Measurement of Normal Bone Density for Sudanese Patients Using Computed Tomography

Abstract

Measurement of bone density is one of important method that use international to decrease the problem of the bone which effect in life activity ,and the common method that use is DEXA which is best one that discover after many stages of development from radiological absoptiomerty (RA) then single energy photon absoptiomerty (SPA)then single energy X-ray absoptiomerty (SXA) . This study is attempt to measure the bone dense which a lot of us neglected it and never take care to it till after complain or effect by problem in it , therefore I try to give reference guidance to take care in early stage to avoid any complication that can be occur in future. This study performed in many diagnostic centers of computer tomography in Khartoum state on 58 patients with different ages and variable range from(4-76) years old ,sex (33 are male and 25 from them are female) and complains but all of them under went abdomen investigation. And the study concentrate on measure the average of bone dense of the L2-L3 by using the CT number. And we measure at this Because this area give accurate estimation to any change in bone in addition to it is one of world method to detect bone dense . The study show increase of bone dense on male rather than female and that appear clearly in increase the average of compact and spongy bone as is (301.571- 187.55)this reading for compact and spongy respectively but female bone dense average is(267-173.42) this reading for average of compact and spongy respectively ,with(-or+ )68.77 for male and(-or+)49.31 for female and that return to sexual hormone effect. The relation of average of spongy and compact with sex and age range is weak and opposite propagation. The relation between average of compact and spongy bone generally not strong but there are positive propagation and that refer to union body nutrition. The relation ship between the average of spongy and compact with pt have problem means pt with disease is negative propagation when increase the severity of disease the average of bone dense decrease .
