“…With the development of High‐frequency Ultrasonography (HF‐USG) and the realization of power Doppler (PD) on high‐frequency probes, it becomes possible to estimate the acne lesions quantitatively and noninvasively 7 . Previous studies have evaluated the performance of acne on HF‐USG and explored the use of HF‐USG for acne classification 3,5 . However, they did not conduct a quantitative analysis of acne lesions and there was a lack of research on blood perfusion.…”

Objectives-To assess acne vulgaris quantitatively using high-frequency ultrasonography (HF-USG) and power Doppler (PD), and investigate the feasibility and application value of HF-USG and PD in acne vulgaris.Methods-A total of 105 patients with the diagnosis of acne vulgaris in the face referred by a dermatologist were studied prospectively. All the acne patients enrolled were clinically classified by two attending dermatologists independently using three degrees with four levels of classification evaluating only the severest lesion. Gray-scale ultrasound was used to assess the thickness of the lesion, and the thickness ratio was calculated. PD equipped with Qpack semi-quantitative analysis software was used to assess blood signals of the lesion, and Qpack ratio, Qpack peak were calculated. Ten level-4 acne patients were re-evaluated after 2 weeks' treatment, and the results were compared with those before treatment.Results-A total of 105 patients were categorized into four groups by dermatologists, 23 cases were comedones, 33 were papules, 26 were pustules, and 23 were nodules/cysts. There were significant differences in thickness ratio (P < .001), Qpack ratio (P < .001), and Qpack peak (P < .001) among the four groups. For the 10 level-4 acne patients treated 2 weeks by the dermatologist, the difference in thickness ratio between pre-treatment and post-treatment showed no significance (P = .06). However, Qpack ratio and Qpack peak were significantly decreased between pre-treatment and post-treatment (both P = .01).Conclusions-HF-USG and PD equipped with semi-quantitative analysis software can assess acne vulgaris quantitatively, which provides a good basis for the classification and treatment of acne. Their features include thickness ratio, Qpack ratio, and Qpack peak, with Qpack ratio and Qpack peak being the sensitive features for the early efficacy evaluation.

“…HFU of acne comedones reveals widening of the hair follicles and heterogeneous echogenicity of the surrounding dermis instead of cystic lesions. [ 2 ] Confirming the diagnosis of EH is important since EH can be easily improved by the avoidance of hot and humid environments. Dermoscopic studies in Caucasian patients have revealed that EH is characterized by a central homogeneous area, skin-colored or bluish, sometimes surrounded by a pale halo.…”

The advances in dermatologic ultrasound have been significantly influenced by the development of high‐ and ultrahigh‐frequency probes, the provision of guidelines for performing the examinations, and a growing number of publications in the field. This review analyzes the most significant contributions that have impacted the daily practice of dermatologists in recent years. This includes the advances in anatomical detection and the patterns of benign and malignant cutaneous tumors, inflammatory dermatologic conditions, vascular anomalies, nail abnormalities, and aesthetic procedures. The knowledge of these advances is a primer for the operators of these examinations.

High‐frequency ultrasonography and scoring of acne at 20 and 50 MHz

Abstract: The combined use of dermatoscopy and UHFUS may help clinicians to perform an early diagnosis. In particular, the use of UHFUS with both the probes provides a complete evaluation of both the more superficial and deeper parts of the tumour.
