Which option is NOT a main site used for DEXA?

Explanation:
DEXA bone density testing targets sites that best reflect fracture risk and allow consistent tracking over time. The hip and spine are the main, standard sites because changes there closely mirror overall osteoporosis risk and have strong prediction for clinically significant fractures. The wrists (forearm) are often used as an additional or alternative site when hip or spine imaging isn’t feasible, providing useful information in certain patients. Knees, on the other hand, are not a routine main site for DEXA assessments, so imaging the knee isn’t part of the standard protocol.
