What is the best way to diagnose osteoporosis?
To diagnose osteoporosis and assess your risk of fracture and determine your need for treatment, your doctor will most likely order a bone density scan. This exam is used to measure bone mineral density (BMD). It is most commonly performed using dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry.
When should a DEXA scan be done?
Who should get a bone-density scan? For women over 65 and men over 70, DEXA scans are only appropriate for those with moderate risk of fracture or when the results will change the patients care plan. Younger women and men ages 50 to 69 should consider the test if they have risk factors for serious bone loss.
What does osteoporosis look like on xray?
Radiographic features Decreased bone density can be appreciated by decreased cortical thickness and loss of bony trabeculae in the early stages in radiography. Bones like the vertebra, long bones (proximal femur), calcaneum and tubular bones are usually looked at for evidence of osteoporosis.
Can osteoporosis be seen on MRI?
MRI has a role in detecting osteoporosis that the appearance of bone marrow is determined by its relative amount of protein, fat, water, and cells on MRI pulse sequence.
How accurate are DEXA scans for osteoporosis?
Depending on the study you read, the variability between DXA scans can be as high as 5% to 6%. Although 5% to 6% might sound like a small amount, changes in bone growth are measured down to the hundredth and even thousandth decimal point.
How often should you have a DEXA scan if you have osteoporosis?
How often you should have your BMD measured depends on your age and results of your previous DEXA scan. Women 65 years and older with normal bone mass or mild bone loss can have a test every 15 years. More frequent testing is recommended for women in this age group with T-scores between -1.5 and -2.49.
