The University of Oklahoma has received funding from the National Institutes of Health to establish the Oklahoma Center of Medical Imaging for Translational Cancer Research, a collaboration between the Gallogly College of Engineering on the OU Norman campus and OU Health Stephenson Cancer Center in Oklahoma City.
“Great scientific advancements are best achieved through multidisciplinary collaboration, which is exactly what will be accomplished at the Oklahoma Center of Medical Imaging for Translational Cancer Research,” said OU President Joseph Harroz Jr. “This exciting effort unites some of the brightest minds from across two of our campuses, who will combine their expertise to develop life-changing solutions. Their work is a prime example of how OU researchers are reaching beyond traditional boundaries to spark new discoveries with real-world impacts.”
The award from the Centers of Biomedical Research Excellence (COBRE) program of the NIH is expected to provide more than $11.3 million over a five-year Phase 1 period, with the opportunity to compete for renewal for up to three phases. The first phase supports the center’s establishment to galvanize multidisciplinary biomedical research through equipment and facilities support to junior faculty. This is the second COBRE center on OU’s Norman campus, joining the Oklahoma COBRE in Structural Biology.
Bin Zheng, Ph.D., a professor and Oklahoma TSET Cancer Research Scholar in the Gallogly College of Engineering’s School of Electrical and Computer Engineering, is leading the new center.
About the Oklahoma Center of Medical Imaging for Translational Cancer Research
Medical imaging is an essential tool to help doctors and scientists assess the size and scope of a tumor that will be effectively removed by surgery, as well as the rate at which tumors shrink in response to medical interventions such as chemotherapy or radiation therapy. OU researchers are investigating multiple avenues to help improve medical imaging use in cancer detection, diagnosis and treatment.
“Radiological imaging tries to detect a tumor or disease area, while pathologic imaging tries to confirm whether it is benign or malignant,” Zheng said. “While there are other kinds of testing methods, like blood testing, imaging is the most commonly used by clinicians.”
“The problem is that reading medical images by radiologists is quite difficult because tumors, cancer and most diseases are very heterogenous – there is a lot a variation,” he added. “We often see different image diagnostic results from different clinicians or different hospitals because of the large inter-reader variability. This can result in applying different treatment options and potentially reduce treatment efficacy.”
To counter this challenge, the center’s researchers are developing quantitative imaging markers to provide an objective measure or index that can reduce subjectivity and improve consistency for medical image diagnosis using two primary types of research approaches.
The first approach is to develop new investigative cutting-edge imaging modalities to expand ability of doctors to see or detect more detailed tumor internal structures such as using the advanced optical imaging modalities and technology.
The second is to explore and extract more effective image features from the existing clinical imaging modalities – like CT, MRI and X-ray images – and then using artificial intelligence or machine learning models to develop new quantitative imaging markers to help reduce subjectivity and variability of cancer diagnosis and predicting cancer prognosis.
“When some patients undergo cancer treatments, some will respond favorably while others do not. The tumor continues to grow, so if we can develop a quantitative imaging marker to predict a patient’s likelihood to respond to a certain kind of chemotherapy or treatment, we can help physicians explore an alternative approach that may be more effective,” Zheng said.
In each year of Phase 1 of the NIH COBRE program, the center will support two new pilot research projects that can help junior faculty test theories and gain experience before going on to lead independent high-impact research.
The center is beginning with four projects currently underway. Three projects are led by faculty in the Gallogly College of Engineering and one by a clinician scientist at the Stephenson Cancer Center. All four projects will include close collaboration between engineering researchers from the OU Norman campus and clinician scientists from the OU Health Sciences Center campus to promote interdisciplinary and translational cancer research.
