As the high-resolution multifrequency transducers and multichannel color Doppler machines have been developed, dermatologic ultrasound imaging has been rapidly growing in recently years [1]. Joint Ultrasonography (US) in psoriasis [2] and hair morphology by US in androgenetic alopecia [3] have been also studied in current dermatologic ultrasound. Now, acoustic coupler, namely SF001 for superficial or proximal observation has been developed [4]. The usefulness of the acoustic coupler, SF-001 has been reported in
the joint US of rheumatoid arthritis [4]. We have experienced the use of acoustic coupler for the dermatologic lesion for panniculitis due to the venous insufficiency condition in the lower extremity and superficial lipoma in the thigh location. We have described the advantages of this procedure in detail.
