title: [Ultrasound Doppler examination of the carotid artery].
abstract: Ultrasound-Doppler examination of the carotid artery is employed to an increasing extent in investigation of patients with cerebrovascular disease. The diagnostic criteria and results achieved with the various forms: continuous wave Doppler, duplex scanning and colour-Doppler, are described. In the two latter methods, the accuracy is high in the diagnosis of occlusions, quantitating of all degrees of stenosis and also in identification of normal vessels. On comparison with arteriography, the accuracy is stated to be typically 85-95%. The reproducibility of the method is high and equivalent to the results obtained by assessment of the same arteriography by two independent radiologists. The sources of error are discussed and it is concluded that ultrasound-Doppler examination of the carotid artery should replace arteriography in the primary investigation of patients with cerebrovascular disease.
