Teleradiology Offers CT Colonography to Rural Areas

CT colonography, which is a highly effective colorectal screening test, is feasible in rural health centers with the help of teleradiology, according to a study performed at the University of Arizona in Tucson, AZ.

Remote CT colonography (CTC) was performed on 86 patients at two remote medical centers (343 and 337 miles from the University). Technologists at the facilities performed CTC on the patients and the data obtained was then sent to a local teleradiology server where it was uploaded to a CTC workstation and interpreted by an off-site radiologist.

“Out of the 86 patients who had CTC examinations, we obtained 77 technically satisfactory examinations,” said Arnold Friedman, MD, FACR, lead author of the study.

“In many remote health centers there are not enough personnel and resources to use optical colonoscopy as a colorectal cancer screening test. Most centers have CT machines modern enough to do these exams but do not have the resources to perform optical colonoscopy screening. This is an excellent model for rural centers,” said Dr. Friedman.

“Availability of CTC permits access to a robust method of colorectal screening for these rural patients. Using an existing teleradiology network is the most cost efficient way to get the datasets for interpretation,” he said.

This study will be presented at the 2009 ARRS Annual Meeting in Boston, MA, on Tuesday, April 12. For a copy of the full study, please contact Heather Curry via email at

About ARRS

The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
