Calgary, AB - New research from the University of Calgary's Faculty of Medicine shows that doctors can make a stroke diagnosis using an iPhone application with the same accuracy as a diagnosis at a medical computer workstation. This technology can be particularly useful in rural medical settings. This allows for real-time access to specialists such as neurologists, regardless of where the physicians and patients are located.
Neuro-radiologists in the study looked at 120 recent consecutive noncontrast computed tomography (NCCT) brain scans and 70 computed tomography angiogram (CTA) head scans that were obtained from the Calgary Stroke Program database. Scans were read by two neuro-radiologists, on a medical diagnostic workstation and on an iPhone. The research is published in the May 6th edition of Journal of Medical Internet Research. The study was designed by Dr. Mayank Goyal, and involved the iPhone software technology originally developed by Dr. Ross Mitchell, PhD, and his team at the Hotchkiss Brain Institute (HBI), then further enhanced and commercialized by Calgary Scientific Inc.
"This iPhone app allows for advanced visualization and our studies show it is between 94% and 100% accurate, compared to a medical workstation, for diagnosing acute stroke," says Mitchell who is from the University of Calgary's Faculty of Medicine. "In a medical emergency, medical imaging plays a critical role in diagnosis and treatment, time is critical in acute stroke care, every minute counts."
Fellow HBI member, Dr. Mayank Goyal who is also the director of research in the department of radiology and one of the neuro-radiologists in the study who analyzed the data. "Time is critical for diagnosing stroke and starting treatment. There are definitely benefits for doctors to have the ability to analyze and diagnose these images from virtually anywhere. We were pleasantly surprised at our ability to detect subtle findings on the CT scan, which ar
