Model-based Bayesian inference of the ventilation distribution in patients with cystic fibrosis from multiple breath washout, with comparison to ventilation MRI

Autor: Whitfield, C.A., Horsley, A., Jensen, O.E., Horn, F.C., Collier, G.J., Smith, L.J., Wild, J.M.

Background\ud \ud Indices of ventilation heterogeneity (VH) from multiple breath washout (MBW) have been shown to correlate well with VH indices derived from hyperpolarised gas ventilation MRI. Here we report the prediction of ventilation distributio

Comparison of 3He and129Xe MRI for evaluation of lung microstructure and ventilation at 1.5T

Autor: Stewart, N.J., Chan, H.-F., Hughes, P.J.C., Horn, F.C., Norquay, G., Rao, M., Yates, D.P., Ireland, R.H., Hatton, M.Q., Tahir, B.A., Ford, P., Swift, A.J., Lawson, R., Marshall, H., Collier, G.J., Wild, J.M.

BACKGROUND: To support translational lung MRI research with hyperpolarized129Xe gas, comprehensive evaluation of derived quantitative lung function measures against established measures from3He MRI is required. Few comparative studies have been perfo

Supine posture changes lung volumes and increases ventilation heterogeneity in cystic fibrosis

Autor: Smith, L.J., Macleod, K.A., Collier, G.J., Horn, F.C., Sheridan, H., Aldag, I., Taylor, C.J., Cunningham, S., Wild, J.M., Horsley, A.

INTRODUCTION: Lung Clearance Index (LCI) is recognised as an early marker of cystic fibrosis (CF) lung disease. The effect of posture on LCI however is important when considering longitudinal measurements from infancy and when comparing LCI to imagin

Regional ventilation changes in the lung: Treatment response mapping by using hyperpolarized gas MR imaging as a quantitative biomarker

Autor: Horn, F.C., Marshall, H., Collier, G.J., Kay, R., Siddiqui, S., Brightling, C.E., Parra-Robles, J., Wild, J.M.

Purpose: To assess the magnitude of regional response to respiratory therapeutics in the lungs using Treatment Response Mapping (TRM) with hyperpolarized gas MRI. TRM is used to quantify regional physiological response in asthmatic adults using a bro
