Nuclear Medicine Imaging

Nuclear medicine imaging is a multidisciplinary speciality that combines medicine, physics and chemistry to assess physiological function at a molecular level. Using techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT), clinicians administer radiopharmaceuticals that localise within specific tissues and emit detectable radiation. This enables visualisation of metabolic and biochemical activity rather than anatomy alone. By revealing functional change, nuclear imaging supports early disease detection, treatment planning and response assessment, particularly in oncology, cardiology and neurology. Certain radiopharmaceuticals also deliver targeted therapeutic radiation, selectively treating malignant tissue while limiting exposure to healthy structures. Through its diagnostic and therapeutic capabilities, nuclear medicine remains central to precision medicine and personalised patient care.
