What are your thoughts on the newer flexible RF coils?
MR vendors have come up with higher density flexible coils replacing the traditional rigid body coils. Only the head coil is still in rigid form. GE calls them AIR Technology™ Coils, Siemens version is called BioMatrix Contour Coils and Philips calls them SmartFit coils.
From what I gathered, these coils are very flexible, able to wrap tightly around any region of interest with minimal distance between the target area and the antenna. They also feature higher density of sensor elements closely packed together. As a result they claim to feature improved** **Signal-to-Noise Ratio (SNR) because they sit closer to the anatomy,
What are the real-world advantages of these newer RF coils in practice?
