AbstractThe parotid gland function is evaluated by gustatory stimulation using scintigraphy in clinic. It is supposed to measure the water component of parotid gland using PD MRI instead of scintigraphy. In this study, we initially developed the evaluation of parotid gland function by PD MRI, and 10 healthy volunteers underwent double echo EPI with gustatory stimulation. Maximal drop ratio (MDR), time to peak (TTP), drop slope (DS), recovery slope (RS) and recovery ratio (RR) were calculated. The signal intensity dropped significantly after gustatory stimulation on PD image (P<0.01). MRI allows quantification of parotid gland function using semi-quantitative functional parameters.
