ITN Editor Dave Fornell and Mahadevappa Mahesh, Ph.D., chief of medical physicist and professor of radiology and medical physics, Johns Hopkins University. He presented a late-breaking RSNA study on how medical imaging radiation dose has started to drop over the past decade. Watch a VIDEO interview with Mahesh. He is the co-chair of the National Council on Radiation Protection and Measures Report (NCRP), and presented the most recent NCRP data analysis at the 2019 Radiological Society of North America (RSNA) meeting. CT dose dropped about 6 percent, despite a 20 percent increase CT scans since 2006. There was a drop of more than 50 percent for nuclear imaging scans, mainly due to fewer procedures begin performed. There was a 15-20 percent decrease across X-ray imaging modalities. Mahesh says this shows the impact of using ALARA principals, new dose guidelines and programs like Image Wisely and the ACR Dose Index Registry.

This is an artificial intelligence (AI) of a reconstructed image of lung bronchia in one image, demonstrated by the vendor Vida in its LungPrint software. Rather than needing to follow each branch on the slice the CT study. The purpose is to offer a quick view of the airways and help quickly identify any issues. This Hyperion view is also used as a reference image when the AI identifies anything in the scan, such as suspected nodules, COPD or emphysema. 

The AI also can automatically fetch and compare prior images. It detects and color coded areas of high and low density.

The company has signed agreements to have its software available through the AI marketplaces offered by TeraRecon, IBM Watson, Blackford and Nuance.
