Array of representative images of a HNSCC patient with partial response after
treatment. Images in each row are from three measurement time points:
pretreatment (A), 1 week after radiation therapy (B), and 2 weeks after the
completion of the treatment (C). Large arrows, same metastatic
nodal mass that was followed through the treatment course; small
arrow, central region of the mass with ADC higher than the rim.
