This study shows tumor blood flow (TBF) can be noninvasively measured using pseudo continuous arterial spin labeling in patients with head and neck squamous cell carcinoma. TBF can be useful information for estimation of prognosis and early detection of treatment effect. Moreover, TBF are considered as more sensitive indicator to determine treatment effect than conventional tumor volume measurement.
