Abstract: Objective: To explore the value of shear wave elastography in quantitatively identifying keloids and hypertrophic scars. Methods: Thirty patients with clinical diagnosis of keloid and thirty with hypertrophic scar were selected. The gender, age, and long-axis section shear wave elastography Young's modulus values of the lesions in the two groups were compared. Results: The long-axis section shear wave elastography Young's modulus values of the keloids and hypertrophic scars were (94.93±25.39)kPa、(24.5±3.62)kPa, with a significant difference (P＜0.001).  Conclusion: The tissue hardness of the keloids and hypertrophic scars can be quantitatively evaluated by shear wave elastography, which is helpful for the clinical identification of the two diseases.
