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.
Micrometre is 1 millionth of a meter, 1 thousandths of a milimeter (mm), or 1 x 10-6 meters. To give you the idea of how small a micro metre is, a human hair is about 100 Âµm, wide, and a red blood cell would be around 8 Âµm wide, the typical size of an animal cell would be from 10 - 100 Âµm.NSWER Generally in Science, you would use the Metric system of measurement. Therefore, when talking about cells and microscopic organisms, you would be measuring using MICROMETRE (abbreviated: Âµ --micron) or stated as: Âµm (micro metre).
