Editor’s E-Note

The window to begin ischemic stroke treatment may remain open a little longer than previously thought, according to research from Massachusetts General Hospital published in the online edition of Radiology. That news would be most excellent. Each hour that the effective treatment window stays open means fewer patients need to rely on being lucky to have the best chance of full recovery.

Several years ago, a young colleague of mine, who was in her 20s at the time, suffered a stroke and had the presence of mind to recognize what might be happening and call her doctor immediately. Her physician promptly dispatched the emergency helicopter, which picked her up at a suburban Philadelphia hospital and airlifted her to a stroke center in Philadelphia—where clot-busting drugs were started within hours. She made a full recovery and expressed marvel about how good timing played such a prominent role in her getting state-of-the art care. This month’s E-News Exclusive discusses findings that may extend the window available to clot-busting drugs to nine hours for some patients.

For more on the topic, a recent Radiology Today article talks about how MRI imaging may help improve stroke prevention by better predicting future adverse events.

And don’t miss our recent article on the changing DR marketplace. As the cost of direct DR systems decreases, CR is losing some of its price advantage. CR cassettes still offer flexibility most direct digital plates don’t, but the market dynamic is changing.

Also, check out the Reuters report on how CT scan dose varies among facilities and equipment. It’s an important story everyone in imaging should read, and it’s located in our “Other Radiology News” section below.

Stroke Treatment Window May Open a Little Wider

Some patients who suffer a stroke as a result of a blockage in an artery in the brain may benefit from a clot-busting drug nine or more hours after the onset of symptoms. The findings were published in the online edition of Radiology. An imaging study analyzing perfusion and diffusion MRI scans suggest that research should be done to see whether the window for treating stroke patients with tissue plasminogen activator (t-PA) could be extended to as long as nine hours—six hours more than current guidelines.

“Stroke is the third leading cause of death in the U.S.,” says the study’s lead author, William A. Copen, MD, director of advanced magnetic resonance neuroimaging at Massachusetts General Hospital in Boston. “Every hour that we can add to the treatment window would allow vastly more stroke patients to be treated with potentially lifesaving therapy.”
