Abstract:
This study is retrospective, analytic and experimental descriptive study by using of statistical package for social science (SPSS) because it gives more specific and accurate data analysis.
General objective to identify the role of CT scan in the diagnosis of bone density. Specific objectives to monitor the ability of CT scan to assess osteoporosis in patients with thyroid disorder, to monitor the ability of CT scan in assessing osteopenia and in an identify the role of CT scan in assessing bone density.
The study was done in ALgazira Scan hospital, Wad Madani for advance, treatment and diagnostic centre, Shakrin diagnostic centre & Algazir Centre for X-ray diagnostic. In the period between 2016– 2018 used CT scan to assess the bone density for 100 patients with thyroid disorder, whom their ages were range between (25 – 100 yr).
The result demonstrates that CT scan is most accurate and sensitive in diagnosing and evaluating bone density. CT scan is the most accurate and sensitive in diagnoses osteoporosis (100%) and osteopenia (100%).
Osteoporosis results by decreasing calcium serum in bone, increase when thyroid disorder (100%), increase when age increase ( 35.85% ), increase in females more than males ( 71.72% ) because post menopause females had decreased in estrogen level, increases when the patients obese ( 79.48% ), BMD decrease when height decrease ( 35.89% ).
Osteopenia results by decrease calcium serum in bone, increases when thyroid disorder (100%), increase when age increase ( 36.36% ), increase in males more than females ( 90.91% ) because BMD decrease when testestrogen level decrease and increases with the age in the males,

increase in the thin patients (81.82% ), and increases in height decrease ( 45.45% ).
Recommended every patients with thyroid disorder must be underwent CT scan examination to assess significant change in bone mineral density, every patient, such as patients on high dose of steroid medication, may need follow-up periodically by intervals of six months, CT scan modality should be introduced in the syllabus of the faculties of radiology and the post menopause female should takes estrogen to avoid decrease bone density.
