Abstract: A method placing a gas into a first cavity of a patient, where the gas includes hyperpolarized 3-Helium (3-He). At least a portion of the patient is imaged using MRI to detect the gas within the patient. Based at least in part on the imaging, a determination is made regarding whether at least a portion of the gas is present in a second cavity of the patient. Presence of the gas in the second cavity is indicative of a leakage of the first cavity.
