1. A method for evaluating a gastrointestinal tract of a subject, the method comprising:
positioning a sensor in a lumen of the gastrointestinal tract using a medical delivery device;
using the sensor positioned in the subject to obtain data regarding qualities of a tissue of the gastrointestinal tract;
using the obtained data, determining, by one or more processors in communication with the medical delivery device, a measure of perfusion of blood in the tissue;
using the obtained data, determining, by the one or more processors, a measure of thickness of the tissue;
using the measure of perfusion and the measure of thickness, determining, by the one or more processors, a measure of inflammation of the tissue; and
using one or more of the measure of perfusion, the measure of thickness, and the measure of inflammation, classifying, by the one or more processors, a state of the tissue.
