This research study is designed to investigate the approaches to noninvasive detection and assessment of coronary vascular dysfunction in women by comparing the testing results from the invasive standard care diagnostic procedure Angiogram and from the additional noninvasive diagnostic procedure CMR Imaging. The investigators want to specifically study 375 female patients who have signs or symptoms suggestive of heart disease but don't have obstructive coronary artery disease. Two study sites (Cedars-Sinai Medical Center and University of Florida) are recruiting participants.
