Question

metastatic lesions become radiographically apparent when _______ of the bone is destroyed.

a) 0 - 10%

b) 70 - 90%

c) 5 - 25%

d) 30 - 50%

question 6 (1 point)

Explanation:

Radiographic detection of bone metastatic lesions requires a significant enough loss of bone density and structure to be visible on imaging. Clinical and radiological standards note that this occurs when 30-50% of the bone matrix is destroyed, as smaller amounts of destruction do not create enough contrast to be seen on radiographs.

Answer:

D) 30 - 50%
