Diana Tourassi’s Background and Early Interest in Math

From an early age, Diana Tourassi had a passion for learning and a fascination with science and mathematics. Growing up in Greece, she was always solving complex problems and conducting experiments, setting her apart from others in her traditional environment.

Diana Tourassi’s Background and Early Interest in Math

Tourassi’s interest in mathematics and science started at a young age. She excelled in math and science courses, fueled by an innate curiosity about how things work. Her favorite subjects were geometry, algebra, and physics. Solving logic problems and brain teasers were a fun pastime.

Tourassi went on to earn a degree in Electrical Engineering from the National Technical University of Athens, one of the top universities in Greece. She developed a keen interest in medical imaging, using engineering concepts to help diagnose and treat diseases. The possibility of combining math, science and medicine to help people in this way inspired her career path.

After earning her PhD in Biomedical Engineering and Medical Physics from the University of Patras in Greece, Tourassi moved to the U.S. for a research fellowship at Duke University. There, she worked on computer-aided diagnosis systems using machine learning algorithms. Her research focused on the use of medical imaging and artificial intelligence for the early detection of breast cancer.

Tourassi went on to become a pioneer in the field of radiology and medical image perception. Her innovative research has led to breakthroughs in computer-aided diagnosis and quantitative image analysis that have the potential to save lives. Through passion and perseverance, Diana Tourassi achieved her childhood dream of using science and mathematics to help others in a meaningful way.

Pioneering Work at Oak Ridge National Laboratory

As a pioneer in medical imaging research, Diana Tourassi accomplished groundbreaking work during her time at Oak Ridge National Laboratory (ORNL). Established in 1943, ORNL operated the first nuclear reactor and became a leader in nuclear research.

Tourassi joined ORNL in 2000 as a scientist focused on improving breast cancer detection using digital mammography. She developed computer algorithms to better analyze mammogram images and detect abnormalities. Her work led to earlier detection of breast cancer and reduced false positives.

Improving Lung Cancer Screening

Tourassi then turned her attention to improving lung cancer screening with low-dose CT scans. Lung cancer is the leading cause of cancer death, in part because it’s often detected at an advanced stage. Tourassi created software tools and artificial intelligence to better analyze lung CT scans and detect lung nodules, enabling radiologists to diagnose lung cancer earlier when treatment is most effective.

Tourassi has also researched quantitative imaging biomarkers to measure the effectiveness of cancer treatments. By analyzing CT and PET scans, she developed non-invasive ways to detect how well tumors are responding to therapies so doctors can quickly modify or switch treatments.

Through innovative research and a passion for using technology to advance medical imaging, Diana Tourassi has made valuable contributions that have and will continue to help in the fight against cancer and improve patient outcomes. Her pioneering work at ORNL has saved and will save many lives.

Research on CAD and Medical Image Analysis at Duke

Diana Tourassi, the associate dean of research at Duke University School of Medicine, is leading pioneering work in medical imaging and image analysis. Her research team at Duke’s Multi-Dimensional Imaging Lab is focused on developing and applying artificial intelligence and machine learning techniques to improve disease diagnosis and prognosis using non-invasive imaging.

Research on Coronary Artery Disease

One study compared two approaches for diagnosing coronary artery disease (CAD) using cardiac CT scans. The traditional method relies on measuring the amount of calcium buildup in the arteries. Tourassi’s team developed a risk analysis model that also considers a patient’s clinical risk factors like high blood pressure or diabetes in addition to the calcium score. They found the risk analysis approach was better at determining who needed further testing or treatment. This could help reduce unnecessary procedures and costs.

Tourassi’s lab is also using machine learning algorithms to analyze cardiac MRI and CT scans. The AI systems can detect specific features of CAD like narrowing or blockages in the arteries. The more data the algorithms review, the better they get at accurately identifying signs of CAD. The goal is for AI to become a ‘second set of expert eyes’ to help radiologists evaluate scans more efficiently and catch diseases earlier.

A Promising Future

Tourassi believes AI and machine learning will revolutionize medical imaging in the coming decades. Her team is working to build large datasets of medical images coupled with patient outcomes and risk factors to further improve AI diagnostics. They also aim to apply similar techniques using MRI and CT scans to detect other diseases like cancer, Alzheimer’s, and liver disease. With Diana Tourassi leading the way, Duke is poised to be a leader in AI for healthcare imaging and make a huge impact on how doctors are able to prevent, detect, and treat disease.

Advancing Radiology With AI and Machine Learning

As a pioneer in radiology, Diana Tourassi has been instrumental in advancing the field through artificial intelligence and machine learning. AI methods are ideal for analyzing the huge amounts of data produced by medical imaging. They excel at recognizing complex patterns and providing quantitative assessments of radiographic images.

Tourassi was quick to realize AI’s potential. According to surveys, AI adoption in radiology skyrocketed from zero to 30% between 2015 to 2020. Tourassi has focused her research on developing AI systems for diagnostic radiology. Her work has explored using machine learning to detect fractures, pneumothoraces, classify thyroid nodules, and diagnose lung diseases.

One of Tourassi’s most promising projects uses AI to analyze chest CT scans and detect lung diseases. The system can detect common diseases like pneumonia, tuberculosis, and lung cancer with a high degree of accuracy. It does this by identifying visual patterns in the scans associated with different conditions. The AI analyzes hundreds of CT slices to determine the likelihood of disease. It can even detect diseases that radiologists sometimes miss.

Tourassi’s research has the potential to greatly improve radiology. AI systems can take over routine tasks like measurements and annotations, freeing up radiologists to focus on more complex cases. They may also provide a “second opinion” to help reduce errors and ensure the most accurate diagnoses. While AI will not replace radiologists, it will transform the way they work. Radiologists who embrace AI have the opportunity to improve workflow, enhance diagnostic skills, and achieve better outcomes for patients.

Tourassi’s pioneering work at the intersection of radiology and AI will have a lasting impact on medical imaging. She has helped establish AI as a vital tool for improving accuracy, efficiency and patient care. Through her research and leadership, radiology has entered an exciting new era of enhanced diagnostics powered by artificial intelligence.
