Role of Ultrasound in Measurements of Normal Thyroid Lobes

Abstract

The objective of this study is the detection of the relationship between thyroid volume and age, sex and body weight in normal patient in Quayeyya region (Kingdom of Saudi Arabia 2006 to 2007). This study depends on practical scanning through which the data was collected. The data was collected from August 2006 to November 2007. Patients from different areas of Quayeyya region were scanned in government hospitals which include: Quayeyya general hospital, Ruayda general hospital and Alkhasra general hospital. Using a precise and accurate ultrasonic scanning technique we have measured the volume of the thyroid gland in 241 healthy peoples the general average was ( 18.4 ml. ) difference between males thyroid volumes average is ( 19.4 ml ) and females thyroid volumes average is ( 17.5 ) was found ( 1.9 ml ). And from the values above we can detects that the thyroid volume was significantly correlated with both body weight and age, the influence of body weight on the thyroid volume was greeter than that of age. The difference in thyroid gland volume between males and females was explained by difference in the body weight. Ultrasound of thyroid gland must be done early to discover the abnormality if present, and look for suitable solutions, also it is accurate modality for detecting the thyroid gland abnormality because it is non –invasive, cheep, and available method.
