Currently, radiologists measure the sizes of potentially cancerous lung nodules by measuring their largest widths using a two-dimensional computer screen. (The method widely used to do this is called RECIST.) Now, researchers are investigating volumetrics, by which they can measure nodules in 3D.
Thanks to work done by a team of researchers at the National Institute of Standards and Technology (NIST), in the simplest of cancer cases, volumetrics appears to reveal volume changes far more precisely than currently possible on 2D screens, which could cut diagnosis time from six months down to four weeks, the researchers estimate.
"We found … Read more
