What is magnetic resonance elastography?
Magnetic resonance elastography (MRE) is a non-invasive imaging technique used to assess the mechanical properties of tissues.
How does μMRE differ from traditional MRE?
μMRE is specifically designed for measuring the mechanical properties of small soft tissues with higher resolution.
What are the advantages of non-invasive testing?
Non-invasive testing preserves the integrity of samples and allows for repeated measurements over time.
What role do biomaterial scaffolds play in tissue engineering?
Biomaterial scaffolds provide a structure for cells to grow and form engineered tissues.
What is the significance of using a laser Doppler vibrometer?
A laser Doppler vibrometer accurately detects motion and helps characterize the mechanical properties of the tissue samples.
