Proper Positioning and Restraint of a Rat Hind Limb for Focused High Resolution Imaging of Bone Micro-architecture Using In Vivo Micro-computed Tomography

DOI: 10.3791/56346-v
What you'll learn
  • ✓ Properly anesthetize and position rat hind limb for µCT imaging
  • ✓ Apply restraint techniques to minimize movement during scanning
  • ✓ Acquire high-resolution bone micro-architecture images for quantitative analysis
Protocol

This paper instructs users of in vivo micro-computed tomography (µCT) scanners how to anesthetize, correctly position and restrain the hind limb of a rat for minimal movement during high-resolution imaging of the tibia. The result is high quality images that can be processed to accurately quantify bone micro-architecture.

Steps

1
Position and restrain rat hind limb for µCT

Anesthetize the rat and position its hind limb in the µCT scanner using proper restraint methods to ensure stability and minimize movement during high-resolution imaging of the tibia.
