Semiautomatic Segmentation of Ventilated Airspaces in Healthy and Asthmatic Subjects Using Hyperpolarized (3)He MRI

A segmentation algorithm to isolate areas of ventilation from hyperpolarized helium-3 magnetic resonance imaging (HP (3)He MRI) is described. The algorithm was tested with HP (3)He MRI data from four healthy and six asthmatic subjects. Ventilated lung volume (VLV) measured using our semiautomated te...
