Diffusion-weighted MRI imaging is an emerging technique
to assess bone marrow abnormality. Normal values may
need to adapt for age and anatomic location to avoid
misinterpretation. Previous studies showed contradictory
results whether bone marrow diffusivity changes with age
and focus on lumbar region only. The purpose of this
study was to evaluate the regional differences and
age-related changes of ADC values in vertebral bone
marrow by measuring ADC values in cervical, thoracic,
lumbar, sacral and both iliac bone marrow in healthy
adults. Current study may give an insight to establish
the normal ADC values on vertebral column for future
references.
