Magnetic resonance phase shift techniques accurately measure blood flow velocities and are successfully applied to quantify cardiovascular function across various heart diseases.
With recent developments of MR techniques for blood flow measurements, qualitative and quantitative information on both flow volume and flow velocity in the major vessels can be obtained. MR flow 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 flow 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.
Szolar et al. (Mon,) conducted a review in Cardiovascular diseases. Magnetic resonance flow and velocity measurements was evaluated. Magnetic resonance phase shift techniques accurately measure blood flow velocities and are successfully applied to quantify cardiovascular function across various heart diseases.
