Construction of a predictive model for gastric cancer neuroaggression and clinical validation analysis: A single-center retrospective study

Figure 1 A case of PNI in a 76-year-old elderly woman with gastric cancer. The tumor was located on the small curved side, and the region of interest was 110 mm². A: Computed tomography (CT)_{60 keV} in single-energy images of the arterial phase; B: CT_{70 keV} in single-energy images of the arterial phase; C: CT_{80 keV} in single-energy images of the arterial phase; D: CT_{90 keV} in single-energy images of the arterial phase; E: CT_{100 keV} in single-energy images of the arterial phase; F: CT_{110 keV} in single-energy images of the arterial phase; G: Iodine base map.
