Utility of High-Resolution Ultrasonography by Using Acoustic Coupler in Dermatology

Abstract

We have described the experience using the acoustic coupler for subcutaneous angiolipoma comprehensively diagnosed in the lower extremity. The feature of ultrasonography (US) image with the acoustic coupler is more clearly depicted, particularly in superficial or near-field location. The usefulness of this procedure has been demonstrated as stableness state, equipped condition, and satisfactory observation for vasculature status due to the low attenuation material as previously described. The author will also recommend the observation with acoustic coupler for dermatologic superficial lesion, especially, rough, unevenness part in hand, foot, and joint location without copious amount of gel. We will indicate that acoustic coupler is useful for the appropriate condition to depict the accurate imaging on Real-Time Tissue Elastography (RTE). The author will suggest that this procedure can contribute to the accurate US diagnosis for dermatological superficial lesion, especially dermal involvement without a generous amount of gel.

Acral Calcified Angioleiomyoma Along with Radiological Features

“…Recently, the study using the ultra-highfrequency ultrasound in the evaluation of pediatric pilomatricoma has been reported [11]. The author usually performs US studies for dermatologic fields with a high-resolution, broad-band (5MHz-18MHz) linear transducer (Nobulus Hitachi, Ltd.Tokyo, Japan) and described several reports in the dermatologic area [2,4,5,[12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Characteristic Appearances of Peripheral Schwannoma on High-Resolution Ultrasonography And MRI: Comparison Between Antoni A-Dominant and Antoni B-Dominant Types

“…Recently, Yang et al [2] described that the target sign is a prominent feature on US in peripheral schwannoma. The author usually performs US studies for dermatologic fields with a high-resolution, broad-band (5MHz-18MHz) linear transducer (Nobulus Hitachi, Ltd. Tokyo, Japan) and described several studies including schwannoma [4][5][6][11][12][13][14][15][16][17][18][19][20][21][22].…”

High-Resolution Ultrasonographic Appearances in Superficial Fibromatoses: Palmar and Plantar Diseases

“…The author has previously described anatomy in dermatological ultrasound [16]. Klauser et al [17] suggested that red is used to represent softer tissues, blue represents harder tissues, and yellow or green represent intermediate tissue elasticity on sonoelastography.…”

“…We usually perform US studies for dermatologic fields with a high-resolution, broad-band (5MHz-18MHz) linear transducer (Nobulus Hitachi, Ltd.Tokyo, Japan). We have also provided several reports of the dermatologic lesion [5][6][7][8][9][10][11][12][13][14][15][16].…”
