Keywords: Tumor Imaging, Contrast Agents, Cancer imaging, MR imaging, Radiology I am interested in and involved with novel approaches for Tumor MR Imaging, with an emphasis on the development and evaluation of cell-specific contrast agents. For example, I have utilized superparamagnetic iron oxide nanoparticles (USPIO's) to visualize tumor associated macrophages (TAMs). TAMs are of importance because they correlate strongly with poor outcome in patients with breast cancer and other cancers b..

Dr. Ertosun graduated from Bilkent Üniversitesi (Bilkent University) with a B.S. degree in Electrical & Electronics Engineering in 2004. During his undergraduate studies at Bilkent, he conducted research with Prof. Haldun Ozaktas in the fields of optics and signal processing. He received an M.S. degree in Electrical Engineering from Stanford University in 2006, where his research focused on optoelectronic & semiconductor devices, and carbon nanotubes. He received a second M.S. degree in Financ..

Evaluation of novel PET detectors based on semiconductor photodetectors, Design and development of hardware for MR compatible PET system, Image correction methods for PET images.

My research is focused on developing and evaluating molecular imaging agents for visualizing neurological diseases in living subjects.

My research interest focuses on cellular imaging and MR imaging. My current projects involve evaluations of a FDA approved iron oxide contrast agent, ferumoxytol, for in vivo tracking of stem cell transplants and immune cells. The goal of these cellular imaging techniques is to non-invasively monitor stem cell mediated tissue regeneration and related immune rejection processes. Keeping the translational potential of this agent in mind, we ultimately aim to translate these novel technologies to ..

Developing novel medical devices (based on optical, ultrasound and photoacoustic technologies) and integrating them with clinically relevant molecular imaging strategies to improve the current standards in cancer/disease screening and management.
