概括
超光谱成像 (HSI) 可以通过分析色度特征和色素孔度来区分太阳晶状体和后炎性超色素 (PIH). 与太阳能晶相比,PIH斑点显示出更高的血红蛋白含量和特定颜色值差异.
科学领域:
- 皮肤病学 皮肤病学
- 医疗成像医学成像
- 生物物理学的生物物理.
背景情况:
- 太阳色素和炎症后多发色素 (PIH) 是常见的皮肤色素障碍.
- 精确的区分对于有效的皮肤病治疗至关重要.
- 目前的诊断方法依赖于受过训练的皮肤科医生的视觉评估.
研究的目的:
- 评估超光谱成像 (HSI) 在特征和区分太阳光和PIH之间的有效性.
- 为了识别与每个条件相关的独特色度特征和色素度.
主要方法:
- 超光谱成像 (HSI) 是使用液晶调节过器光谱扫描光谱仪获得的.
- 这项研究包括11名日本女性受试者与太阳能lentigines和5名受试者与太阳能lentigines和PIH.
- 定量分析侧重于氧血球,脱氧血球,黑色素和色度值 (L*,a*,b*) 相对于周围皮肤的差异.
主要成果:
- 在PIH斑点和太阳虫之间观察到ΔOxyhemoglobin,ΔDeoxyhaemoglobin,Δa*和Δb*值的显著差异 (p <0.05).
- 与太阳能豆相比,PIH斑点表现出更高的血红蛋白含量和 Δa* 值,以及较低的 Δb* 值.
- 在两种类型的超色素化之间,在 ΔL* 值或 ΔMelanin 含量上没有发现显著差异.
结论:
- 超光谱成像 (HSI) 显示出在基于不同的色谱和色度特征的基础上,有潜力将太阳晶状体与PIH区分开来.
- 与太阳能晶片相比,PIH斑点的特征是血红蛋白增加和特定的颜色变化 (较高的a*,较低的b*).
- 建议对更大的队列进行进一步的临床研究,以验证HSI在支持这些色素障碍的临床评估中的实用性.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
