What is mri phase contrast?

MRI phase contrast imaging is a technique used to measure blood flow and velocity in living tissues. By using the phase shift of the MRI signal caused by the motion of protons in flowing blood, this technique can provide quantitative measurements of blood flow velocity and direction. Phase contrast MRI has been found useful in diagnosing and monitoring a wide range of conditions, including cardiovascular diseases, cerebral ischemia, and cancer. It is a non-invasive imaging technique and does not expose the patient to ionizing radiation, making it safe for repeated assessments over time. However, the technique requires specialized MRI equipment and skilled technicians to perform and interpret the results.
