Perceptive Informatics and University of Chicago Collaborate to Bring Breakthrough Imaging Method to Clinical Research

BOSTON, May 29 /PRNewswire-FirstCall/ -- Perceptive Informatics, the technology subsidiary of PAREXEL International Corporation , today announced the availability of a unique medical imaging capability, called the Double Reference Tissue Method (DRTM). Based upon magnetic resonance imaging (MRI), this technique helps to evaluate blood flow to tumors with increased precision. Certain compounds in clinical development to treat cancer have as their mechanism of action the ability to decrease blood supply to tumors. The Double Reference Tissue Method was developed by the University of Chicago and is being commercialized by Perceptive Informatics for the first uses by the bio/pharmaceutical industry in clinical development programs.

“This breakthrough medical imaging method will enable our clients, to make earlier and more informed decisions about their oncology studies,” said Jay Zimmerman, Vice President of Medical Imaging at Perceptive Informatics. “We value our collaboration with the University of Chicago, which represents the innovation that can be achieved when academic institutions and industry technology providers collaborate toward important advances.”

“DRTM will mean significant progress for clinical research since it produces higher quality data for greater visibility into drug activity,” said Dr. Cheng Yang, Professor in the Department of Medicine at the University of Chicago. “We are pleased that this new imaging method now has broader availability and benefit to the biopharmaceutical industry.”

The Double Reference Tissue Method is part of Perceptive Informatics’ portfolio of imaging techniques, used from early development through peri- approval studies. Perceptive’s Medical Imaging division has expertise in multiple therapeutic areas, as well as significant experience in the use of a wide range of imaging modalities including conventional radiography, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, angiography, and nuclear medicine including FDG PET (fluorodeoxyglucose positron emission tomography.
