Fig. 1From: Impact of pericardial fluid glucose level and computed tomography attenuation values on diagnosis of malignancy-related pericardial effusionMeasuring CT attenuation values in pericardial effusion. Two-dimensional images in three axial views: a upper slice: bifurcation of the pulmonary trunk, b middle slice: four-chamber heart view, c lower slice: upper edge of the liver. Both computed tomography (CT) attenuation values (in Hounsfield units (HU)) and pericardial effusion area were measured by plotting around the pericardial effusion in the three axial slices. The respective results were a 5022 mm2, 19.7 HU; b 6728 mm2, 18.4 HU; and c 12,335 mm2, 17.7 HUBack to article page
