About the Seminar: This seminar examines how modern nuclear medicine moves from molecular mechanism to clinical action. Beginning with the biologic logic of tracer uptake, the session will explore how radiopharmaceuticals interact with tissues, how imaging signals emerge from cellular and biochemical processes, and why different tracers answer different diagnostic questions. Building on that foundation, the talk will trace the path from molecular imaging to theranostics, showing how target expression, patient selection, treatment planning, and follow-up can be integrated within a single imaging-therapy framework. It will also address the field’s most important unresolved challenges, including biologic heterogeneity, radiosensitivity, imperfect specificity, dosimetric limitations, and the ongoing search for next-generation tracers that can improve differential diagnosis and guide more precise targeted treatment.

About the Speaker: Prof. Dr. Neşe İlgin Karabacak is a Professor of Nuclear Medicine at Gazi University Faculty of Medicine with over 30 years of clinical and academic experience in the field. A graduate of Hacettepe University Medical School, she completed her Nuclear Medicine specialty training at Gazi University and went on to pursue postdoctoral and PET fellowship training at Johns Hopkins University, later holding additional academic appointments at Johns Hopkins and the National Institutes of Health. Her expertise centers on functional molecular imaging, oncology diagnostics, and targeted radionuclide therapies (Theranostics), with a career that also reflects sustained contributions to academic training and professional education in nuclear medicine. Prof. Karabacak offers a clinically grounded perspective on how molecular findings are translated into meaningful diagnostic and therapeutic strategies.
