Optoacoustic Imaging Reveals Scope of Pancreatic Cancer at Early Stage
OKLAHOMA CITY, Feb. 8, 2024 — A new imaging technique could improve survival rates for pancreatic cancer by enabling physicians to detect the full extent of the disease in its early stages. The technique pairs a contrast agent with multispectral optoacoustic tomography (MSOT) to identify pancreatic cancer cells at the microscopic level, at approximately 10 times more magnitude than what is currently possible. The research is led by professor Lacey McNally and professor Ajay Jain, MD, at the University of
