Hyperpolarized xenon highlights ventilation defects in MRI.

Images were taken before and after bronchodilation at each visit.

Changes in ventilation defect percentages were seen in responders at 4 weeks.

SAN FRANCISCO — Hyperpolarized xenon MRI may be useful in assessing response to biologic treatment among patients with asthma, according to a poster presented at the American Thoracic Society International Conference.

“Severe asthmatics often are treated with biologic treatments,” Gabriela Mar í a Garc í a Delgado , research student, chemical and biomedical engineering, University of Missouri, told Healio. “Some of them do respond well.”

Data were derived from Garcia Delgado GM, et al. Utilizing hyperpolarized 129Xe MRI as a biomarker for asthmatics on biol
