Dr. Jacob Stephenson is among Kerala’s most experienced nuclear medicine doctors, with deep clinical expertise in molecular imaging, radionuclide therapy, and precision diagnostics for cancer, thyroid, cardiac, bone, and renal conditions. His strength lies in interpreting PET-CT and SPECT scans that detect disease at the earliest cellular stage, and in delivering targeted radioisotope therapies that reach conditions other modalities often cannot.

Over a long career in government medical service, he has held senior academic and clinical positions including Professor and Head of Nuclear Medicine, training generations of doctors and leading complex case management across oncology, endocrinology, and cardiology. Patients across Central Kerala and beyond consult him for accurate early diagnosis, cancer staging and restaging, thyroid evaluation, and personalised radionuclide therapy planning.
