Abstract:
This is descriptive cross-sectional study aim to measure normal thyroid volume in women in White Nile State, using SONO Scope Italian company made in China machine using 7-15 MHz transducer in Rabic teaching hospital, the study had 50 normal women aged between 12-50 years old, affected age between 19-30 the mean of aged 27.78, all subject are examined in supine position with neck extended and measure thyroid from outer to inner and measure three plane, transverse, longitudinal, and depth. The main result of this study that affected thyroid volume was 5.1-7 mm percentage 46.3%, and maximum volume thyroid in this study was 9.1-11mm in percentage 14.8%, and minim volume of the thyroid in this study was 3.5 mm percentage 29.6%. The maximum aged of this study was 48 standard deviations (STD) of aged was 8.94. The study found that right lobe maximum volume was 5.5 mm and right lobe minim volume was 2.2 mm, and STD of right lobe was 0.95 and left lobe, maximum volume was 4.5 mm , minim volume was 1.2 mm, with STD was 0.92. The mean of age was 27.78, mean of right lobe was 3.55, and mean of left lobe was 2.27 the total mean of thyroid was 6.12. So that maximum thyroid volume was 10mm The affected thyroid volume was 5.1-7 mm in affected aged group 19-30 years old, the result shows the linear positive correlation between the right lobe and subject age with R2= 0.768 and positve correlation between left lobe and subject aged with R2= 0.676 so that the study shows that there is positve correlations between thyroid volume and aged. The study conclude that the normal thyroid volume increase with aged increase and there was small

increase in right lobe volume than left lobe volume, the study recommended that to increase sample size and using advance ultrasound imaging, and other study with other imaging modalities as comparative studies
