He wrote or co-wrote more than 120 peer-reviewed scientific articles, has written more than 30 book chapters, and served as co-editor of three textbooks. Madoff also served as Deputy Editor for two of the world’s leading imaging journals, Radiology and the Journal of Vascular and Interventional Radiology.

“As a practicing Interventional Radiologist, I believe it’s important to make sure that the credentialing procedures and the technologists themselves are up to date with the latest interventional radiology techniques,” Madoff says. “Credentialing by ARRT is an effective method of increasing technologists’ education in terms of interventional radiology training and awareness. By working with ARRT’s Board, I feel I’ll be one of the liaisons to getting that accomplished.”
