Abstract：Objective: To explore a hardness range of longitudinal and circumferential wall of normal common carotid artery by real-time shear wave elastography and ultrafast pulse wave velocity and to investigate the impact factors of the hardness of the artery wall. Methods: 120 cases of normal carotid artery diagnosed by ultrasound were recruited for the study. The real-time shear wave elasticity was performed to obtain the elastic modules(Mean, Max, Min) of the anterior and posterior wall of normal common carotid artery as the longitudinal hardness range of the normal carotid artery wall. The ultrafast pulse wave velocity was performed to obtain the pulse wave velocity of normal carotid artery, including the pulse wave velocity in the beginning of the systole and the pulse wave velocity in the end of the systole of normal carotid artery as the circumferential hardness range of the normal carotid artery wall. Results: The hardness of the anterior wall of the normal common carotid artery was higher than that of the posterior wall under real-time shear wave elastic imaging(P<0.05). The elasticity values(Mean, Max, Min) of the normal common carotid artery wall(posterior and anterior) were positively correlated with the age(P<0.05). The PWVBS and PWVES of normal common carotid artery wall were positively correlated with the age(P<0.05). Conclusion: Real-time shear wave elastography and ultrafast pulse wave velocity can quantitatively assess the hardness of the common carotid artery and provide reference for the diagnosis of vascular related diseases. The hardness range of longitudinal and circumferential vascular wall of normal carotid artery is consistent.
