060713140 MAGNETIC RESONANCE IMAGING ( 3 Crd.Hrs )

Describe the Nuclear Magnetic Resonance (NMR) phenomenon, the significance and the uniqueness of the Larmor frequency for a nuclear species, the origin of the T1 and T2 relaxation mechanisms, the behavior of T1 and T2 as the strength of the static field is changed, Describe the spin-echo and inversion recovery pulse sequences – including multiple spin echo and STIR. Outline the advantages and characteristic features of Gradient Echo, Fast Spin Echo, Echo Planar Imaging (EPI) and other fast imaging techniques. Image formation, the main parameters that affects on image quality (spatial resolution; contrast resolution and signal to noise ratio (SNR)). The main imaging protocols used in MRI imaging includes the imaging of head and neck, spine, chest, abdomen, pelvis, lower limbs, and upper limbs. On the other hand, the basic knowledge of the vascular imaging protocols will be provided to the student. Discuss safety issues (patient and environmental) and contra-indications in the use of MRI.
