Advanced Machines that aid Cardiac Imaging. Nuclear Medicine has got a tremendous role in cardiac imaging. In fact, it is complementary to coronary angiography to the assessment of haemodynamically significant lesions which is helpful in the therapeutic decision making. The Department of Nuclear Medicine is equipped with advance state-of-the-art Siemens Symbia Dual Head SPECT Gamma Camera as well as GE-Discovery 530C (Latest solid state detector technology). Nuclear medicine use small doses of radioactive material to assess myocardial blood flow, evaluate the pumping function of the heart as well as visualisation of location of a heart attack.
