Fat quantification of multifidus muscle using T2-weighted Dixon: which measurement methods are best suited for revealing the relationship between fat infiltration and herniated nucleus pulposus

Objective To reveal the best-suited method for fat quantification of lumbar multifidus to demonstrate its relationship to herniated nucleus pulposus (HNP) using T2-weighted Dixon. Materials and methods One hundred eight patients who underwent MRI for low back pain were enrolled. Two readers independ...

Description
Summary:Objective To reveal the best-suited method for fat quantification of lumbar multifidus to demonstrate its relationship to herniated nucleus pulposus (HNP) using T2-weighted Dixon. Materials and methods One hundred eight patients who underwent MRI for low back pain were enrolled. Two readers independently analyzed the fat fraction (Ff) using axial two-dimensional (D), coronal 2-D, and coronal 3-D measurement. Pearson’s correlation coefficient was calculated between age, body mass index (BMI), and the Ff, and age, sex, BMI, and Ff were compared between ‘HNP group’ and ‘no HNP group’. Multivariate logistic regression analysis was performed to identify factors associated with HNP. Results Coronal 2-D Ff showed the highest correlation with age ( r  = 0.536, P
