Deering. Learning Objectives. Explain how the structure of bone allows it to carry out its functions; . (strong due to hydroxyapatite crystals, flexible due to collagen, good loadbearing due to honeycomb structure). Maximum . energy of emitted x-ray beam depends on tube voltage . applied . across the x-ray tube;. As . x-ray tube voltage increases, average x-ray photon energy increases, . and . total x-ray intensity increases. Lecture no. 3. Prepared by Dr.Salah Mohammad Fatih. MBChB,DMRD,FIBMS(radiology). Multiple focal lesions. Metastases & multiple myeloma are most common cause of obvious multiple lytic lesions in the bone.. Who gets this test done?. Why is it . needed?. How many different types?. What do the results mean?. Bone Mineral Density. HHHOLDORF. A bone mineral density test or BMD measures how much calcium and other types of minerals are in an area of your bone.. Bone density scanning, also called dual-energy x-ray . absorptiometry. (DXA) or . bone. . densitometry. , is an enhanced form of . x-ray. technology that is used to measure bone loss.. DXA is today's established standard for measuring bone mineral . An x-ray radiograph is a painless medical test that helps physicians diagnose and treat medical conditions Radiography involves exposing a part of the body to a DEXA is also effective in tracking the In general , metabolic bone disease affects the skeleton in one of two ways : there is either too much or too little calcified bone .The latter change , which comprises the majority of metabolic bone disease , is due either to decrease in the amount of bone formed , or to excessive resorption of bone. In turn this may be due to a variety of causes but most commonly to abnormalities of vitamin D and calcium metabolism , which in turn arise from abnormality of diet or renal function , endocrine abnormalities ( particularly of the parathyroid gland) , drug therapy or poisoning ..

It is a potentially progressive and debilitating disease in which bones become fragile and more likely to break. In fact, osteoporosis is a leading cause of fractures in both Iran. J. Radiat.
