Detecting Insulitis in Type 1 Diabetes with Ultrasound Phase-change Contrast Agents

D. G. Ramirez, A. K. Upadhyay, V. T. Pham, M. Ciccaglione, M. A. Borden, R. K. Benninger

This paper demonstrates that ultrasound contrast agents can detect insulitis in pre-symptomatic type 1 diabetes by tracking nanodroplet extravasation into immune-infiltrated islets.
