Quantitative CT scan in diagnosis of osteoporosis in high risk patients in Babylon, Iraq

Abstract EN

The measurement of bone marrow density is one of best ways for diagnosis and monitoring of bone health, the bone mineral density of hip and spine is most commonly used because they are of great risk of fractures.

For analysis of the bone density T score and Z score are used, T score is derived by comparing BMD to BMD of healthy adult of the same sex [25 years age], and Z score with same age group.

for evaluate the bone density measurement by Cat scan densitometry as alternative tool of DEXA machine for diagnosis of osteoporosis in Babylon province in different age groups and risk groups 120 patients from both sex had been evaluated for osteoporosis in Merjan teaching hospital between 2009 and 2010 using quantitative CT Scan densitometry all were at risk of osteoporosis because the post menopause age or with other risk factors, steroid usage patients, connective tissue disorders or other illness that result in osteoporosis.

The female patients were [90] 75 % and the male were [30] 25 % All the patients that exposed to the test lumbar spine between L3 and L5 with average result of T and Z score ,the age was range from 18-84 years and the mean age was 63 + -,53 [44.1 %] of them were without any risk factors [only female post menopause age above 60, 35 [29.1 %] patients were on steroid drugs at least was for one year period, 21 [17.5 %] patients were suffer from connective tissue disorders, 15[12.5 %] were rheumatoid arthritis, 5 [4.1 %] patients were lupus and 1 patient was Sjogerns disease.

The result of T score for all patients was 45.4 % was less than-2.5, 48 % of them were between -1 to -2.5and only 6.6 % was less than-1.

The CT for detection of osteoporosis is important tool for diagnosis of osteoporosis and its structural changes in the vertebral spine.
