University of Central Florida professor Mubarak Shah is applying the techniques used to detect suspicious activity in airports, stadiums, and other public places to find and measure potentially life-threatening brain tumors. Shah, Orlando Health System neuro-oncologist Dr. Nicholas Avgeropoulos, and Florida Hospital Zephyrhills Sunshine Radiology neuroradiologist Dr. David Rippe are developing a method that will automatically measure and compare the size of a tumor in three dimensions from MRI scans. "Radiologists use computers to look at scans, but this is taking the next step — allowing computers to help radiologists analyze the pictures and enabling an automated method to calculate the size of tumors," Rippe says.
A radiologist's analysis can be limited by a variety of factors, including tumors that are irregular in shape or have jagged edges, tumors with liquefied centers, or surrounding tissue that is deformed or changing shape — all of which are difficult to see and quantify. The automated analysis of a small data set using a preliminary method from Shah has proven to be up to 90 percent accurate compared to analyses by radiologists.
