之前的研究使用了痕和BZ定义的灵活值,但它们对ADAS-3D测量的影响尚不清楚.

研究的目的:

用不同的值来量化ADAS-3D测量的变化,用于密集的痕和BZ.

主要方法:

87名心肌梗塞患者接受CMR的回顾性观察研究.
通过ADAS-3D软件处理的CMR图像.
通过使用9种值组合 (55-65%用于密集的痕,35-45%用于BZ) 来比较痕测量.

主要成果:

在所有痕参数的显著差异 (P < .001) 跨值.
在所有值设置中,没有患者的BZ通道计数一致.
观察到的BZ通道数和质量的差异高达200%;最大10个绝对通道差异.

结论:

值变化导致ADAS-3D痕量化的统计学上显著,高幅度的变化.
这些发现强调了值选择对基于CMR的痕评估的关键影响.

Healing II: Complications

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
