Fig. 7. A, low-power (X 9), and B, high-power (X 30) microradiographs 

 of a cross section of the femur of a 78-year-old female showing the porotic 

 phase of Paget's disease with the large number of spaces, mosaic pattern of 

 mineralization and bone formation (a and b), and resorption (c, d, and e) 

 taking place on nearly all surfaces (formation 50 per cent, resorption 140
