Abstract:
HRCT and CXR are the important radiographic procedures during the management of lungs disorders. This study aimed to evaluate diagnostic accuracy of HRCT and chest radiography in diagnosis of lungs disease .A total of 50 patients were examined in Sudan University of Science and Technology (SUST)-College of Medical Radiologic Sciences (CMRS) and Khartoum Modern Diagnostic Center. In the period (October 2010-june 2011). the majority of samples were males (60%) and females (40%). In this study peak incidence was among the age between (41-60 years) of age presenting (34%). The cough is the most clinical indication with (100%) incidence. Chest X-ray examination showed normal appearance in (18%). The most common finding in HRCT is Bronchiectasis (40%). Some of normal CXR appears abnormal in HRCT. normal chest patients showed in HRCT (sensitivity 67%, Specificity 93%, Accuracy 88%). chest x-ray alone especially in first stage diseases is mostly unsuitable in order to differentiate between normal and early pathological development . HRCT is superior investigation tool in detecting lung abnormalities.
