Dear AuntMinnie Insider,
Translucency rendering software has been promoted as a solution to the problem of lumpy, bumpy 3D endoluminal views that can complicate virtual colonoscopy interpretation. Sussing out true polyps from fecal residue can be tricky, time-consuming -- and requires a lot of jumping back to 2D for confirmation.
The software works by painting different Hounsfield unit values in a rainbow of colors, making it easier to detect the heterogeneous textures that often characterize residual fecal material. Can it boost accuracy? A new study from Italy says yes, though others consider it more of a time-saver than a lifesaver.
Find out what researchers from the University of Rome "La Sapienza" had to say about the matter in this issue's Insider Exclusive story, brought to you in colorful 2D before anyone else can access it.
Also in this issue: the economics of virtual colonoscopy. Dr. Perry Pickhardt, in cooperation with European researchers, leads off with a sophisticated model comparing the cost-effectiveness of colon screening exams, and concludes that VC is by far the most cost-effective method. Meanwhile, a new Danish study says VC can be as cost-effective as colonoscopy with the right workflow and equipment.
Finally, U.S. legislators on both sides of the aisle are teaming up in a bid to restore full funding for approved colon screening exams, which has fallen by as much as one-third since 1998. Look for all this and more in your Virtual Colonoscopy Digital Community.
