Measuring the short-axis diameter is better than measuring the long-axis or greatest diameter because it more closely reflects the actual node diameter when nodes are obliquely oriented relative to the scan plane and shows less variation among healthy individuals. Hilar lymph nodes are those located around the entrance to each lung on its medial side; the bronchi and pulmonary blood and lymphatic vessels enter and leave the lung through this .
