简介：
Overview
This study presents a combination of laser Doppler perfusion imaging (LDPI) and laser Doppler perfusion monitoring (LDPM) to measure local blood flows and oxygen saturation in the spinal cord of rats. The standardized procedure for inducing spinal cord trauma aims to enhance understanding of microcirculation following injury.

What is laser Doppler imaging?
Laser Doppler imaging is a non-invasive technique used to measure blood flow in tissues.
How does spinal cord trauma affect blood flow?
Spinal cord trauma can lead to altered blood flow dynamics, impacting recovery and healing.
What are the advantages of using LDPI and LDPM?
These techniques provide real-time data on blood flow and allow for sophisticated analysis over time.
Why is it important to study microcirculation?
Studying microcirculation helps understand the physiological responses to injuries and informs treatment strategies.
What animal model is used in this study?
The study uses a rat model to investigate spinal cord trauma and its effects on blood flow.
