MRI has become a useful instrument to investigate movement patterns in the vocal tract during singing. In our study we present a new method to acquire and reconstruct images of the vocal tract during singing with an improved temporal resolution. We compare images from a Cartesian gradient echo sequence with images acquired with a radial gradient echo sequence. Data is reconstructed using a SENSE-like conjugated gradient method with low resolution sensitivity maps that are subsequently reconstructed directly from the echoes.
