Abstract MRI with hyperpolarized helium‐3 (3He) provides high‐resolution imaging of
ventilated airspaces. The first aim of this 3He‐study was to compare observations of …

Magnetic resonance imaging (MRI) using hyperpolarized 3helium (He) gas as the source of
signal provides new physiological insights into the structure–function relationships of the …

The purpose of this study was to describe the 3He MRI findings of normal pulmonary
ventilation in healthy volunteers and to evaluate abnormalities in patients with different lung …

We applied the rapid imaging capability of echo planar MR pulse sequences and
hyperpolarized 3He ventilation imaging to observe the dynamic distribution of gas in the …

Abstract 3 He magnetic resonance imaging (MRI) is capable of producing new and regional
information on normal and abnormal lung ventilation. The basis of 3 He MRI involves …

Purpose To evaluate the use of spin‐tagging in conjunction with hyperpolarized gas
imaging for monitoring lung ventilation and gas diffusion. Methods and Materials Images …

MRI of the lungs using hyperpolarized helium‐3 (3He) allows the determination of
intrapulmonary oxygen partial pressures (pO2). The need to separate competing processes …

Traditional magnetic resonance imaging (MRI) uses the NMR signal from protons to obtain
images in the human body. The technique enables detailed imaging of brain and soft tissue …

Images of hyperpolarized 3He were acquired during breath‐hold in four healthy volunteers
with the use of an optimized 3D gradient‐echo sequence. The images were compared with …

During the past several years there has been extensive development and application of
hyperpolarized helium‐3 (HP 3He) magnetic resonance imaging (MRI) in clinical respiratory …
