Abstract
Methods for providing an image of an internal region of a patient. Embodiments of the methods involve administering to the patient a contrast agent which comprises a vesicle composition comprising, in an aqueous carrier, a gas or gaseous precursor and vesicles comprising lipids, proteins or polymers. The patient is scanned using diagnostic imaging, such as ultrasound, to obtain a visible image of the region. The contrast agent is administered to the patient at a rate to substantially eliminate diagnostic artifacts in the image. The methods are particularly useful for diagnosing the presence of any diseased tissue in the patient.
