Nuclear Medicine and PET

Nuclear medicine department utilizes radio-isotopes in the diagnosis and treatment of diseases. Nuclear medicine techniques are very safe without significant adverse effects. It is utilized in the evaluation of the function of the organs. Nuclear medicine techniques can identify diseases early in their course, even before conventional imaging methods are able to detect the disease.

Positron emission tomography (PET-CT) is indispensable in evaluation of oncology patients. It is also utilized in evaluation of myocardial viability and in evaluation of neurological conditions.

OP Timing
