[Diagnostic value of pulsed Doppler ultrasonography in atherosclerosis of the carotid arteries. A report of 200 cases].
An analysis of ultrasound imaging characteristics and carotid bloodflow parameters in 200 cases of carotid atherosclerosis was made. A high-resolution dual-function ultrasound image displaying instrument was used. It was found that the pulsed Doppler ultrasonography was useful and accurate to help diagnose the presence of extracranial carotid atherosclerotic plaques with narrowing of the carotid arteries. The ratios of the calibres of the internal carotid arteries and the common carotid arteries (IC/CC) could be taken as one of the specific indicators in determining those arteries showing calibre stenosis greater than 50%. Authors suggested that the features of carotid atherosclerosis plaques as identified in the Doppler ultrasonography could be divided into 4 types: 1. coarse type;2. soft type;3. hard type; and 4. mixed type.
