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 absorptiometry (RA) then single energy photon absorptiometry (SPA) then single energy X-ray absorptiometry (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 the complaint or effect by problem in it ,therefore we tried to give reference guidance to take care in early stage to avoid any complication that can occur in future. This study performed in Antalia medical center of computer tomography in Khartoum state on 40 patients with different ages and variable range from (22-95) years old, sex (20 males and other 20 are females) and complains but all of them under went abdomen investigation. And study concentrate on measure the average of bone dense of the L2-L3 by using CT number. And we measure on 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 in bone dense on male rather than female and that appear clearly in increase the average of compact and spongy bony as is (387.30- 149.75) this reading for compact and spongy respectively but female bone dense average is (337.11-140.72) this reading for average of compact and spongy respectively, with (-or+) 82.996 for male and (-or+) 69.513 for female and these return to sexual hormone effect. The relation of average of compact and spongy with sex and age range is weak and opposite propagation. The relation of average of compact and spongy bone generally not strong but there are positive propagation and that refer to union body nutrition.
