MRI Pioneer speaks at City
City's Engineering department hosts a lecture from Professor Sir Peter Mansfield on Real time MRI: Echo-planar imaging.
The Engineering department hosted a lecture last week from Professor Sir Peter Mansfield, on Real time MRI: Echo-planar imaging. Sir Peter, a pioneer in the field of Magnetic Resonance Imaging (MRI), discussed echo-planar imaging (EPI), the snap-shot imaging technique capable of producing medically useful images in times around 50ms.
He talked about the advantages and disadvantages of EPI, as follows:
- The advantages of EPI are that rapid movies can be produced, thereby helping the diagnostic process, and rapid sequencing of images can be obtained through a region of the body corresponding to a multi-slice volume image. Single shot single slice images can be obtained thereby considerably reducing both movement artefact and the patent scan time.
- Current major disadvantages are the high acoustic noise associated with the rapid pulsing of the gradient coils, and the large electric field associated with the generation of the magnetic gradient. Both effects carry dangerous implications for patient safety.
This lecture was given as part of the Edwards Lecture Series by Professor Sir Peter Mansfield FRS, Nobel Laureate.
