Atelectasis, often caused by a mechanical ventilator, promotes lung injury, whose mechanisms are not fully understood. Understanding these underlying mechanisms requires simultaneous measurements of ventilated air space and alveolar size, which can be achieved through the use of hyperpolarized gas MRI technology. Additionally, this technique can show how alveolar recruitment maneuvers reestablish a normal pattern of airspace inflation.
