How is radioisotope scan test done?

As already stated, radioisotope scan relies on information obtained from a radiation source inside the human body.Therefore,the radiopharmaceutical as it is called, has to be introduced inside the human body. This can be done in many ways-

  • Injection into a vein with the help of a needle (usually the inside of the elbow)
  • Through a synthetic tube inserted into a blood vessel (artery or vein) which is then directed to the organ of interest.
  • Through
Ingestion- in the form of a pill which the patient swallows.
  • Injection under the skin
  • The mode of administration of the radioisotope would differ depending on the organ to be studied. For example, to image iodine, the patient may be asked to swallow a tablet and for imaging of the kidney, the patient is usually given the medication in the form of an intravenous injection.
