Basic Pulse Sequences for MRI[1]
Image Type TR TE Fat Signal Intensity Water Signal Intensity Advantages Disadvantages
T1 Short Short Bright Dark Best anatomic detail, rapid acquisition Poor visualisation of pathology/oedema
T2 Long Long Intermediate Bright Moderate sensitivity for pathology/oedema Poor spatial resolution, time consuming
Fat-suppressed T2 Long Short Very dark Very bright Most sensitive for pathology/oedema Susceptible to artifacts related to magnetic resonance inhomogeneity
Gradient Echo Short Short Intermediate Intermediate/high Excellent for articular cartilage, PVNS, and blood Very susceptible to metallic artifacts
Proton Density Long Short Intermediate/high Intermediate Excellent for meniscal pathology
