WebFigure 10.7 Mean CT attenuation values (Hounsfield unit, HU/pixel) immediately and 7 days after injection with W/OAV emulsion. The values were calculated by using numeric data of randomly selected 250 pixels in a main tumor, juxta-tumor nontumorous tissue within an area up to 10mm from the edge of the tumor, and nontumorous tissue 10 mm distant ...
The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature (STP) is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU. In a voxel with average linear attenuation coefficient , the corresponding HU value is therefore given by: WebAn attenuation difference between kidneys greater than or equal to 5.0 H had 61% sensitivity, 100% specificity, 100% positive predictive value, 69% negative predictive …
