Dr. Kagen has used novel MRI techniques and coils in the field of prostate MRI in order to improve patient comfort and image quality during prostate MRI examinations. This research has led to improved patient satisfaction for this particular procedure at his institution. In addition, Dr. Kagen used new MRI contrast agents in the assessment of patients undergoing microsurgical reconstruction of the breast, extremities and lymphatic system. He currently works on research aimed at the preoperative and postoperative assessment of patients undergoing vascularized lymph node transfer. He also focuses extensively on diseases of the liver, with special attention to novel molecular imaging agents in MRI which can help provide insight into hepatocellular tumor biology.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Below are financial relationships with industry reported by Dr. Kagen during 2015 and/or 2016. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Industry-Sponsored Lectures: MSSM faculty occasionally give lectures at events sponsored by industry, but only if the events are free of any marketing purpose.
