A Systematic Review of the Variability of Ventilation Defect Percent Generated From Hyperpolarized Noble Gas Pulmonary Magnetic Resonance Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Hyperpolarized (HP) gas pulmonary MR ventilation images are typically quantified using ventilation defect percent (VDP); however, the test‐retest variability of VDP has not been systematically established in multi‐center trials. Herein, we perform a systematic review of the test‐retest literature on the variability of VDP, and similar metrics,

Functional Pulmonary Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The aging of the world population gave rise to an increased prevalence of many lung diseases, with chronic obstructive pulmonary disease now ranking as the third‐leading cause of death according to the World Health Organization. To diagnose lung disease, a thorough assessment of lung function is essential since it may reveal unique signatures ...

Magnetic Resonance Imaging in the Clinical Evaluation of Lung Disorders: Current Status and Future Prospects

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The low proton density and high signal decay rate of pulmonary tissue have previously hampered the application of magnetic resonance imaging (MRI) in the clinical evaluation of lung disorders. With the continuing technical advances in scanners, coils, pulse sequences, and image postprocessing, pulmonary MRI can provide structural and ...

MRI Assessment of Lung Water Density in Individuals Previously Infected With COVID‐19: A Cross‐Sectional Study

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Lung damage in post‐acute COVID‐19 is a common clinical finding. Lung water density (LWD) imaging using ultrashort echo time (UTE) MRI with proton‐density weighting is sensitive to edema and fibrosis. Purpose To characterize LWD in COVID‐19 survivors, compared with a healthy cohort. Study Type Retrospective cohort.
