FIG 4. T1-weighted and fat-suppressed T2-weighted MR imaging features of the parotid glands correlated well with conventional sialographic features. The horizontal bar indicates mean; small circles, outliers.
A, Graph shows a high correlation between fat areas as assessed on T1-weighted MR images and conventional sialographic grades (G0–G4).
B, Graph shows a high correlation between intact lobule area as assessed on fat-suppressed T2-weighted MR images and conventional sialographic grades (G0–G4).
