Longitudinal 4D monitoring of bone mass and architecture and (re)modeling events using in vivo micro-CT

In the field of preclinical bone imaging, in vivo micro-CT is a powerful tool for the longitudinal monitoring of bones to acquire bone mass and architectural changes in 4D (3D with time). It will also allow 4D longitudinal acquisition of bone remodelling events (formation/resorption) in the same bone by serial registration, stronger statistics and a significant reduction of the number of animals used.

Overview

Studying murine bone (re)modeling events (formation and resorption) over time requires the analysis of bone mass and architecture at several different time points and the use of a large cohort of animals. An alternative approach to this cross-sectional study design, ex-vivo micro-CT and laborious 2D histological analysis is to utilize the power of in vivo micro-CT. This newly emerging technology allows assessment of bone mass and architecture in 3D with time as the 4th dimension. It will also allow 3D image registration to quantify bone formation and resorption between “reference” and “target” timepoints. This powerful tool offers information on bone (re)modelling events along the entire bone in 3D; a major revolutionary advantage over the existing traditional limited methodologies for the assessment of bone. It will also lead to stronger statistics as every animal could serve as its own control. Consequently, fewer animals are used in experiments resulting in a great cost reduction. In this webinar, Dr. Behzad Javaheri will discuss how he has used Bruker’s high-resolution in vivo SkyScan 1176 to perform 4D micro-CT.

What to expect

Dr. Javaheri will describe the benefits of 4D micro-CT to monitor murine bone mass and architecture and the underpinning (re)modelling events driving these changes.
