The Value of High‐Frequency Ultrasound and Color Doppler Flow Imaging in Assessing the Efficacy of Moderate‐to‐Severe Acne Vulgaris: A Prospective Single‐Arm Study

Puntos clave

• To evaluate the effectiveness of high-frequency ultrasound (HFUS) and color Doppler flow imaging (CDFI) in assessing acne vulgaris severity.
• Conducted a prospective single-arm study
• Used HFUS for visualizing deep acne lesions like nodules and cysts
• Employed CDFI for real-time hemodynamic analysis
• Analyzed severity assessments through both ultrasound grading and clinical evaluation
• HFUS effectively visualized deeper acne lesions, like nodules and cysts
• Ultrasound grading showed slower reduction in severity compared to clinical assessments
• CDFI provided better insights into blood flow and severity
• Combining HFUS and CDFI improved prognostic assessments in moderate-to-severe acne vulgaris
