Prospective study demonstrates high-frequency ultrasound and color Doppler flow imaging enhance severity assessment in acne vulgaris, suggesting improved clinical evaluations.
HFUS effectively visualizes deep acne lesions (nodules/cysts). Although ultrasound grading demonstrates slower severity reduction than clinical assessment, it provides more objective severity evaluation. CDFI enhances hemodynamic analysis through real-time flow visualization. Combined HFUS/CDFI enables enhanced severity and prognostic assessment in moderate-to-severe acne vulgaris.
