Purpose To measure the apparent diffusion coefficient (ADC) of hyperpolarized (HP) 3He
gas using diffusion weighted MRI in healthy volunteers and patients with emphysema and …

Purpose To characterize the effect of diffusion time on short‐range hyperpolarized 3He
magnetic resonance imaging (MRI) diffusion measurements across a wide range of …

PURPOSE: To quantitatively evaluate hyperpolarized helium 3 (3He) diffusion magnetic
resonance (MR) images of the lung in patients with emphysema and to determine whether …

Diffusion MRI of hyperpolarized 3He shows that the apparent diffusion coefficient (ADC) of
3He gas is highly restricted in the normal lung and becomes nearly unrestricted in severe …

PURPOSE: To compare apparent diffusion coefficient (ADC) measurements from
hyperpolarized (HP) helium (3He)-magnetic resonance imaging (MRI) with quantitative data …

Purpose To determine the reproducibility of several parameters of the ADC measurement by
calculating the scan‐to‐scan intrasubject variability. Materials and Methods Measurements …

Several studies have reported apparent diffusion coefficient (ADC) values of 3He gas in the
lung, however few have explored the dependence of these ADC values on the effective …

Purpose To measure the apparent diffusion coefficient (ADC) after inhalation of
hyperpolarized 3He in healthy volunteers and lung transplant recipients, and demonstrate …

Although the apparent diffusion coefficient (ADC) of 3He has been measured in the human
lung [1, 2, 3], no studies have determined the reproducibility of ADC values. Since the ADC …

Abstract Hyperpolarized 3He (HP 3He) MRI shows promise to assess structural and
functional pulmonary parameters in a sensitive, regional, and noninvasive way. Structural …
