What is the difference between Bone Scan and Bone Density Scan?

The bone scan is a specialized diagnostic procedure to determine specific medical issues about the bones. It is a nuclear radiology test that uses a radioactive substance commonly known as a tracer. The material is injected into the bloodstream through a direct IV or IV infusion. A period of 2-3 hours is necessary to let the tracer amass within the bone tissues.

The tracer produces a type of radiation called gamma radiation. It makes it possible for the scanner to process information through images of bones. Bone density scan is sometimes referred to as DEXA, and it is one of the least stressful diagnostic exams you can have. It takes the lumbar vertebrate of the lower spine, hips, or upper section of the femur.

For this study, you will remove all metal objects off your person. This metal includes any jewelry or anything on you that may be metal. When the procedure is completed, the results will be measured in the form of what is called a T-score.

Our bones are fundamental parts of our bodies. They help us walk, write, use our hands to gesture, and even talk. As they are so important, it is vital to ensure that they are healthy so we can keep walking, writing, and talking with ease.

These are where bone scans come into play. A bone scan is performed to identify if any type of illness, such as cancer, has traveled into the bones. Bone density scan differs, for it is used to identify how strong the bones are. This type of scan is important in cases where the bones would thin out.
