I am doing my research in the area of endometriosis and I need to find out the volume and surface area of an endometrial lesion in rat model .Can any one pls suggest how to calculate it.
A. You can estimate approximately the volume of endometrial lesion by using ultrasound measurements in three dimensions ( length ,breath and height) & multiply what you get with factor of 0.5 = Volume.
B. Surface area. Just multiple length & breath of the lesion to give you approximate surface area.
