Hyperpolarized Xenon MRI Biosensors Development Program

超极化（HP）氙磁共振（MR）成像生物传感器有可能彻底改变疾病的检测和表征，也许有一天会提供一个较低的成本补充正电子发射断层扫描（PET）作为分子成像的首选方法。MR成像生物传感器具有高空间分辨率（类似于MRI）和高灵敏度（类似于PET），而没有任何与PET相关的电离辐射。此外，氙成像生物传感器的成本明显低于PET。这种较低的成本和电离辐射的缺乏使这些成像生物传感器更有利于更频繁的成像研究。

Hyperpolarized (HP) Xenon magnetic resonance (MR) imaging biosensors have the potential to revolutionize the detection and characterization of disease and may perhaps one day provide a lower cost complement to positron emission tomography (PET) as a preferred method of molecular imaging. MR imaging biosensors have high spatial resolution (similar to MRI) with high sensitivity (similar to PET) without any of the ionizing radiation associated with PET. Additionally, xenon imaging biosensors are of significantly lower cost than PET. This lower cost and lack of ionizing radiation make these imaging biosensors more conducive to more frequent imaging studies.
