Nuclear Medicine Scan: An Advance In Medical Imaging Technology
A nuclear medicine scan can be described as a test wherein radioactive materials are taken inside the body and utilized for creation of images of a specified bone or organ. The scan helps in locating the areas of impaired functions within the bone or organ that is being scanned. Such scans are extensively utilized for diagnosing and monitoring variety of conditions. Moreover, during diagnosis as well as treatment of cancer, these scans are utilized for identification of cancerous sites, staging and localization of tumor as well as examining the response to a therapy.
The scan is considered to be a highly sensitive test which provides information about the function and structure of specified body parts. The different types of nuclear scans incorporate heart scans, bone scans, lung scans, bladder and kidney scans, spleen and liver scans, gall-bladder scans and thyroid scans. Moreover, brain scans are performed for detection of malignancy.
During a nuclear medicine scan, a small quantity of tracer or radioactive material is taken orally or injected. After a certain period of time when the radioactive material gets accumulated in a particular area of body, the scan is taken using a radiation detector known as radionuclide scanner. This machine creates images of the area which are used for analysis by doctors.
The risks of such scans are extremely low. Majority of scans utilize similar or lesser amount of radiations as a traditional X-ray. During the scan, radioactive material is passed through the patient’s body. The test does not produce any negative reaction or side effects.
