Abstract:
Embodiments describe an accurate and rapid method for assessing spinal bone density on chest or abdominal CT images using post-processed colored images. Post-processing of CT images for the purposes of displaying the spine is followed by color enhancement of routine unenhanced or contrast enhanced CT images to improve diagnostic accuracy, inter-observer agreement, reader confidence and/or time of interpretation as it relates to assessing bone density of the spine. CT images are post-processed (without changes to the standard-of-care CT imaging protocol and without additional cost or radiation for the patient) to straighten the spine for improved visualization of multiple segments. The color-enhanced images can be displayable simultaneously with the grayscale images. Methods and systems are provided for performing opportunistic bone density screening.

Claim (Index 12):
A computer system for opportunistic bone density screening using digital computed tomography (CT) image data, the computer system comprising:\n one or more processors; and one or more computer readable hardware storage devices, wherein the one or more computer readable hardware storage devices comprise computer executable instructions executable by at least one of the one or more processors to cause the computer system to perform at least the following:\n receive, at an image processor, digital CT image data obtained by a digital image capture device, wherein the digital CT image data comprises at least one medical image; \n process the digital CT image data with the image processor to obtain a straightened sagittal image of the midline spine such that processing the digiatal CT image comprises removing a spinal curvature by aligning vertebrae in a co-localized plane; \n identify an attenuation value for one or more pixels in the at least one medical image; \n provide a color palette comprising one or more colors, wherein the one or more colors are each related to a specific range of attenuation values, and wherein each specific range of attenuation values corresponds to one or more different bone density conditions; and \n map the selected color palette to the straightened thick slab sagittal image of the spine to screen for abnormal bone density conditions.
