Abstract
Neuroradiology utilises a wide range of imaging modalities in the diagnosis and treatment of CNS pathologies. MRI is the investigation of choice for most neuroradiological imaging. CT remains the foremost modality in the emergency situation, and is superior to MRI in the visualisation of calcification, bone detail and acute hemorrhage. Angiography should be considered for all patients without a clear cause of hemorrhage and who are surgical candidates. Digital subtraction angiography is currently the gold standard in the investigation of subarachnoid hemorrhage, but in the future MRA and CTA will replace it. Technological advances are moving towards less invasive imaging modalities, supported by functional and physiological data. Ultrasound is the primary investigation in a neonate with an enlarging head and will reliably diagnose ventriculomegaly. It is accurate in the assessment of internal carotid artery stenosis for potential carotid endarterectomy patients.
