- 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 |
