[Abstract] Objective: To compare display performances of the 3.0 T MRI for the IDEAL, 3D-FIESTA-c, and STIR sequences of the brachial plexas, and optimize the best scanning solution.Materials and Methods: 20 healthy volunteers were recruited and underwent bilateral brachial plexus MR scan coronally through MRI, including IDEAL sequence as well as comparative 3D-FIESTA-csequence and STIR sequence. SNR and CNR of the three sequences were compared respectively by subjective observation and objective measurements.Results: IDEAL sequence has stable and reliable fat suppression effect, and can obtain multiple contrasts. Compared with the STIR sequence, images displayed by the IDEAL sequences for the postganglionic segment of the brachial plexus has higher SNR and tissue contrast against the surrounding nerves, and the images of nerves are clearer and more accurate. However, displayed images for the preganglionic nerves a little weaker in sharpness and contrast compared with the 3D-FIESTA-c sequence, but it still meets the diagnostic requirements.Conclusion: IDEAL can be used as a substitute scanning sequence of the brachial plexus to replace the STIR and 3D-FIESTA-c sequences.
