A magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. The radiologist may discuss initial results of the MRI with you right after the test. Complete results are usually ready for your doctor in 1 to 2 days.
Echo planar imaging (EPI), a fast MRI technique, is used to sequentially acquire brain images every few seconds (TR = 1s - 4s) during several minutes. These images are of medium quality and prone to susceptibility artifacts, but their short acquisition time makes them ideal for fMRI acquisitions.
