Measurement of Thyroid Gland Volume for Sudanese using Ultrasonography

Abstract

Thyroid gland is one of the major glands of the body and plays a vital role in metabolic process. The main objective of this study was to measure the thyroid dimensions for normal Sudanese in Port-Sudan and Kordofan for normative data. The study conducted in Alneelain university Almogran teaching hospital Medical College, in the period from June 2016 to September 2016. This study consisted of 100 normal patients 50 from each region (Port-Sudan and Kordofan). The data of this study collected using Toshiba ultrasound machine with 7.5 MHz linear transducer. The results of this study showed that there is no significance differences between male and female at p = 0.05 using t-test. The results also showed that there is a significance differences between thyroid volumes in Port-Sudan and Kordofan sample using t-test at p = 0.05 where for Port-Sudan the volume equal 5.74±1.7ml and 7.22±2.2 for Kordofan. As well as the width, depth, isthmus and lobe volume, where thyroid length did not showed a significance difference. The results also showed that for Port-Sudan sample concerning thyroid Rt lobe volume, it showed a direct linear relationship with body weight, age and BMI; the volume increased by 0.049ml/Kg, 0.064ml/years and 0.156ml/Kg/m2 respectively. While for Kordofan sample showed a direct linear relationship of Rt lobe volume with body weight and age; the volume increased by 0.061ml/Kg and 0.087ml/year.. The volume of the Lt lobe for Port-Sudan sample follow the same pattern as the Rt one where it showed a direct linear relationship with body weight, age and BMI and hence the volume increased by 0.042ml/Kg, 0.058ml/year and 0.132ml/Kg/m2 respectively. While for Kordofan sample the volume of the Lt lobe showed a direct linear association with body height and age where the volume increased by 0.041ml/cm and 0.07ml/year respectively.
