Imaging Offers Greater Insight into Epilepsy
Advances in MRI have enabled better understanding for diagnosing epilepsy, while multimodality techniques allow for better information for surgery and post-surgery follow up, according to experts presenting at ECR 2011.The cause of epilepsy, a chronic nuerological disorder, is a mystery, but over the last 30 years, MRI advances have helped physicians determine a large number of underlying causes, particularly for intractable epilepsy, experts said.

Colon Cancer Deaths May Be Prevented With Increased Screenings
Colon cancer, the third-most-lethal form of the disease for both men and women, would continue an almost three-decade decline with increased screening, the American Cancer Society said. The colon cancer rate, which has been dropping “since the mid-1980s,” would also fall if people modify their lifestyles, the Atlanta-based group said in a report. Only about half of the U.S. population aged 50 and older is up-to-date on colon cancer screening, the report said.

Medical Device Approval Plagued by Unhealthy Delays
Europeans have long extolled centralized planning and tolerated large government bureaucracies. But when it comes to approving medical devices, Europe has taken a decidedly decentralized approach — to the great benefit of patients and health care workers. It is an example the United States would do well to follow.
