The Department of Nuclear Medicine & Molecular Imaging (PET CT) started in 1996. It was one a major milestone in the development of Ruby Hall Clinic – the first Hospital owned Nuclear Medicine Department, outside Bombay, in the state of Maharashtra. The department was set up to advance Nuclear Medicine – the science of using Nuclear energy for peaceful purpose. Radiopharmaceuticals – chemicals attached to a small amount of radioactive isotope that once administered to the patient are able to specifically localize within organs and/or organ systems, are actively used for disease treatments. The imaging is done with highly sophisticated equipment known as Gamma Camera System. Ruby Hall Clinic has, upgraded its imaging system three times since the inception of the department, and recently has a state of the art, Dual head Gamma camera system.
