Pulmonary ventilation visualized using hyperpolarized helium-3 and xenon-129 magnetic resonance imaging: differences in COPD and relationship to emphysema.
In subjects with chronic obstructive pulmonary disease (COPD), hyperpolarized xenon-129 ((129)Xe) magnetic resonance imaging (MRI) reveals significantly greater ventilation defects than hyperpolarized helium-3 ((3)He) MRI. The physiological and/or morphological determinants of ventilation defects and the differences observed between hyperpolarized (3)He and (129)Xe MRI are not yet understood. H...
متن کامل3D Hyperpolarized (129)Xe MRI of mouse lung at low xenon concentration using a continuous flow-type hyperpolarizing system: feasibility for quantitative measurement of regional ventilation.
PURPOSE We investigated the feasibility of 3D hyperpolarized (HP) (129)Xe magnetic resonance (MR) imaging at an extremely low concentration of HP (129)Xe supplied from a continuous flow-type hyperpolarizing (CF-HP) system and established a standard procedure for measuring regional lung ventilation of small animals, such as the mouse, as a baseline for further studies. MATERIALS AND METHODS We...
متن کاملMine the moon for 3He MRI? Not yet.
THE PULMONARY IMAGING COMMUNITY was abuzz recently with the acute shortage of He, brought about by a more than 10-fold increase in demand from the US Department of Homeland Security, a demand increase more than 10-fold the annual supply (2). Public and privately funded pulmonary MRI projects ground to a screeching halt (in addition to those involving low-temperature physics and neutron detectio...
متن کاملUsing Free-breathing Proton Ventilation MRI to Evaluate Treatment Response in Asthma
Purpose: Hyperpolarized noble gas magnetic resonance imaging (MRI) provides a way to map both functional and structural pulmonary information. Specifically in asthmatics, inhaled hyperpolarized gas MRI has been used to evaluate bronchoconstriction (methacholine-challenge [MCh]) and bronchodilation (salbutamol), showing ventilation defects that respond to MCh and salbutamol [1]. Fourier decompos...
متن کاملMultiple breath washout of hyperpolarized 129Xe and 3He in human lungs with three‐dimensional balanced steady‐state free‐precession imaging
PURPOSE To compare quantitative fractional ventilation measurements from multiple breath washout imaging (MBW-I) using hyperpolarized 3 He with both spoiled gradient echo (SPGR) and balanced steady-state free precession (bSSFP) three-dimensional (3D) pulse sequences and to evaluate the feasibility of MBW-I with hyperpolarized 129 Xe. METHODS Seven healthy subjects were scanned using 3 He MBW-...
