Standard Test Method for Evaluating Growth of Engineered Cartilage Tissue using Magnetic Resonance Imaging
1.1 This standard is intended as a standard test method for engineered cartilage tissue growth evaluation using MRI.

1.2 This standard is intended for use in the development of tissue engineering regenerative medical products for cartilage damages, such as in knee, hip, or shoulder joints.

1.3 This standard has been prepared for evaluation of engineered cartilage tissue growth at the preclinical stage and summarizes results from tissue growth evaluation of tissue-engineered cartilage in a few notable cases using water spin-spin relaxation time, T2, in vitro and in vivo in small animal models.

1.4 This standard uses the change in mean T2 values as a function of growth time to evaluate the tissue growth of engineered cartilage.

1.5 This standard provides a method to remove the scaffold contribution to the tissue growth evaluation.

1.6 Information in this standard is intended to be applicable to most porous natural and synthetic polymers used as a scaffold in engineered cartilage, such as alginate, agarose, collagen, chitosan, and poly-lactic-co-glycolic acid (PLGA). However, some materials (both synthetic and natural) may require unique or varied methods of MRI evaluation that are not covered in this test method.
