries Prior Aortic Stenting: Technique and Safety.

January 2025
Department of Radiology, University Hospital, Ludwig Maximilian University of Munich, Munich, Germany.
Purpose: This study aims to present our experience with superselective embolization of the anterior spinal artery-bearing segmental artery (ASAbSA) using a microvascular plug (MVP) during the minimally invasive segmental artery coil embolization (MISACE) procedure prior endovascular repair of the thoracoabdominal aortic aneurysms.
Methods: We retrospectively evaluated all MISACE procedures performed between May 2018 and July 2023, where MVP was deployed into an angiographically confirmed ASAbSA. Data were analyzed regarding interventional details, technical aspects, and safety protocols.
