MRS434 Magnetic Resonance Imaging (8)

This subject introduces and familiarises the students with the imaging modality of magnetic resonance imaging (MRI). It covers the MRI physics and instrumentation, detailed examination of pulse sequences, scan techniques and protocols utilised in clinical practice. It also considers quality assurance, magnetic and RF safety issues and departmental planning.
