Feasibility Study of MRI Imaging on Parotid Gland Stimulation

NCT02294838 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 10

Last updated 2016-11-28

No results posted yet for this study

Summary

The aim of this study is to determine the feasibility of demonstrating the following physiologically-descriptive quantities ('metrics'): the volume of plasma/volume of tissue (νp), Apparent Diffusion Coefficient (ADC), the volume of extracellular extravascular space per volume of tissue (νe), and the contrast agent transfer coefficients (Ktrans) pre and post parotid stimulation in 10 healthy volunteers. Feasibility will be defined as 80% of volunteers achieving detectable signal changes in pre/post salivary MR images.

Conditions

  • Parotid Neoplasms

Interventions

DEVICE

MRI

Participants will undergo MR imaging of the parotid gland pre and post stimulation. Perfusion images will be acquired using a time-resolved, spoiled GE sequence with 1×1×2 mm spatial resolution, approximately one second 3D temporal resolution, and image technique/contrast parameters TR = 2.8 ms and TE = 0.9 ms.

OTHER

Citric acid

5 mls of 2% citric Acid will be delivered to the oral cavity via a syringe and Tygon tubing at two separate time intervals in order to stimulate the parotid gland during the MRI scanning process.

OTHER

Gadovist

Upon commencement of the scan, 0.05 ml/kg of Gadovist (at 4 ml/s) and 20 ml of saline flush (also at 4 ml/s) will be administered.
