[Radiological study of the internal carotid artery].
Three radiologic methods are used to investigate the internal carotid artery. The main indication of CT scan is the assessment of brain ischaemic complications of carotid disease. Magnetic resonance imaging allows in addition to detect dissecting hematomas and carotid flow abnormalities. Cerebral angiography, which owes much to the advent of digital techniques, remains the standard examination of internal carotid artery. Complications of angiography although rare and usually benign explain the recent development of less invasive explorations such as dynamic CT scan and magnetic resonance angiography. This latter method is still under evaluation for diagnosis of carotid stenosis and small size aneurysms.
