About

I. P. Kema is a leading researcher in clinical chemistry and neuroendocrine tumor (NET) diagnostics, with a primary focus on the development and application of radiopharmaceuticals for positron emission tomography (PET) imaging. Their key research areas include the synthesis of carbon-11 labeled tracers, particularly β-[¹¹C]-5-hydroxy-L-tryptophan (5-HTP), and the metabolic characterization of neuroendocrine tumors. Kema’s major contribution is the development of a reliable, remote-controlled synthesis of β-[¹¹C]-5-HTP on a Zymark robotic system, published in 2006. This work enabled precise, reproducible production of a PET tracer that visualizes the specific metabolic activity of NETs, offering a complementary tool to [¹⁸F]FDOPA for staging these tumors. The paper has garnered 21 citations, reflecting its foundational role in advancing NET imaging. Kema’s achievements include pioneering automated radiochemistry protocols that enhance tracer purity and clinical applicability, directly impacting patient management by improving diagnostic accuracy. Their work bridges synthetic chemistry and clinical oncology, providing researchers and clinicians with a robust method for studying serotonin metabolism in cancer.
