Spine fat fraction mapping is emerging with growing
applications in osteoporosis and radiation therapy.
Vertebral bone marrow is characterized by short T2*
relaxation times. Therefore, vertebral bone marrow fat
quantification using chemical shift encoding-based
water-fat imaging needs to correct for T2* decay
effects. The present study compares different approaches
for T2* correction in water-fat imaging of vertebral
bone marrow using single-voxel MRS as a reference
standard. The advantage of a method correcting for a
common T2′ and using a priori known T2 relaxation times
for water and fat components is evaluated on the data
from 26 young healthy volunteers.
