Congratulations to QIAL’s Dr. Alexandra Badea and Dr. Trong-Kha Truong on receiving the 2025 Medical Physics Fall Seed Grant Award for their project, “Predictive Modeling of Alzheimer’s Disease Risk Using Explainable AI and High-Resolution MRI.”

Delighted to host Dr. Kristina Bliznakova, Fulbright Scholar, at Duke’s Quantitative Imaging & Analysis Lab. Looking forward to teaming up on photon-counting CT and virtual  imaging.

Our team developed anatomically variable digital Wistar rat phantoms for realistic preclinical imaging simulations, enabling PCCT studies & reducing animal use. Segars, H. E., Nadkarni, R., Badea, C. T., Badea, A., Chin, B., Johnson, G. A., Payne, J., Samei, E., … Continue reading →

Our QIAL lab member Rohan Nadkarni brought the heat at the BME retreat—taking 2nd place in the rapid-fire challenge with original rap lyrics

Congratulations! Dr. Hae Sol Moon has successfully defended his PhD on “Integrative Modeling of Alzheimer’s Disease Risk”.

Huge congratulations to Dr. Alex Allphin on a successful PhD defense! A key member of our QIAL lab, Alex’s work has pushed the boundaries of imaging science.

Voluntary & enforced exercise drive distinct brain changes in Alzheimer’s models.MRI reveals how emotion, memory, & motor circuits adapt—showing exercise’s neuroprotective power.

This study investigates the impact of exercise on cardiac function across different APOE genotypes in mice using low-dose cardiac photon-counting micro-CT and deep learning-based segmentation. Results show significant, genotype-dependent improvements in cardiac performance, with the largest effects observed in APOE3 … Continue reading →
