Question

Quizplus · Accepted Answer

Research has shown that as much as 40% of bone mass must be lost before it can be detected on a standard radiograph. Therefore, general radiography is not an effective method for detecting early stages of bone loss or osteoporosis. Other imaging techniques such as DXA (dual-energy x-ray absorptiometry) or CT (computed tomography) scanning may be more effective in detecting bone loss at earlier stages.
