Our objective was to study agreement between the compression ultrasound images taken in our respiratory medicine department and the duplex ultrasound images obtained by radiologists at our hospital for patients admitted to our ward with suspected diagnoses of venous thromboembolism.Seventy-eight consecutive patients admitted to our respiratory medicine ward suspected of venous thromboembolism were enrolled. Both types of images were available for all patients studied. Agreement was 90% with a Kappa coefficient of 0.81. Agreement between the two techniques was good. Therefore, compression ultrasonography is a technique that can be handled by respiratory medicine specialists for the diagnosis of venous thromboembolism.
