Nuclear Medicine is a branch of medicine in which radioactive materials are used for the diagnosis and treatment of disease. It uses small amounts of radioactive materials, known as radiopharmaceuticals, for diagnostic, therapeutic, and research purposes. Once injected into a patient these radiopharmaceuticals localize in the area of interest, which is then imaged using special machines. Nuclear Medicine provides information about function of nearly every human organ. Patients experience little or no discomfort and do not require anesthesia. Exposure to radioactivity is monitored closely, and kept well below safety limits. The radiation exposure is usually as much as or often lower than the exposure produced by a similar radiological study such as CT. |

GE Discovery IQ PET CT (16 slice) with 5 ring detectors : This is a “state of art” PET CT machine capable of completing a scan in less than 10 minutes, using lesser dose of radioactivity, thereby further reducing the radiation exposure to the patient. |

What is Nuclear Medicine?
|
Nuclear Medicine is a medical specialty that is used to diagnose and treat diseases in a safe and painless way. Nuclear medicine procedures often identify abnormalities at a very early stage of disease. The early detection allows a disease to be treated sooner, when the probability of cure is better. |
| |
| How is nuclear medicine different from X-Ray, CT SCAN ,Ultrasound, or MRI ? |
Nuclear medicine can detect the radiation coming from inside a patient's body. X-RAY, CT scan and USG expose the patient to radiation from outside the body using machines that send radiation through the body. As a result, nuclear medicine determines the cause of a medical problem based on organ function in contrast to the other diagnostic tests, which determine the presence of disease based on anatomy or structural appearance.

| |
Is radioactivity harmful? |
Although exposure to the radioactivity in very large doses can be harmful, the radioactivity in radiopharmaceuticals is well within the prescribed limits of safety. The doses of radiotracer administered are small and diagnostic nuclear medicine procedures result in minimal radiation exposure. Thus, the radiation risk is very low compared with the potential benefits. |
| |
Can nuclear medicine treat disease?
|
| Yes. Every year thousands of patient with hyperthyroidism are treated using radioactive iodine. It can also be used to treat certain kinds of cancers (thyroid,pheochromocytoma) and be helpful in bone pain palliation in cases of osteoblastically active skeletal metastases. |
| |
| Can I have nuclear medicine procedures performed more than once? |
| Absolutely, patients can undergo several scans as part of their medical evaluation. Your doctor will help you decide what is right for you. |
| |
| Can a nursing mother continue to nurse her baby after a nuclear medicine procedure? |
It is best to stop breastfeeding your baby for anywhere from a few hours to a few days after your nuclear medicine study. For many therapy procedures, nursing may have to stop completely. This depends on what kind of study you are having and the radiopharmaceutical that will be used. Your doctor will give you the best advice. |
| |
Do I need to do anything special after I have a nuclear medicine procedure ?
|
After most nuclear medicine procedures,it is generally best to drink a lot of fluids and urinate as frequently as you can .This helps to flush the remaining radioactivity out of your body. |
