Abstract
Improved methods for providing an image of an internal region of a patient, especially the cardiovascular region. Embodiments of the invention involve the administration to the patient of a contrast agent which comprises a vesicle composition comprising lipid or polymer vesicles and a gas or gaseous precursor, in combination with a coronary vasodilator. The patient is scanned using diagnostic imaging, such as ultrasound, to obtain a visible image of the region. The methods are particularly useful for diagnosing the presence of diseased tissue in the cardiovascular region of a patient, as well as for measuring blood flow in the cardiovascular region of a patient.
