ABSTRACT

Introduction: Cartilage is a tissue composed by approximately 80% water. Through magnetic resonance strings it is possible to correlate the tissue’s signal intensity with water content; therefore, the objective of this study was to develop a mathematical model to estimate water content in percentage in a cartilage sample. Material and methods: Through absolute T1 value mapping and inverse recovery sequence magnetic resonance strings 45 agar blocks with progressive and known water concentrations (70-100%) were analyzed. Data obtained was modelled in a lineal regression to obtain a water content prediction equation. Results: The equation water content ~ T1 signal intensity correlates with a r2 = 0.9715 (p ‹ 0.001) with the real water content in the agar blocks. Discussion: T1 magnetic resonance strings provide enough information on the quantity of water present in a tissue with a predictive value near 98%
