ABSTRACT
Lung radiology is regularly done for the patients in intensive care units (ICU). Chest x-ray (CXR) consider One of the most easily imaging modalities. However, CXR may be not comfortable for critical patients as well as produce hazards of irradiation. The highly variability of quality of the CXR image make CXR interpretation difficult. To show the effect of lung ultrasound (LUS) in ICU patients and diagnose pulmonary diseases compare with chest radiography. This was a prospective study done on 60 patients has acute dyspnea transmitted to the ICU of Alzahraa University Hospital. Sonographic examination of the chest and chest radiographs done to all patients. Sixty patients included in the study with acute dyspnea, CXR and LUS was done to all the patients and then compare between two modalities for diagnosis of pulmonary diseases. Ultrasound is abed side tool useful for rapid and early diagnosis of acute dyspnea in critical ill patients. LUS represents high sensitivity and high specificity of diagnosis of chest diseases as pneumonia, pleural effusion, pneumothorax and interstitial lung diseases compared to CXR.
