Lung MRI


Con­tact: Hanna Frantz, M. Sc. (Phy­sics) ✉

Lung ima­ging by MRI is in par­ti­cu­lar dif­fi­cult due to low signal-​to-noise ratio (SNR) cau­sed by low pro­ton den­sity and rapid signal decay, and by car­diac and respi­ra­tory motion. In this con­text, we deve­lop new methods for:

  • self gating methods to track respi­ra­tory movements, cor­rect motion arti­facts and improve image qua­lity

  • func­tio­nal ima­ging of the lung, with and wit­hout con­trast agent
