Video from RSNA 2017: New program promotes quality in radiology

Nov 28, 2017

With its big, expensive scanners that can cost millions of dollars, radiology is a frequent target of efforts to reduce unnecessary healthcare costs. But what if radiology learned to police itself? Dr. Pamela Johnson of Johns Hopkins University and Dr. Yoshimi Anzai of the University of Utah discuss their efforts to promote quality in radiology by reducing unnecessary imaging.

$Study overview. (A) Volumetric segmentation of the paraspinal musculature was performed for 1,316 participants. (B) Manual segmentation was performed, the results were compared with the volumetric segmentation results, and the Dice score and the intersection over union were calculated. (C) The three-dimensional segmentations from T1 through T10 were individually extracted and combined into a single volume for analyses. (D) Muscle volume and median muscle attenuation were derived from the segmentation volumes. (E) Analyses were performed to assess the correlation of the paraspinal muscle attenuation and volume with the bone mineral density and the ability to predict vertebral fractures.
