Abstract
Diaphragm position and shape on chest radiographs are routinely used as indicators for diseases. Previous population studies were done for normal diaphragm position and shape. The study was done to determine the distance between right and left hemi diaphragm in normal Sudanese adults using digital radiography. The study sample was 100 subjects, 50(50%) were males and 50(50%) were females, with different ages ranged from 18 - 82 years old; all subjects were with normal abdominal ultrasound and normal chest radiographs. The study was done in Fedail hospital in the period from January up to March 2013. The measurements were done on ideal postero anterior (PA) chest radiograph by measuring the difference between the distance from the highest point of right hemi diaphragm and highest point of the left hemi diaphragm. The result showed that the right hemi diaphragm was higher than the left in 98% of total sample and the left was higher in 1% and they were in the same height in 1%. The right was higher in range of 1cm to 2.5cm in 79% and the Male diaphragm height difference ranged between0.6- 2.8 and Female ranged from-0.5-2.9cm.The study found that there are linear relation between distance difference of right and left hemi diaphragm with subjects' age, body mass index (BMI), height and weight. Computed radiography was useful in measurements of diaphragm height difference for Sudanese as it is accurate and easy.
