Abstract:
1. A method for producing an image of a subject with a magnetic resonance imaging (MRI) system the steps comprising: a) acquiring, with the MRI system reference image data using a first pulse sequence that saturates a selected labile spin species by applying a radiofrequency (RF) irradiation at a reference frequency, b) acquiring, with the MRI system, labeled image data using a second pulse sequence that saturates a selected labile spin species by applying an RF irradiation at a labeling frequency; c) reconstructing a reference image from the acquired reference image data and a labeled image from the acquired labeled image data; and d) producing a corrected ratio image by subtracting the reconstructed labeled image form the reference image to correct for relaxation-induced losses by recovering saturation of the selected labile spin species.
