Spencer and Waldman developed equations for evaluating the thyroid gland. The authors are from Yale University.
The right lobe was found to be about 11% longer and 23% heavier than the left lobe.
length of the right lobe in cm =
= (0.94 * (length of the left lobe in cm)) + 0.8
length of the left lobe in cm =
= ((length of the right lobe) - 0.8) / 0.94 =
= (1.064 * (length of the right lobe)) - 0.85
volume of the left or right lobe in mL =
= PI()*(((diameter in cm)/2)^2)*(length in cm)
total volume of the thyroid =
= (volume for the left lobe) + (volume for the right lobe)
The authors estimated that the density of the thyroid gland was 1 g per mL.
weight of the thyroid gland in grams =
= (volume of the thyroid gland in mL)
