Raman spec reveals bone strength

Laser imaging may provide a more accurate means for estimating the risk of bone fracture than traditional x-ray measurements of bone mass, according to new research.

Investigators at the Imperial College London tested a Raman spectroscopic technique that allows them to eliminate the spectral components of overlying tissues to measure the collagen that also affects bone strength.

"Traditionally, the only way to predict bone strength has been through x-rays, but these can only measure part of the strength of the bone," noted lead researcher Edward Draper in an Imperial College press release. "Using this new technique, we can get a more complete measurement, allowing us to predict better the risk of fractures as a result of osteoporosis."

The scientists plan to develop their work into a test for women during adolescence to predict the likelihood of osteoporosis developing in later life.

Can AI help chest DDR achieve clinical adoption?

Chest dynamic digital radiography (DDR) may have received a boost toward clinical use in patients with lung disorders, with researchers developing AI to perform time-consuming analysis involved in the technology.

(c) Training data is generated through manually labeling using SLEAP’s graphical user interface. (d-e) Neural network detection schematic. For each quadrant a series of two networks were used. The first identifies the quadrant center, the second using input of the first, then identifies individual anatomical landmarks within a quadrant. (d) Four neural networks were trained, each with the objective of identifying a chest quadrant centroid. The four separate quadrants are visualized as colored boxes (right upper quadrant, green; right lower quadrant, blue; left upper quadrant, red; left lower quadrant, yellow). (e) Serial centroid then anatomical identification. Two quadrant examples showing confidence maps of trained neural networks identifying quadrant centroids (left) and then anatomical confidence maps (right).
