QCT- (Quantitative Computed Tomography) Bone Densitometry uses our CT scanner to quantitatively measure trabecular bone in the spine. OCT has several advantages over DXA, providing true volumetric density separately in trabecular and cortical bone with much better fracture discrimination. Bone Densitometry Testing can: Help confirm a diagnosis of osteoporosis before a fracture occurs
Document low bone mass in asypmtomatic women and men at risk
Help to provide a guide for treatment decisions
Why measure Bone Density in the spine with QCT
Osteoporotic fractures tend to occur first in the vertebral bodies.
The vertebral bodies consist primarily of trabecular bone.
Trabecular bone is affected earlier then cortical bone.
Trabecular bone has a turnover rate much higher than cortical bone, thus making the spine an ideal site for measurement of osteoporosis and for assessing treatment.
25 million Americans are affected by osteoporosis/making it a major public health problem.
50% of women over the age of 50 have an osteoporosis-related bone fracture.
By age 75, a third of all men are affected by osteoporosis
Osteoporosis is responsible for 1,300,000 fractures annually
OCT Bone Densitometry Benefits:
Quickly identify low bone density
Highest diagnostic accuracy of any BMD technique
Painless, comfortable 10-minute exam for patients
Low dose exposure to patients
Reimbursable by most private insurance carriers and Medicare
Precautions and Preparation:
There is radiation involved with this scan and if there is any possibility of pregnancy, the scan should not be done until pregnancy is ruled out.
Do not take any calcium supplement/vitamin the day of the exam prior to your exam time.
If you had any x-ray exam with contrast material or nuclear medicine isotope study within the last 7 days, the exam should be postponed at least 7 days since the exam has passed.
