The Body Image exhibition, now showing at the University of New South Wales, features artwork exploring the human body by combining medical imaging and animation software.

An evaluation of the impact of computer-aided detection (CAD) systems on interpreting digital mammograms found that radiologists rarely changed their diagnostic decisions after adding CAD, according to results published in the October issue of the American Journal of Roentgenology.

In normal practice, radiologists don’t get do-overs, which is why it’s imperative to get the diagnosis correct the first time. A recently published retrospective review of CT lung cancer screening images showed how cancers can be missed, and underscored the importance of advanced image processing techniques for early detection.

Lung cancers discovered on annual repeat screenings were often identified in the previous round of screening, which suggests the incorporation of advanced image-processing techniques and additional display methods could boost early detection, according to a study published online in American Journal of Roentgenology.

Last month, the Centers for Medicare & Medicaid Services proposed approving Medicare coverage of a stool DNA colorectal cancer screening test. The move had the American College of Radiology asking, “What about CT colonography?”

In a letter to the Centers for Medicare & Medicaid Services, the American College of Radiology (ACR) called for the same coverage criteria to be applied to virtual colonoscopy, or CT colonography, that was used to approve Medicare coverage of a stool DNA colorectal cancer screening test.

The potential for 3D printing in medicine has created quite the buzz, as surgeons, radiologists and others experiment with ways the technology can improve care. While 3D printing applications in medicine are still developing, one inventor is already looking ahead at the next innovation: 4D printing.

A Norwegian study of screening with one-time flexible sigmoidoscopy demonstrated a drop in the colorectal cancer incidence rate by 20 percent and the death rate by 27 percent.
