Is this cancer or TB to be detected, or something else?
CT scans are grayscale so you will not be able to detect anything by color.

Look for papers describing how to do that here: http://www.visionbib.com/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models or in PubMed.

What are PBRs?
Try imfreehand(), like in the attached demo, to have your expert draw the ROI.
