- Abstract: To investigate the application value of slanted gel pads in carotid ultrasonography by comparing the parameters obtained by slanted gel pads with different angles. Methods The right common carotid artery was examined by ultrasonography in 50 adult patients with negative carotid artery ultrasonography. The peak systolic velocity （PSV，cm /s） and Doppler Angle of the common carotid artery were measured without and with the use of slanted gel pads of 18°，25° and 32°. Results The PSV of common carotid artery was 90.10±8.12 cm/s，84.42 ±7.91 cm/s，78.30 ±7.88 cm/s，（72.25 ±7.62）cm/s without and with the use of slanted gel pads of 18°，25° and 32°，the differences were statistically significant（P<0.01）；The Doppler angle correction were（59.78±0.51）°，（54.92±1.51）°，（50.78± 2.48）° and （46.22±2.82）°，respectively. The differences were statistically significant（P<0.01），and the CV were 0.008，0.027，0.049 and 0.061，respectively.Conclusion Increasing the angle of slanted gel pads can significantly reduce the carotid artery PSV and Doppler angle，potentially improve the accuracy of ultrasonic evaluation of carotid artery flow velocity，and has no obvious effect on the coefficient of variation of PSV.
