dc.description.abstract | This document details procedures for PDFF measurement in MF mouse tibia to achieve stated performance claims.In this profile PDFF values are expressed in “% units” on a 0 to 100% scale, such that bone marrow containing dominant red marrow and dominant yellow marrow have PDFF values of 0-few% and 80-100%, respectively. Tibia bone marrow composition in MF mouse models has gradation going from proximal to distil ends of the tibia, therefore separate claims are made for volume of interest (VOI) analysis of PDFF maps for each of three distinct sections along the length of the tibia (see Figure 1): Section 1 (proximal)º VOI (~4-5mm3) within 9mm of proximal end of tibia Section 2 (transition)º VOI (~0.4-0.5mm3) from 10 to 12mm of proximal end of tibia Section 3 (distil)º VOI (~0.1-0.2mm3) from 13 to 14mm of proximal end of tibia Claim 1:A measured change in the mean PDFF in Section 1 VOI of MF mouse model tibia that exceeds ±1.6% indicates a true biological change has occurred in the tibia bone marrow with 95% confidence. Claim 2:A measured change in the mean PDFF in Section 2 VOI of MF mouse model tibia that exceeds ±15.5% indicates a true biological change has occurred in the tibia bone marrow with 95% confidence Claim 3:A measured change in the mean PDFF in Section 3 VOI of MF mouse model tibia that exceeds ±25.5% indicates a true biological change has occurred in the tibia bone marrow with 95% confidence. | |
