Bone scan

Bone imaging is a study to visually detect bone abnormalities.

Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and especially nuclear medicine.

In the latter case the patient is injected with a small amount of radioactive material such as 600 MBq of technetium-99m-MDP and then scanned with a Gamma camera, a device sensitive to the radiation emitted by the injected material.

About half of the radioactive material is localized by the bones.

The more active the bone turnover, the more radioactive material will be seen.

Some tumors, fractures and infections show up as areas of increased uptake.

Others can cause decreased uptake of radioactive material.

About half of the radioactive material leaves the body through the kidneys and bladder in urine.

The period from injection to completion can last over 4 hours.

Actual images are taken for about 30 to 70 minutes.

Sometimes late images are taken at 24 hours after injection.

Pregnant patients should consult with a physician before consenting to radioactive injections.

Brave New World of Genetic Testing

France 24 (Jan. 6, 2014) Genepeeks is a new company in the US offering a service to mothers to scan the genome of any potential sperm donors to pinpoint any anomalies that could cause dangerous or fatal diseases to a future child. Critics say it's the first step towards "designer babies" - being able to pick and choose what kind of baby you want. But supporters say it's simply a way of ensuring your child is healthy - surely a wish of any parent.
