Multimodal Ultrasound Imaging Assessment on Keloid

Skin keloids are common dermatological conditions that can lead to physical limitations, functional impairments, and deformities. Beyond the physiological implications, the aesthetic ramifications of keloids can also result in significant psychological distress, including anxiety and depression, causing both physical and emotional suffering to the affected individuals. The incidence of keloids is high, characterized by their chronicity, resistance to treatment, and high recurrence rate. They have become one of the most challenging conditions to treat across burn surgery, plastic surgery, and dermatology disciplines. The lack of standardized clinical treatment guidelines globally, combined with an absence of a well-defined standardized evaluation system, means that the effectiveness of various treatments is not consistently and objectively assessed, creating significant challenges in clinical applications. This project integrates traditional high-frequency ultrasound with cutting-edge technologies like real-time shear wave elastography and ultra-micro blood flow imaging. By using multimodal ultrasound, investigators aim to observe the therapeutic response of 90Sr-90Y patch treatment on skin keloids. Investigators seek to determine the objectivity and quantification role of multimodal ultrasound data and indicators in assessing keloid severity, including blood flow information and elasticity hardness. Another goal is to obtain quantitative data on keloid thickness, volume, stiffness, and microvascular distribution before and after treatment to monitor the therapy response. This would address the current limitations of subjective keloid scoring scales. It would also serve as an objective assessment standard for precise diagnosis, treatment, and follow-up of keloids in a clinical setting, thereby standardizing the clinical diagnosis and treatment of keloids.
