ABSTRACT:
A contrast agent is administered to a patient by inhalation into the patient's lungs. The agent is transmitted through the lungs into the patient's bloodstream, for transport to a non-lung portion of the patient to be imaged. A portion of the patient containing the microbubbles is subjected to an ultrasound scan, so as to obtain an enhanced ultrasonically generated image of the patient.
