Optimization of Exposure Factor For planner lateral Skull Radiograph

Abstract

CT scan is play important role in diagnostic radiology and valuable in Sudan have amore advantage like study of sectional anatomy, evaluate the texture of soft tissue, three damnation imaging and fast sequence examination. The aim of This study intended to measurement the retrosternal goiter mass, level of extension and texture of mass. Random samples consist of 22 patients who underwent CT scan for chest or neck examination. The patients IX were registered (age, gender, HU, AP diameter, right to left diameter, texture of mass and extension) . Out of this sample,15(68%) patients were females while the 7(32%) were males and their ages ranged from 20 to 80 years old. The study was done in – ( Royal care) and (Khartoum teaching hospital) hospital-Khartoum. The study finding mean CT number was 119.2±24.2 and the range was 97 to 163 HU for middle level per procedure, The mean of AP diameter in middle level 59.2±13.5 mm and rang 37 to 91 , The mean of Right to lift diameter in middle level is about 50.2±18.5 mm and rang 19 to 86, the most texture are calcified and the extension level in most patient C4-5 to T4-5. The study shows measurement of retrosternal goiter for this study were smaller than the most previous study.
