Qamar S, et al. - Experts ascertained whether or not the treatment of nasopharyngeal carcinoma (NPC) induces early changes in amide proton transfer-weighted (APTw) magnetic resonance imaging (MRI). They also performed a preliminary evaluation of APTw imaging in response assessment. Findings suggested the probability of the detection of APT value changes in early intra-treatment. They noted the potential of intra-treatment %Δ APT_mean in predicting short-term outcome.
