Nuclear Medicine

What is Nuclear Medicine?

Nuclear Medicine uses very small amounts of radioactive materials 

(radiopharmaceuticals) to diagnose and treat disease.

In imaging, the radiopharmaceuticals are detected by special types of cameras that 

work with computers to provide very precise pictures about the area of the body being 

imaged.

In treatment, the radiopharmaceuticals go directly to the organ being treated. 

The amount of radiation in a typical nuclear imaging procedure is comparable with 

that received during a diagnostic x-ray, and the amount received in a typical treatment 

procedure is kept within safe limits.

Why is it called Nuclear Medicine?

It refers to medicine (a pharmaceutical) that is attached to a small quantity of 

radioactive material (a radioisotope). This combination is called radiopharmaceutical. There 

are many different radiopharmaceuticals available to study different parts of the body. 

Which radiopharmaceutical is used will depend upon the condition to be diagnosed or treated.

C. Imaging

A gamma camera converts gamma rays into electronic pulses which make up an image. 

These pulses are collected over a period of time and build up a picture of the organ. These 

pictures are stored on disc and can be viewed and processed at a later date.

H.pylori. It is highly reliable- 95% sensitivity and 100% specificity, for pre- and post- 

treatment follow up of infection.
