What is the difference between a bone scan and a bone density scan?

Bone scans are performed by injecting a radioactive material, that is taken up more rapidly by bone with a relatively high metabolic rate than by bone with a relatively low metabolic rate. In other words, in regions of bone where the bone tissue is undergoing rapid change, the radioactive material will concentrate to a greater degree. Examples of areas where this rapid change occurs are fractures, tumors, areas of inflammation (Arthritis), etc. The radioactivity is then read by a special detector which produces an image of the skeleton, enhanced by areas of increased metabolic activity. Bone density scans, on the other hand, are performed with specialized x-ray equipment. It has been known for a long time that a bone's strength is related to how much calcium and other minerals are contained in the bone tissue. It has been further known that bone mineral tends to absorb x-rays. This is why x-rays show bones so well. The bone density (or DEXA) scan measures how much the x-rays are absorbed by the bones and then calculates the relative density of that bone. By comparing the number generated with the normal values, it can be determined whether a patient's bones are abnormal. This test is used primarily to diagnose osteoporosis.

How do you determine the heath of a bone?
A bone scan can show if a bone is healthy or if it is losing strength and density by becoming porous.
What is a nuclear scanning test that identifies new areas of bone growth?
bone density test
What is a bone density test used for?
Post-menopause unless there's a reason to do it sooner.
CAT scan after bone removal can not be seen by a surgeon or radioligist. Is this possible?

How a broken bone can be seen?
In X-ray or CT scan as crack in the surface of bone.
What does a DEXA scan measure?

What test checks for osteoporosis?
There are a few different tests which are used to check for osteoporosis. The most common is the DEXA scan. Other methods are blood tests and bone densitometry.

bone density test
How can one get diagnosed with osteoporsis?
Ask your doctor for a bone density scan.
How can you know what some weak bones in the human body are?
Get a Bone Density Scan.
Will Blue Cross Blue Shield cover a bone density?
no I have BCBS Open Access and had 2 different scans. First was a Triple Phase Bone Scan and second was a DEXA Scan last Friday. BCBS covered all of the bill. Without prior approval.
What is the history of bone scan?
John R. Cameron is credited with inventing a way to study bone density. Following this, companies were able to develop bone densitometers and now bone scans.
How much does a bone density scan cost?
Depends where you live. You have not told us that so we cannot answer your question.
What is a bone scan?
i want to know what actually goes into a bone scan. A nuclear medicine bone scan images the physiology, or function of the bones in the body. An injection of the material your bones use to repair themselves if given to the patient. The only difference between the drug and the natural substance is tha we attach a radioactive atom to each of the drug molecules so that our cameras are able to image the drug as the body uses it. The idea of the scan is that any damage or abnormality of the bone will have an increase, or decrease in bone repair, therefore showing up lighter, or darker on the scan.

Post-menopause unless there's a reason to do it sooner.
