MODULE 4
Basic clinical sequences, tissue contrast and image quality
Fritz Schick, Tübingen/DE

• Short recapitulation: spins, magnetization, RF excitation, relaxation
• Contrast: proton density, T1 and T2 weighting
• Cartesian spatial encoding
• Gradient echo and spin echo
• Fast spin echo / fast gradient echo sequences
• Steady state free precession
• Image quality issues
• Main artifacts
