Method and system for performing upright magnetic resonance imaging of various anatomical and physiological conditions

Abstract:

Vasculature or parenchyma is imaged using upright MRI techniques, on patients who may have conditions such as congestive heart failure, or otherwise be healthy. When an individual is horizontal, venous drainage is minimized, causing the vessels to remain engorged, also referred to herein as vascular congestion. Vascular congestion results in an enlarging of the vessels and surrounding tissue causing the vessels to be more visible on MRIs. The decrease in vascular visibility in upright subjects is in part, due to an increase in venous drainage. Patients suffering from coronary and/or pulmonary deficiencies (e.g. CHF) experience decreased rates and degrees of venous drainage. In one embodiment, the present invention uses upright imaging to visualize these enlarged vessels.
