Dr. Olusegun Ayeni

Olusegun Ayeni is a nuclear medicine physician and academic whose work centers on oncologic and cardiologic molecular imaging, with strong engagement in resource-constrained healthcare settings. Affiliated with institutions in sub-Saharan Africa, his scholarship reflects a commitment to advancing PET/CT and SPECT imaging in regions facing infrastructural and economic limitations.

His research explores the clinical application of FDG PET/CT in lung cancer therapy monitoring, myocardial viability assessment, and cervical cancer staging, alongside investigations into PSMA-based imaging for prostate cancer. Notable contributions include studies on modulated electro-hyperthermia in cervical cancer and the imaging of HIV-associated malignancies, highlighting nuanced interpretation of nodal disease in endemic settings.

Ayeni’s publications also address practical challenges in nuclear medicine, from imaging pitfalls after vaccination to radiation safety and protocol optimization. Collectively, his work demonstrates expertise in translational imaging, therapy response evaluation, and the adaptation of advanced nuclear techniques to improve cancer care and cardiovascular management in low-resource environments.
