Portrait of Ahmed Gharib


Dr. Gharib earned his medical degree from the Faculty of Medicine, University of Alexandria, Egypt in 1993. He served as a Chief Resident at the University of Washington, Seattle, WA.  Dr. Gharib is boarded in both Diagnostic Radiology by the American Board of Radiology and in Nuclear Medicine by the American Board of Nuclear Medicine. His fellowships include Chest Radiography (University of Washington), Cross Sectional Imaging (Johns Hopkins University) and Molecular Imaging (NIH).  

Dr. Gharib has been a Staff Radiologist at the NIH since 2005. His clinical interests are in multimodality cardiovascular imaging (including cardiac CT and MR) and body MRI, while his research efforts are focused on early detection of atherosclerotic plaque. Dr. Gharib serves as a primary and associate investigator on several research protocols. His research appointment is in the National Institute of Diabetes Digestive and Kidney Diseases (NIDDK) for his research work as the senior radiologist in the intramural research laboratory of Dr. Roderic Pettigrew, Director, National Institute of Biomedical Imaging and Bioengineering, while also serving as a clinician in the Diagnostic Radiology Department. 

Dr. Gharib currently serves as a referee for multiple major imaging journals including Radiology, the American Journal of Radiology, Investigative Radiology and Magnetic Resonance in Medicine. He has also been an invited speaker at multiple national and international meetings.
