Nuclear Medicine

Nuclear Medicine is a branch of diagnostic imaging that uses trace amounts of radioactive pharmaceuticals to map the function of many organs and body systems. Common areas are the heart, bones, lungs, kidneys, liver, stomach and thyroid gland.

The tracer, usually injected into an arm vein, concentrates in the area of interest. A gamma camera moves close over the area, building an image from the radiation emitted. A complex digital system then analyses, stores and displays the images that are evaluated by our medical imaging specialists.

Nuclear Medicine can provide a rapid and accurate diagnosis of a wide range of medical conditions when used alone or in conjunction with other imaging tests.

All Lake Imaging nuclear medicine technologists are accredited with the Australian and New Zealand Society of Nuclear Medicine (ANZSNM) and registered with the Medical Radiation Practice Board of Australia.
