Bone Density Scan
What is a Bone Density Scan?
A bone density scan evaluates bone mineral density. It is used to detect low bone mass and monitor the effects of therapy in patients undergoing treatment for osteoporosis.
Why test for Bone Mineral Density?
Osteoporosis effects an estimated 55% of people age 50 and older in the United States. It is characterized by the deterioration of bone strength and increased susceptibility to fractures. But it is treatable and preventable. Early diagnosis, therapeutic intervention and the use of bone density testing have improved the prognosis for patients.
What is QCT?
Quantitative Computed Tomography (QCT), the bone density scan used at Metro Imaging, is a fast non-invasive exam that utilizes CT to detect low bone mass earlier and more accurately than other bone density exams. It is widely used and one of three methods cited by the National Osteoporosis Foundation as safe and effective for the evaluation of bone mineral density.
How do I prepare for my Bone Density Scan?
Wear metal free clothing. Tell your doctor if you are, or suspect you might be pregnant.
What can I expect during my Bone Density Scan?
A QCT exam takes approximately 10 minutes and is similar to an ordinary CT scan. A registered technologist will position you on the exam table in a donut shaped gantry. During the exam, both the spine and hip are scanned. A low-dose CT scan is used and the amount of radiation required is comparable to a mammogram.
What will happen following my Bone Density Scan?
Your examination will be reviewed by the radiologist after the exam has been completed. If you choose OnSite Results, your preliminary results will be given to you before you leave our office. Your physician will be sent a detailed final report by fax or mail.
