Abstract
Background: Pulmonary Embolism (PE) is a major cause of morbidity and death in patients 
worldwide. PE is a common and potentially fatal disease that is caused by a perfusion defect due to an 
embolus blocking blood flow in the lungs. Aim: Aim of this study is to assess predictive value of 
chest ultrasound in diagnosis of pulmonary embolism using computed tomography pulmonary 
angiography (CTPA) as a gold standard. Material and Method: In this study seventy three patients 
of suspected pulmonary embolism were attend to the emergence unit of chest, cardiology departments 
at Minia Cardiothoracic University Hospital in the period between June 2018 to October 2019. The 
patients were included according to inclusion criteria listed later. The patients were evaluated 
clinically and assess risk factors and probability scores (modified wells criteria). Then, Thoracic 
Ultrasonography (TUS) was done. Multi-slice computed tomography (MSCT) was the reference gold 
standard method in this study. MSCT scans were interpreted by a radiologist who was unaware of the 
TUS results. Predictive value of chest ultrasound in diagnosis of pulmonary embolism was evaluated 
by measuring sensitivity, specificity, positive predictive value (PPV), and negative predictive values 
(NPVs) of thoracic ultrasonography. Results: In this study, sensitivity, specificity, PPV, NPV, and 
accuracy of chest ultrasound (CUS) for PE diagnosis were 81.25%, 95%, 98.3%, 77.3% and 87% 
respectively. Conclusion: TUS is a bedside, safe, easily available, noninvasive method for early 
diagnosis of PE in emergency department and in situations where CTPE couldn't be used.
