I use imhist(). Is your ROI rectangular, or free form? Let me know if you want a demo.

Hi Image Analyst. Can I have a linear ROI instead of a freehand one for this code? And also, is there a way to compare the intensity values of 2 similar roi with a histogram at the same time? Thank you! Your code has helped me greatly.

If ROImask is a logical mask for the ROI, you can do
histc(yourImage(ROImask),...)
