Indirect detection of lung perfusion using susceptibility-based hyperpolarized gas imaging.


PURPOSE To address the problem of inadequate signal-to-noise ratio (SNR) encountered in lung perfusion magnetic resonance imaging (MRI) by developing an indirect detection based on the strong hyperpolarized (HP) gas signal. MATERIALS AND METHODS Our model is based on detecting the effects of gadolinium (Gd) flowing through lung capillaries by recording… (More)
