Ultra-short echo time (UTE) MRI was already shown to be appropriate for the quantification of the peribronchovascular inflammation typical of the first phase of the chosen ovalbumin model of asthma. The high quality of the images indicated the possibility of extending the protocol until the last phases of the model, in order to assess also the remodeling associated with the disease.
