To many @entity1 die because of undiagnosed @entity1151 . Common @entity1151 is the most unexpected mortal event in necropsy, antemortem correctly diagnosed in 18-39%. The diagnostic value of chest ultrasound (CUS) has been investigated. METHODS: 117 (68 @entity1 , 49 @entity1 ) @entity1 with clinical suspicion of @entity1151 underwent chest sonography and spiral computed tomography (CT). Final diagnosis has been made by CT respective with echo-cardiography, venous duplex sonography and fibrin dimer tests. RESULTS: Finally, 70 @entity1 suffered from @entity1151 . The chest sonograms showed averaged 1.5 x 2.8 cm (0.5-8.5) large triangular or rounded @entity75 , mean 2.6 pro @entity1 , similar in form and size as in CT. Fresh reperfusionable @entity1188 were homogenous and hypoechoic. Older @entity1188 were well demarcated, mainly wedge shaped. A hyperechoic reflex in the center corresponds to the bronchiole: a sign of segmental involvement. The sensitivity of chest ultrasound was 94%, the specificity 87%, positive predictive value 92%, negative predictive value 91%, accuracy 91%. Overall 61 @entity1 had PE in CT, in 47 (67%) cases a direct emboli detection was possible. 14 @entity1 had peripheral lung consolidations without detectable emboli, but fibrin-dimer tests were positive in all cases, there was deep vein @entity715 diagnosed and they showed signs of PE in echocardiography. Spiral CT showed a sensitivity of 85%, a specificity and a positive predictive value of 100%, a negative predictive value of 83% and an accuracy of 92%. CONCLUSION: CUS can improve diagnosis of @entity1151 . Sonography also reveals small @entity1188 which remain undetected with other imaging procedure such as helical CT.
