We conducted a study to investigate the consistency of
percent breast density measured in MRI in four different
positions and imaging resolution. The breast and
fibroglandular tissue segmentation was based on an
established novel method. Results of FV and PD
measurement show small variations, with an averaged CV
of <9%, among the four MR studies. Remarkable
measurement variation did occur in some subjects in
hands-down position, compared to hands-up position. The
results from our MR consistency study indicate that MR
imaging data from multi-centers, regardless of patients
positions (hand-up or hands-down), can be combined for
analysis.
