All MR examinations were performed on a 1.5-T MR system (Intera Achieva 1.5 T Pulsar, Philips Medical Systems, Netherlands) using a 16 channel head-neck coil. The three pairs of salivary glands of all patients undergone DWI before and after RT. All patients were asked not to eat or drink for at least one hour before MRI examination. The images extended from the skull base to the thoracic inlet.
Transverse DWI was obtained using a single-shot echo-planar imaging sequence with the b-value of 0 and 1000 s/mm2. DWI (TR = 4000 ms, TE = 55 ms, TI = 170 ms, matrix size = 256 × 512) were obtained with a section thickness of 6 mm and intersection gap of 1 mm, and a 180 field of view. The slice number and data acquisition time of DWI from the parotid to sublingual glands were 26 slices and 60 s. After RT, a simplified DWI protocol with the same parameters was used.
One DWI series was acquired at rest, after which 5 ml of a commercially available unsweetened 100% lemon juice (Lemondor, Italy) was injected into subjects’ mouths, and then instructed subjects to hold the juice in their mouths for exactly 10 s before swallowing. Thirty seconds after injecting the lemon juice, a set of 10 DWI were obtained with a time interval of 30 s between consecutive repeats and one minute 30 s for once sequence.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
