FIG 6. Discrepancy in imaging features of the parotid glands between MR sialography and conventional sialography.

A–J, MR sialograms (A–E) and conventional sialograms (F–J) of the parotid glands in xerostomia patients with or without Sjögren’s syndrome: grade 0 (A and F), grade 1 (B and G), grade 2 (C and H), grade 3 (D and I), and grade 4 (E and J). Note apparent differences in sialographic features at grade 4 (E versus J).
