The new method uses analytics technology developed by the Mayo and IBM collaboration, Medical Imaging Informatics Innovation Center and has proven a 95 percent accuracy rate in detecting aneurysms, compared with 70 percent for manual interpretation. Project findings were reported in the Journal of Digital Imaging (published online Nov. 24, 2009).
Already saving patients’ lives, the project has examined more than 15 million images from thousands of patients since the project began in early July. It uses technology that combines advanced imaging with analytics to highlight likely aneurysms for faster detection. This helps radiologists identify them before they result in brain hemorrhage or neurological damage. In the future, Mayo Clinic expects to use the same approach for other radiology detection tests such as the diagnosis of cancer or vessel anomalies in other parts of the body.
“This fully automatic scheme is significant in helping radiologists detect aneurysms in magnetic resonance angiography exams,” says Mayo radiologist Bradley Erickson, M.D., senior author of the study and co-director of the Medical Imaging Informatics Innovation Center at Mayo Clinic.
One out of 50 people in the United States has an unruptured brain aneurysm -- an abnormal outward bulging in the blood vessels in the brain -- and about 40 percent of all people who have a ruptured brain aneurysm will die as a result.
Traditionally, a patient suspected of having a brain aneurysm due to a stroke, traumatic injury or family history would undergo an invasive test using a catheter that injects dye into the body, a technique with risks of neurologic complications. To improve the process of detection using noninvasive magnetic resonance angiography imaging technology, Mayo Clinic and IBM worked to create so-called “automatic reads” that run detection algorithms immediately following a scan.
Once images are acquired, they are automatically routed to servers in the Mayo and IBM Medical Imaging Informatics Innovation Center located on the Mayo campus in Rochester, a collaborative research facility that combines advanced computing and image processing to provide faster, more accurate image analysis. There algorithms align and analyze images to locate and mark potential aneurysms -- even very small ones less than 5mm -- so specially trained radiologists can conduct a further and final analysis.
From the time an image is taken to the time it is ready to be read by a radiologist, there often is only a 10-minute window. In that 10 minutes, the new workflow is able to identify images coming off of the scanners and route those related to the head and brain through the special workflow which then conducts automated aneurysm detection. On average, this can be done in three to five minutes, improving efficiency and saving valuable radiologist’s time, leading to a quicker diagnosis which is especially important in the case of a serious aneurysm.
“Our joint work with Mayo Clinic on this project taps IBM’s deep expertise in high performance computing and applies it to health analytics, enabling us to remove some of the time and efficiency barriers and making imaging an even more valuable preventative screening tool. Enabling broad access to this capability via cloud delivery is the natural next step,” said Bill Rapp, IBM's CTO of Healthcare and Life Sciences and co-director of the Medical Imaging Informatics Innovation Center.
The aneurysm detection system uses an algorithm developed by Mayo researchers that is executed on IBM WebSphere Process Server to model and orchestrate the automated workflow. Images are stored on IBM DB2 for Linux and Windows data service and workflow logic is run on IBM System x servers and IBM storage.About IBM

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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...
