Fig. 2From: Potential of high dimensional radiomic features to assess blood components in intraaortic vessels in non-contrast CT scansRepresentative images of the measurement technique. Axial (a), sagittal (b) and coronal (c) plane with 3D-volume rendering (d) of a standard volume of interest (VOI) placement is shown in a patient with a hemoglobin and hematocrit level of 7.2 g/dL and 22.4%, respectively. A spherical VOI with 1 cm in diameter was placed within the lumen of the thoracoabdominal aorta as described in detail in the materials and methods sectionBack to article page
