The purpose of this work was to explore the clinical application of quantitative susceptibility mapping(QSM)using an ultrashort echo time (UTE) gradient echo (GRE) sequence in evaluating the bone mineral density(BMD)of lumbar vertebra by analyzing the correlation between QSM and quantitative computed tomography (QCT). Our results showed that there was strong correlation between QSM and QCT. QSM has the potential to be a biomarker providing new insights into osteoporosis.
