As opposed to what? Technetium is pretty much the radionuclide of choice for most nuc med scans, it's got a good energy (140 kEV), a low half life (6 hrs) and it's cheap and readily available.

What radioactive marker is used for salivary gland scans?
a low-level radioactive marker, usually technetium-99m or technetium pertechnetate.
What are some common uses of technetium?
Some common uses of technetium include medical imaging, specifically in the form of radioactive isotopes for bone scans and heart imaging exams. Technetium is also used in industrial applications, such as measuring the thickness of materials and detecting leaks in pipelines. Additionally, it is used in scientific research and as a tracer in environmental studies.
Why are bone scans ordered?
Bone scans are most frequently ordered to check whether a cancer that originated elsewhere has spread to the bones.
How is technetium-99 used in the medical field?
It is used in medical scans it helps cancer victims by using nuclear radiation
What are radionuclide bone scans?
Radionuclide bone scans. These scans involve injecting a small amount of radioactive material into a vein. Primary tumors or cells that have metastasized absorb the radioactive material and show up as dark spots on the scan.
What tools can best measure bone density?
more likely to catch osteoporosis at an early stage are computed tomography scans (CT scans) and machines called densitometers, which are designed specifically to measure bone density
What are staging procedures in diagnosis of lung cancer?
A chest x ray may be ordered to check for masses in the lungs. Special imaging techniques, such as computed tomography (CT) scans or magnetic resonance imaging (MRI),
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.
Where can I find information on a bone scan?
To find out information about bone scans, consult the website webmd.com or the website mayoclinic.com. They both have a great description of the procedure.
Do you need a bone scan after having a contraceptive implant for 3 years?
Bone scans are not recommended as follow up to any birth control method.
Are there certain tests a doctor can do to see if you have bone disease?
Yes, they can perform blood tests, xrays, CAT Scans, MRI. Bone density test. They might also do a bone marrow test.
Why is there no technetium in nature?
Technetium exist in nature only in ultratraces; being unstable technetium technetium was lost by radioactive decay.
