QCT measurements show a faster decline with aging. Therefore, the "T-score" decreases to a greater extent than DEXA, and the "T-score" is not comparable to the T-score with DEXA, as shown on this chart of QCT T-scores.
The first thing I did was obtain a DEXA, shown above, which was average for her age. The total hip was normal, and the spine T-score was -1.8. You can imagine how happy the patient and her family were to hear this news.
