WebThe input features for the PNN algorithm consist of two patches of MR intensities chosen in both the co-registered UTE1 and UTE2 images. At the end, the PNN generates an image classified into four different classes: brain+soft tissue, air, csf, and bone. CT and MR data were acquired in four subjects, whereby the CT data were used for comparison. WebFurthermore, adrenal contrast-enhanced CT revealed a nodular soft-tissue low-density mass in the right adrenal gland (31 × 23 mm; Figure 1). Attenuation values were 30, 53, 77, and 62 HU during the plain scan phase, the arterial phase, the venous phase, and the delayed phase, respectively. Based on these results, AVS was performed.

WebIn physics, attenuation (in some contexts, extinction) is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates. ...
