what causes you to need to get an injection to do a bone scan to check for a stress fracture?

Radiotracer: A nuclear medicine bone scan is used to evaluate for conditions affecting bones including cancer, fractures, degenerative diseases etc. The radiotracer or radioactive material used is injected through a vein quickly reach your bones where it is deposited. A gamma camera is used to detect the radiotracer and images are created. The radiation is cleared from your body mostly in urine.

A bone scan is significantly more sensitive than Xray for determining a stress fracture. It takes on average a 50% density change on Xray to see an abnormality vs about 10% on a bone scan.

The bone scan also detects the stress fracture changes much earlier than X-rays

Bone metabolism: Radiotracer technetium 99m mehylene diphosphonate or similar agent is injected intravenously to be transported by blood stream to the bones. Full deposition usually takes 2 to 3 hours. This agent goes where there is increased bone metabolism or repair of bone, such as fractures, tumors, arthritis, and infection. It detects subtle changes, sometimes not noticed on routine imaging.

My father died about 5 years ago from multiple myeloma. I was the bone marrow donor for his transplant. I am an only child and am wondering about my risk factor for myeloma, especially since my marrow was considered a good match.

About 2X risk: Sorry to hear about your dad.Being a donor doesn't change your risk. Multiple myeloma is not classically thought of as a familial/inherited cancer. However, the risk of a hematologic malignancy (mm, lymphoma, leukemia) in family members is thought to be about two times higher.

Dr. Barry Rosen
General Surgery 34 years experience
Yes: A simple blood test is available to check if someone carries the trait responsible for many forms of the hereditary type of breast cancer. The brca test should only be performed on those at high risk, and only after counseling by a specialist in hereditary diseases. In general, if you have two close relatives with breast or ovarian cancer, especially at an early age, you may qualify.

Could a bad dental bone infection cause thyroid problems?

No.: These two problems are not related. However, if a dental bone infection were to go untreated, it could spread to the neck. The inflammation and infection could wrap around the thyroid. Once in the neck, it can even spread down into the chest.
