Artificial Intelligence (AI) in Nuclear Medicine

The field of nuclear medicine harmonises technologies in diagnostics and therapeutics through the use of radiopharmaceuticals. The quantification of radioactivity detected from and delivered to a patient’s body and/or tumours in the patient requires highly precise modelling and calculations, much of which can be time consuming and computationally demanding. The field of nuclear medicine employs a myriad of computational models and algorithms in reconstruction images from Positron Emission Tomography (PET) scans and also in the planning for dosimetry in radionuclide therapeutic procedures. Artificial Intelligence (AI) supplements these computational algorithms and can reduce processing time. Doctors and allied health professionals within DNMMI participates in both imaging-related and non-imaging related AI research as part of overall research efforts under the Division of Radiological Sciences. We have also curate rich clinical and imaging databases pertaining to radionuclide theranostics and PET imaging.
