Abstract
Intracranial aneurysms (IAs) are a critical public health concern: they are asymptomatic and can lead to fatal subarachnoid hemorrhage in case of rupture. Neuroradiologists rely on advanced imaging techniques to identify aneurysms in a patient and consider the characteristics of IAs along with several other patient-related factors for rupture risk assessment and treatment decision-making. The process of diagnostic image reading is time-intensive and prone to inter- and intra-individual variations, so researchers have proposed many computer-aided diagnosis (CAD) systems for aneurysm detection and segmentation. This paper provides a comprehensive literature survey of semi-automated and automated approaches for IA detection and segmentation and proposes a taxonomy to classify the approaches. We also discuss the current issues and give some insight into the future direction of CAD systems for IA detection and segmentation. • A comprehensive literature survey of intracranial aneurysm detection and segmentation from the past two decades. • A taxonomy for classifying and comparing approaches of aneurysm detection and segmentation. • Identifying trends and challenges in automated intracranial aneurysm detection and segmentation, offering insights into methodology evolution and future directions for research and clinical use.
