Chicago—Computed tomography (CT) scanning is becoming the preferred method for detecting certain cancers, but interpretation is time consuming and not infallible. Researchers are creating computer-aided diagnosis (CAD) software that they hope will reduce radiologists' work hours while improving their accuracy when assessing CT images.
CAD software is already used with mammography to detect breast cancer. At the November Scientific Assembly of the Radiological Society of North America (RSNA), researchers presented preliminary findings showing that CAD enhanced CT scanning in detecting colorectal and lung cancers.
To find potentially cancerous polyps, radiologists are using CT colonography that digitally creates three-dimensional images, enabling the viewer to "fly through" the colon to detect troubled areas in a noninvasive manner. But such scanning creates hundreds of images that are time-consuming to study accurately.
