New device uses submarine technology to diagnose stroke quickly
Date:3/29/2011

CHICAGO, Ill. (March 29, 2011)A medical device developed by retired U.S. Navy sonar experts, using submarine technology, is a new paradigm for the detection, diagnosis and monitoring of stroke, says a team of interventional radiologists at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago, Ill. Each type of stroke and brain trauma is detected, identified and located using a simple headset and portable laptop-based console. The device's portability and speed of initial diagnosis (under a couple of minutes) make it appropriate for many uses outside of the hospital setting, including by military doctors in theater who need to assess situations quickly and efficiently in order to provide critically injured troops with treatment.

"We have developed and validated this portable device for the detection of stroke that is based on decades of submarine warfare technology," said Kieran J. Murphy, M.D., FSIR, professor and vice chair, director of research and deputy chief of radiology at the University of Toronto and University Health Network, Toronto, Ontario, Canada. He said this technology could easily differentiate normal brain from life-threatening conditions, such as swelling (hematoma) and bleeding (hemorrhage). "For example, when a physician suspects stroke time is of the essence, doctors could use the system to determine treatment that needs to begin immediately," he added. The device's continuous monitoring capabilityunique in neurodiagnosticswill allow immediate detection of changes in a patient's condition. In addition to its being ideal for field ER, ambulance or military use, the researchers' hope is for the technology to be adapted and used in other areas of acute care, such as open heart surgery (where stroke is an ever-present concern), in other vascular indications elsewhere in the body and in monitoring the progression of disease for drug efficacy.
