I would like to measure the area and diameter of thyroid follicles on a photomicrograph using image J (see attached image). Does anybody have a simple method for doing this given the large number of follicles in a single image?
What I am specifically hoping is possible.
1) Get an area/diameter for the entire follicle including the epithelium lining (in the high mag image this is the dotted black line)
2) Get an area/diameter of the colloid (blue dashed line and star region)
I would like to do this for the low magnification image attached that shows the large number of follicles separated by "interstitium" which is connective tissue and blood vessels.
