Biography

Bart de Keizer is a highly skilled radiologist and nuclear medicine physician  affiliated with UMC Utrecht and the Princess Máxima Center for Pediatric Oncology in Utrecht, the Netherlands. He completed his medical degree at UMC Utrecht in 2002, followed by a PhD in Nuclear Medicine in 2004. Dr. de Keizer holds board certifications in both nuclear medicine (2006) and radiology (2015). With over two decades of experience, he plays a pivotal role in imaging departments, combining expertise in both adult and pediatric oncology care. Dr. de Keizer continues to contribute to advancements in medical imaging and treatment. a distinguished researcher in oncology with a specialization in nuclear therapy and diagnostic imaging. His expertise spans a range of cancers, including thyroid cancer, head and neck cancer, and pediatric oncology. 

Research and Publications

Dr. de Keizer's research is dedicated to advancing the diagnostics of oncological diseases. By evaluating current diagnostic scans and introducing new imaging techniques, his work aims to enable image-guided treatments that could increase the cure rates for cancer patients.

In recent years, Dr. de Keizer has been instrumental in the introduction of several new radioactive tracers and PET scans. Notable examples include:

  • Fluor-18-choline PET-CT for detecting parathyroid adenomas
  • Gallium-68-tilmanocept PET-CT for sentinel lymph node detection
  • Fluor-18-MFBG for detecting neuroblastoma
