Described here are a system and method for obtaining multiple different images when performing a single scan of a subject with a magnetic resonance imaging ('MRI') system. The scan includes the application of two or more magnetization preparation radio frequency ('RF') pulses, such as inversion recovery (&#x201c;IR&#x201d;) pulses. Data is acquired after the application of each magnetization preparation RF pulse, thus allowing the acquisition of multiple different images of the subject in a single scan. Using this approach, the same information that used to require multiple different scans of the subject can be acquired in one single scan, and in less time than would be required to perform the multiple scans.

MRI double inversion recovery method and system, with different magnetization recovery states providing the MRI image contrast(s)

Described here are a system and method for obtaining a time series of images that depict a subject using an inversion recovery ('IR') pulse sequence with a unique data acquisition scheme that allows for the retrospective identification of an image having an optimal tissue contrast. Data acquisition is performed using a radial acquisition scheme such as, preferably, a vastly undersampled isotropic projection reconstruction ('VIPR') scheme. Using VIPR and IR, combined with a unique projection ordering, a series of three-dimensional, high spatial resolution images with multiple different image contrasts can be obtained.
