MRI of hyperpolarized He-3 gas in human paranasal sinuses
Type of Work
Magnetic Resonance in Medicine
In this study, MRI of hyperpolarized He-3 gas in human paranasal sinuses is presented, Helium images were obtained at 1.5 T, using a surface coil and a 2D, fast gradient-echo sequence with a nominal constant flip angle of 12 degrees, Coronal images of 20-mm thick slices were generated and compared with proton images of the corresponding sections. The images enable visualization of the paranasal sinuses and the nasal cavity, suggesting a potential use of this method not only in identifying the anatomical configuration of these pneumatic spaces, but also in assessing sinus ventilation.
