Objectives: After studying the article entitled “Quantitative Ultrasound of Phalanx in Primary and Secondary Osteoporosis: Mini-review and Practical Experience,” you will be able to:
Knowledge of bone densitometry and dual x-ray absorptiometry (DXA)
Describe the benefits of quantitative ultrasound (QUS) of the bone
Understand the gold standard for bone densitometry is DXA
What is the most common metabolic bone disorder? Rickets osteomalacia Osteoporosis Fibrous dysplasia Osteogenesis imperfecta
What is a cause of secondary osteoporosis? Chronic kidney disease Osteogenesis imperfecta Decreased estrogen production Advancing age
Which 3 locations are commonly measured for bone mineral density (BMD)? Forearm, spine, and sternum Femur, forearm, and sternum Sternum, spine, and hip Spine, hip, and forearm
What is measured with QUS of the phalanx to gauge bone density? Amplitude-dependent speed of sound Compression of the bone surface Reflection coefficient Contrast to noise ratio
What is the frequency of fracture from secondary osteoporosis with rheumatoid arthritis? 30% 40% 50% 60%
Which location was observed in this study to have a significant correlation between DXA and QUS? Femur Radius Humerus Spine
In which situation may QUS of phalanx be useful? Diagnosis of secondary osteoporosis Screening primary and secondary osteoporosis Differentiating normal and secondary osteo-porosis Diagnosis of primary osteoporosis
