Use of Radioisotopes imaging versus U/S imaging for detection of the thyroid Goiter

Abstract

In this study the researcher assessed the effectiveness of ultra sound and nuclear medicine images in the diagnosis of thyroid enlargement and compared between the two imaging modalities ( nuclear medicine and ultra sound ) ,when they are applied for the same case. This study was conducted at RICK, nuclear medicine department, ultra sound departments, surgery departments in Khartoum State Hospitals , and ultra sound department in College of Medical Radiologic Science. Random sample of fifty patients, males and females with different ages and symptoms were chosen, ultra sound and nuclear medicine images were done to demonstrate thyroid goiter. Some of these cases, had the same diagnosis by the two image modalities while the majority of these diagnosed only by nuclear medicine. Ultra sound imaging has a role in the diagnosis of thyroid goiter but nuclear medicine scanning is better and more sensitive. It can be said that the two imaging modalities when performed together can help to obtain and demonstrate any anatomical variation and pathological changes.
