Dr. Pucar is an Assistant Professor of Radiology, a member of the Head and Neck Tumor Board, and a nuclear radiologist with special interest and training in oncologic imaging. Dr. Pucar earned an M.D. degree from University of Belgrade, Serbia and Ph.D. degree in Molecular Pharmacology and Experimental Therapeutics from Mayo Graduate School, Rochester, Minnesota. Dr. Pucar completed a Radiology Residency at New York Presbyterian Hospital and a Nuclear Medicine Residency and Molecular Imaging Fellowship at Memorial Sloan Kettering Cancer Center (MSKCC), Cornell University, New York, New York.
Dr. Pucar has clinical and research interests in cancer staging, restaging, and prognostication, particularly of head and neck, lung, prostate, and gynecological cancers, and lymphoma. He is assessing a correlation of various imaging modalities (PET/CT, CT, MRI) and pathology in order to improve a diagnostic accuracy of imaging. Dr. Pucar is interested in developing imaging biomarkers, particularly using PET/CT, developing nomograms based on clinical and imaging parameters for staging, outcome prediction and treatment selection in the individual patients (personalized medicine), incorporating imaging in NCCN guidelines, and implementing quantitative and computer-assisted imaging. Dr. Pucar is currently assessing a utility of PET/CT and CT in staging of oral cavity and lung cancers using surgical pathology as a gold standard. Ongoing parathyroid imaging projects are aimed to facilitate minimally invasive parathyroid surgery. Dr. Pucar is working on implementation of the integrated oncologic database, CAISIS, at GHSU based on his MSKCC experience. Dr. Pucar is also planning to continue prostate cancer imaging research that he had been conducting at MSKCC, including clinical imaging and basic science research on the role of the PI3 kinase pathway in the pathogenesis of prostate cancer.
