Nuclear Medicine

  
Nuclear medicine is a branch of medical imaging that uses small amount of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body because nuclear medicine procedures are able to pinpoint molecular activity within the body. They offer the potential to identify disease in its earliest stages as well as a patient’s immediate response to therapeutic
intervention. 

Diagnoses

Nuclear medicine imaging procedures are noninvasive and with the exception of intravenous injection are usually painless medical tests that help physicians diagnose and evaluate medical conditions,these imaging scans use radioactive materials called radio- pharmaceuticals or radiotracers.
Depending on the type of nuclear exam,the radiotracer is either injected into the body, swallowed or inhaled as a gas and eventually accumulates in the organ or area of the body being examined.Radioactive emissions from the radiotracer are detected by a special camera or imaging device that produces pictures and provides molecular information.
