Investigation of Hemodynamics and Radiomics Based on High Resolution Magnetic Resonance Imaging for Predicting the Outcomes of Intracranial Dissecting Aneurysm
China208 participantsStarted 2023-01-01
Plain-language summary
This study aims to conduct a comprehensive analysis by integrating clinical factors, aneurysm morphological characteristics, and factors reflecting pathophysiological processes (such as hemodynamic and radiomics features), in order to explore the hemodynamic mechanisms associated with the progression of intracranial dissecting aneurysms. Furthermore, artificial intelligence algorithms will be employed to develop and validate an intelligent risk prediction model for the progression and outcomes of intracranial dissecting aneurysms.

Inclusion criteria
✓. Intracranial dissecting aneurysm clearly diagnosed by DSA and high-resolution MRI imaging (according to the imaging diagnostic criteria proposed in the Chinese Expert Consensus on Imaging Diagnosis of Intracranial Arterial Dissection)
✓. patients managed with conservative treatment and follow-up
✓. patients who agree and sign a written informed consent form
Exclusion criteria
✕. Arteritis, fibromuscular dysplasia, iatrogenic or traumatic pseudoaneurysms
✕. Contraindications to MRI examination (such as claustrophobia or metallic implants), or contraindications to cerebral angiography (such as iodine contrast allergy)
✕. Dissecting aneurysms extending from the extracranial segment to the intracranial segment, or cases with concomitant intracranial atherosclerotic plaques in the affected vessels
✕. Patients who refuse MRI examination
✕. Patients with severe comorbid diseases and an expected survival time of less than 2 years due to these conditions
