The high specificity at 10 and 11 mmindicates that lymph nodes of this size are almostalways metastatic in this level.A study of level II lymph nodes shows that for thewhole population a minimum diameter of 8 mm givesa relatively high sensitivity and specificity of 81% and80%, respectively.
Small, rounded structures along the small vessels of the lymphatic system that are part of the immune system. Lymph nodes are tiny spherical structures the size of a pin hea â¦ d in groups into which the lymphatic vessels drain through afferent vessels.The nodes filter the lymph, storing and destroying microorganisms by the production of lymphocytes. Once filtered the lymph leaves the node through the efferent lymph vessel.ymph nodes are tiny spherical structures the size of a pin hea â¦ d in groups into which the lymphatic vessels drain through afferent vessels.
