About me

Nadine Mallak, M.D. is a double boarded Associate Professor of Diagnostic Radiology at OHSU, in the divisions of Body Imaging, and Molecular Imaging & Therapy. She received her M.D. degree from Saint Joseph University Medical School in Beirut, Lebanon, followed by a Diagnostic Radiology residency at Hotel Dieu de France, Beirut. Subsequently, she finished fellowships in Neuroradiology and Abdominal Imaging, and a residency in Nuclear Medicine at the University of Iowa Hospitals and Clinics.

Dr. Mallak is the clinical director of the PET/MRI program at OHSU. The scope of her clinical practice encompasses all aspects of molecular imaging and therapy, in addition to abdominal and pelvic imaging with modalities including ultrasound, CT, and MRI. Her research interests focus on molecular and hybrid imaging, particularly for prostate cancer, neuroendocrine tumors and pheochromocytoma/paraganglioma. In addition to her research projects, she’s passionate about education. She was voted by the radiology residents "outstanding teacher of the year" for the year 2019-2020, and by the graduating senior residents “outstanding board reviewer” for the year 2021-2022.

In her free time, she enjoys painting, mostly with acrylic and watercolors, reading, hiking, and exploring the gorgeous nature in the Pacific Northwest.
