This review paper aims to critically evaluate the role of different imaging modalities for their suitability in the diagnosis and treatment of cerebral aneurysms. The standard imaging techniques for visualising the intracranial vascular structures – computed tomography angiography (CTA), magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) – will be evaluated along with the impact of new innovations when increasing the sensitivity of each modality. Surgical and endovascular methods of intervention, including microsurgical clipping, endovascular coiling and flow diversion, will be compared and discussed with additional mention of the role of the radiographer, radiation protection and patient safety.
Cerebral or intracranial aneurysms (IAs) are pathological focal dilations in the walls of blood vessels in the cerebrum. An estimated 85% of IAs occur at junctions of the anterior circulation of the Circle of Willis, an anastomotic ring of arteries that connect the anterior...
