The annotation of No. 253 LN region on CT images (a). The four views represent axial (top left), coronal (bottom left), sagittal (bottom right), and 3D (top right) images. The red area represents the aorta, the green area represents IMV, the blue area represents IMA, and the yellow area represents LCA. The upper boundary for annotating No. 253 LN was the starting point of IMA, with the right boundary being the left edge of the aorta, the left boundary being the right edge of IMV, and the lower boundary extending from IMA to the intersection of LCA and IMV. The annotation of all the lymph nodes in No. 253 LN region (b). The purple area represents the largest lymph node and the light blue area represents other lymph nodes in No. 253 LN region. LN = lymph node; IMV = inferior mesenteric vein; IMA = inferior mesenteric artery; LCA = left colic artery
