Abstract

Nail disorders are frequently a challenge to diagnose correctly only based on clinical findings. Moreover, biopsies may leave scars due to damage to the nail matrix. Currently, high-frequency ultrasound (HFUS) with probes >15 MHz is the first-choice imaging technique to study the nail. Compared with other imaging tests such as computed tomography and magnetic resonance imaging, HFUS has the advantage of high-resolution imaging of the nail apparatus without exposure to radiation, contrast media, and the risk of claustrophobia of these other expensive imaging methods. Notably, the axial spatial resolution of HFUS is higher than computed tomography and magnetic resonance imaging; therefore, it can better discriminate the anatomical alterations. Our objective is to review the main applications of HFUS of the nail through literature analysis and illustration of cases of the most frequent pathologies found in our experience, exemplifying why, how, and when HFUS could help diagnose nail diseases.

指甲的超声波:为什么，如何，何时。

指甲疾病往往是一个挑战，正确诊断仅基于临床表现。此外，活组织检查可能会因指甲基质受损而留下疤痕。目前，探头>15 MHz的高频超声(HFUS)是研究指甲的首选成像技术。与计算机断层扫描(CT)和磁共振成像(MRI)等其他成像方法相比，HFUS具有高分辨率趾甲成像的优势，无需暴露于辐射、造影剂，也不会像其他昂贵的成像方法那样存在幽闭恐惧症的风险。值得注意的是，HFUS的轴向空间分辨率高于CT和MRI;因此，它可以更好地识别解剖改变。我们的目的是回顾高频超声(HFUS)在指甲中的主要应用，通过文献分析和我们经验中发现的最常见的病理病例，举例说明高频超声(HFUS)为什么、如何以及何时可以帮助诊断指甲疾病。
