Papillary Dermis01:11

Papillary Dermis

6.8K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Reticular Dermis01:15

Reticular Dermis

5.5K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

科学领域:

  • 生物材料科学 生物材料科学
  • 放射学 放射学是一门学科.
  • 整形外科 整形外科 整形外科

背景情况:

  • 无细胞皮肤基质 (ADM) 是一种来自尸体皮肤的无细胞,免疫无效的移植.
  • 它在重建性手术中充当支架,特别是在乳房切除术后的乳房重建中,以支持乳房植入物并填补缺陷.
  • ADM提供了诸如改善化品结果和减少囊收缩率等好处.

研究的目的:

  • 在超声波,乳房影像和MRI上描述细胞皮肤基质 (ADM) 的成像特征.
  • 强调临床背景在区分ADM与恶性瘤方面的重要性.
  • 帮助放射科医生准确诊断,避免不必要的活检.

主要方法:

  • 对各种模式 (超声波,乳房学,图解合成,MRI) 的ADM成像发现的审查.
  • 图像检测结果与手术内配置和组织病理学结果的相关性.
  • 强调对ADM在乳腺重建中的使用的临床知识.

主要成果:

  • 在超声波上,ADM看起来像一个微妙的带或一个可触摸的圆形质量,具有可变的回声性.
  • 乳房影像和断层合成可能会显示ADM作为一个周边的圆形质量,可能具有层次的外观.
  • 关于增强的MRI发现有所不同,其组织病理学可能类似于痕组织.

结论:

  • 对ADM的成像发现是可变的,取决于宿主组织的结合.
  • 熟悉ADM的外观和手术内使用对于准确诊断至关重要.
  • 在成像上区分ADM与恶性瘤可以防止不必要的干预.
