Ultrasound was first introduced in clinical dermatology in 1979. Since that time, ultrasound technology has continued to develop along with its popularity and utility. Today, high-frequency ultrasound (HFUS), or ultrasound using a frequency of at least 10 megahertz (MHz), allows for high-resolution imaging of the skin from the stratum corneum to the deep fascia. This non-invasive and easy-to-interpret tool allows physicians to assess skin findings in real-time, enabling enhanced diagnostic, management, and surgical capabilities. In this review, we discuss how HFUS fits into the landscape of skin imaging. We provide a brief history of its introduction to dermatology, explain key principles of ultrasonography, and review its use in characterizing normal skin, common neoplasms of the skin, dermatologic diseases and cosmetic dermatology.
As frequency advancements in ultrasonography continue, the broad applications of this imaging modality will continue to grow. HFUS is a fast, safe and readily available tool that can aid in diagnosing, monitoring and treating dermatologic conditions by providing more objective assessment measures.
超声于1979年首次引入临床皮肤科。自那时起，超声技术随着其普及和实用性不断发展。如今，高频超声（HFUS），即使用至少10兆赫兹（MHz）频率的超声，能够对从角质层到深筋膜的皮肤进行高分辨率成像。这种非侵入性且易于解读的工具使医生能够实时评估皮肤表现，增强诊断、管理和手术能力。在本综述中，我们讨论HFUS如何融入皮肤成像领域。我们简要介绍其引入皮肤科的历史，解释超声检查的关键原理，并综述其在正常皮肤、常见皮肤肿瘤、皮肤病及美容皮肤科特征描述中的应用。
随着超声检查频率的不断进步，这种成像方式的广泛应用将持续增长。HFUS是一种快速、安全且易于获得的工具，通过提供更客观的评估手段，可辅助诊断、监测和治疗皮肤病。
