MagniXene MRI Use in Patients With Asthma and COPD to Assess Regional Lung Function by Delineating Ventilation Defects

MagniXene (HXe) is an Investigational New Drug made of xenon noble gas. Through a physical process using alkali vapors and powerful lasers, xenon atoms have their nuclear spin preferentially aligned (hyperpolarized), thus offering a highly enhanced signal inside an MRI scanner. High-resolution images of the lung spaces are acquired within a short breath-hold after inhalation of HXe.
