Overview
Nuclear medicine physicians use radiotracers for functional imaging and deliver radionuclide therapies for oncologic and non oncologic conditions. The specialty combines imaging interpretation with radiopharmacy, dosimetry and radiation safety. Theranostics integrates diagnostic imaging with targeted radionuclide treatment to personalize care.
Clinical Practice
Applications include PET and SPECT imaging for oncology, cardiology and infection and radionuclide therapy for conditions such as neuroendocrine tumors and prostate cancer. Physicians oversee tracer selection, activity dosing and post therapy monitoring and coordinate inpatient isolation when required. Quantitative imaging supports response assessment and dosimetry planning.
Procedures and Tools
Tools include PET/CT PET/MRI SPECT gamma cameras and radiopharmacy facilities for tracer preparation and quality control. Dosimetry, radiation safety protocols and collaboration with medical physics are essential for safe practice. Participation in theranostic programs requires multidisciplinary coordination and regulatory compliance.
Training and Roles
Nuclear medicine physicians complete residency or fellowship training in nuclear medicine or hybrid pathways and maintain certification in imaging and therapy. They work closely with oncology, cardiology and radiopharmacy teams and contribute to tracer development and clinical trials. Ongoing education in radiopharmaceutical advances is critical.
