Cardiovascular applications of magnetic resonance flow and velocity measurements

With recent developments of MR techniques for blood now measurements, qualitative and quantitative information on both now volume and pow velocity in the major vessels can be obtained, MR now quantitation uses the phase, rather than the amplitude of the MR signal, to reconstruct the images. Previous validation studies have demonstrated the accuracy of the phase shift techniques for measuring now velocities. This technique is now being applied successfully in the cardiovascular system to quantify global and regional ventricular function, valvular heart disease, pulmonary artery disease, thoracic aortic disease, congenital heart disease, and ischemic heart disease.
