Abstract

Systems and methods for magnetic resonance imaging (“MRI”) using a frequency swept excitation that utilizes multiple sidebands to achieve significant increases in excitation and acquisition bandwidth are provided. The imaging sequence efficiently uses transmitter power and has increased sensitivity as compared to other techniques used for imaging of fast relaxing spins. Additionally, the imaging sequence can provide information about both fast and slow relaxing spins in a single scan. These features are advantageous for numerous MRI applications, including musculoskeletal imaging, other medical imaging applications, and imaging materials.
