Optimal timing of MR sialography by use of a simple method of stimulating the salivary gland: a preliminary report.
The present study was performed for determining the optimal timing of MR sialography by use of the Japanese pickled plum (umeboshi) for promoting secretion by the salivary glands. MR sialography was performed in four healthy male volunteers. The four volunteers were examined before and 10 min after stimulation with umeboshi. On the next examination, three volunteers were examined before and after umeboshi stimulation every 1 min up to 5 min to allow assessment of the temporal changes in duct visualization. Dilatation of the salivary gland ducts and improvement of the visualization of the ducts were obtained after stimulation with umeboshi. The difference in the dilatation of the parotid duct was statistically significant. In the temporal study, the salivary gland ducts were shown to be dilated at 2 min after stimulation. As a result, 2 min after stimulation is the optimal timing for MR sialography by use of umeboshi as a stimulator of salivary secretion.
