MRI proves popular at Rio Olympics | Reducing dose for CT lung screening | Last week of Minnies nominations

Dear AuntMinnie Member,

Advanced imaging technology available in the polyclinic at the Olympic Games in Rio de Janeiro is proving popular with athletes, many of whom don't have access to such technology in their home countries, according to a new article we're featuring in our MRI Community.

Eye exams, dental x-rays, and MRI scans "are being doled out by the thousands," according to reports from the polyclinic, with around 60 MRI scans being performed each day on the facility's two scanners. Read more about how imaging is playing a role at the Olympics by clicking here.

While you're in the MRI Community, be sure to read a new article on a start-up company that has developed a novel MR-based test for detecting signs of sepsis in patients. While the system doesn't produce images, it uses the principles of diffusion-tensor MRI to analyze blood samples quickly for signs of pathogens.

Reducing dose for CT lung screening

Researchers and CT vendors are successfully leveraging technologies such as iterative reconstruction to drive CT radiation dose to ever-lower levels. But oftentimes these images are noisy and difficult to read. Can image processing help?

Researchers from the U.S., France, and Switzerland sought to answer this question by applying different techniques to images they produced at what they call "microdose" radiation levels -- in the range of 0.1 mSv. They processed the images with both computer-aided detection algorithms and maximum intensity projection techniques to see which was most effective in helping radiologists find cancer.
