Nonlinear Image Blending for Dual-Energy MDCT of the Abdomen: Can Image Quality Be Preserved If the Contrast Medium Dose Is Reduced?

This research investigates whether image quality can be maintained in dual-energy multidetector CT (MDCT) of the abdomen when using a nonlinear image blending technique with reduced contrast medium doses. The study compares this approach with traditional 120-kVp linear blending methods to determine if diagnostic quality can be preserved while reducing patient exposure to contrast agents.

The work addresses an important clinical question in radiology by exploring techniques that could potentially reduce contrast medium doses without compromising diagnostic image quality. This has significant implications for patient safety and clinical practice, particularly for patients at risk for contrast-induced nephropathy or other adverse reactions to contrast agents.

The research was part of a consulting collaboration with researchers from Duke University while I was a PhD student at NCSU. It demonstrates the application of advanced imaging techniques and statistical analysis to solve real-world clinical problems in medical imaging, contributing to the ongoing efforts to optimize CT protocols for improved patient care.
