In 2006, a novel method for extracting functional ventilation-weighted lung images using
MRI was published. The method exploited the naturally occurring density changes in the …

Respiratory motion and pulsatile blood flow can generate artifacts in morphological and
functional lung imaging. Total acquisition time, and thus the achievable signal to noise ratio …

Purpose To measure regional specific ventilation with free-breathing hydrogen 1 (1H)
magnetic resonance (MR) imaging without exogenous contrast material and to investigate …

The current work is a continuation of a new MRI technique that was proposed for the non-
invasive assessment of regional lung ventilation using inhaled molecular oxygen as a T 1 …

Current indirect measurements of alveolar fluid clearance (AFC) suggest that the rate of fluid
clearance correlates with morbidity and mortality in patients with pulmonary edema. In a …

Pulmonary emphysema is a pathologic condition characterized by permanently enlarged
airspaces distal to the terminal bronchiole with destruction of the alveolar walls. Functional …

Specific ventilation imaging (SVI) is a functional magnetic resonance imaging technique
capable of quantifying specific ventilation―the ratio of the fresh gas entering a lung region …

Assessment of the pulmonary function remains a challenge for the development of suitable
MRI techniques due to the unique lung tissue structure and its short effective transverse …

Pulmonary perfusion is a fundamental parameter of lung function, since matched distribution
of the regional pulmonary blood flow (perfusion) and ventilation is a prerequisite for gas …

The global increase in asthma, chronic obstructive pulmonary disease, and other pulmonary
diseases has stimulated interest in preclinical rat models of pulmonary disease. Imaging …
