What is the difference between osteopenia, osteoporosis?

Less bone loss: Osteopenia is the term we give to the amount of bone loss that occurs in a patient with t scores between -1 and -2.5 based on the world health organization's criteria for measuring bone loss. The more negative the t score, the more bone loss has occurred. If a T-score is between 0 and -1, this bone density would still be considered normal. I hope that helped answer your qquestion.
