The quantitative evaluation of brain hemodynamics and metabolism, particularly the
relationship between brain function and oxygen utilization, is important for the …

Lung diseases have a high prevalence amongst the world population and their early
diagnosis has been pointed out to be key for successful treatment. However, there is still a …

The 3He lung morphometry technique, based on MRI measurements of hyperpolarized 3He
gas diffusion in lung airspaces, provides unique information on the lung microstructure at the …

MRI-based study of 3He gas diffusion in lungs may provide important information on lung
microstructure. Lung acinar airways can be described in terms of cylinders covered with …

Despite decades of research into the mechanisms of lung inflation and deflation, there is
little consensus about whether lung inflation occurs due to the recruitment of new alveoli or …

Purpose To quantitatively characterize early emphysematous changes in the lung
microstructure of current and former smokers with noninvasive helium 3 (3He) lung …

Objectives To evaluate repeatability of intravoxel incoherent motion (IVIM) diffusion-
weighted imaging (DWI) parameters in the orbit. Methods From December 2015 to March …

The progressive decline of lung function with aging is associated with changes in lung
structure at all levels, from conducting airways to acinar airways (alveolar ducts and sacs) …

Purpose To demonstrate the feasibility of compressed sensing (CS) to accelerate the
acquisition of hyperpolarized (HP) 129Xe multi‐b diffusion MRI for quantitative assessments …

Rationale Hyperpolarized (HP) 129Xe‐MRI provides non‐invasive methods to quantify lung
function and structure, with the 129Xe apparent diffusion coefficient (ADC) being a well …
