Virtual colonoscopy can help patients avoid conventional colonoscopy

01.12.2004


The significance of a detected colon polyp matches closely with the confidence score of an interpreting radiologist using virtual colonoscopy. This suggests that virtual colonoscopy may help determine if polyp removal is truly needed, thereby avoiding overuse of invasive conventional colonoscopy, according to a new study in the December 2004 issue of the American Journal of Roentgenology.



Virtual colonoscopy is a relatively noninvasive examination that uses a CT scan to evaluate the colon for polyps. "Among the benefits of virtual colonoscopy are that, unlike conventional colonoscopy, the procedure does not require intravenous pain medications, sedation or recovery room time," said Perry J. Pickhardt, MD, from the University of Wisconsin Medical School and lead author on the paper.

For the study, 1,339 patients with no symptoms underwent both virtual colonoscopy and conventional colonoscopy. A total of 305 polyps were found at virtual colonoscopy that were 6 mm or larger, the size at which the physician needs to decide how to treat the patient. For those polyps, the likelihood that the polyp was found at conventional colonoscopy and that it was potentially precancerous correlated closely with the confidence score of the interpreting radiologist.


"Although conventional colonoscopy is an excellent test, it does carry a small but real risk for significant complications. While this risk is acceptable for patients with large polyps, it may outweigh the potential benefit for patients without large polyps, which comprise the vast majority of the asymptomatic screening population. In short, it seems prudent to reserve this more invasive procedure for those patients with a higher likelihood for harboring a significant polyp," said Dr. Pickhardt.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
