Drawing upon her experience in international radiology, education, and leadership, Dr. DeStigter co-founded a nonprofit organization, Imaging the World, in 2008 that specializes in integrating low-cost ultrasound programs into remote health clinics where radiologists, technologists and the usual infrastructure required of imaging systems are lacking (www.imagingtheworld.org ). Through her work over the last fourteen years, clinical facilities in rural Uganda and Malawi have access to reliable ultrasound imaging, close to home for many patients. The program is supported by grant awards, including from the Bill & Melinda Gates Foundation. In 2016, Dr. DeStigter received the American College of Radiology Foundation Global Humanitarian Award for her work improving medical imaging and access to care. In addition, she received a Certificate of Recognition from the Uganda Society for Advancement of Radiology and Imaging (USOFARI) for providing invaluable resources towards improving breast cancer diagnosis and management in Uganda.
