Wireless array for SNR enhancement in small animal MRI at 5T

Key Points

The wireless array significantly improved SNR, allowing for clearer imaging in small animal MRI.
Achieved imaging resolution of 0.2 mm × 0.2 mm × 0.5 mm using the wireless coil in a 5T system.
The experimental setup involved comparing a custom wireless array to a rat coil for performance.
Results support the use of wireless RF coils in enhancing imaging capabilities for small animals.

Abstract

Motivation: Clinical MRI scanners lack sufficient SNR for high-resolution small animal imaging, limiting research on diseases. Goal(s): Design a compact, wireless array to improve SNR and enable high-resolution imaging in small animal MRI at 5T. Approach: In this study, we made a wireless array and compared its imaging performance with the rat coil. Results: The wireless coil achieved high-resolution imaging of up to 0.2 mm × 0.2 mm × 0.5 mm in the 5T system. Impact: The experiment demonstrated the potential of wireless RF coils for high-resolution imaging in small animal MRI.
