Freestanding MRI makes cardiac stress testing accessible
For the past 30 years, assessing cardiac health with MRI has been limited to large academic centers -- due to the complexity of the technology and the skill needed to create diagnostic-quality images. This reality has slowed its growth.

Chest CT muscle attenuation predicts future bone density loss
By Will Morton
Muscle and bone loss commonly coexist with aging, but potential links between paraspinal muscle and thoracic vertebral bone mineral density loss remain poorly understood
September 15, 2026
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.
