Effectiveness of chest radiography, lung ultrasound and thoracic computed tomography in the diagnosis of congestive heart failure

Figure 6 A typical sonographic pattern of diffuse alveolar-interstitial syndrome (left side) and corresponding chest radiograph (right side) in a case of acute cardiogenic pulmonary oedema. In the sonographic images on either side of the radiogram, the presence of multiple adjacent comet-tail artefacts (at least three per scan and in all chest areas examined) can be easily distinguished. The images illustrate the sonographic B+ pattern corresponding to the radiological finding of pulmonary oedema.
