Trichology is the area of dermatology that focuses on the study, diagnosis and management of the different types of alopecia and hair and scalp disorders. In recent years, there have been great advances in the non-invasive diagnosis of these conditions, especially with trichoscopy and more recently with sonography. High frequency ultrasound study of the scalp, for which we propose the name of "trichosonography", may represent a valuable technique in the evaluation of both clinical and subclinical abnormalities of the hair follicle and the innermost layers of the skin, which are otherwise inaccessible to trichoscopy. The purpose of this pictorial essay is to offer a descriptive approach to the clinical and ultrasound findings of the main hair and scalp disorders.
毛发学是皮肤病学的一个领域，专注于研究、诊断和处理不同类型的脱发以及毛发和头皮疾病。近年来，这些病症的非侵入性诊断取得了巨大进展，尤其是在毛发镜检查方面，以及最近在超声检查方面。我们提议将头皮的高频超声研究命名为“毛发超声检查”，它可能是评估毛囊和皮肤最内层临床及亚临床异常情况的一项有价值的技术，而这些情况用毛发镜检查是无法触及的。这篇图谱文章的目的是对主要毛发和头皮疾病的临床及超声检查结果提供一种描述性方法。
