Comparison of conventional single echo and multi-echo sequences with a fast spin-echo sequence for quantitative T2 mapping: Application to the prostate
The accuracy of water T2 maps generated from a fast spin‐echo (FSE) sequence was compared with data obtained by conventional single and multi‐echo spin‐echo pulse sequences using a commercial gel phantom. Spatially localized stimulated echo acquisition mode (STEAM) proton spectroscopy was also used...

| description | The accuracy of water T2 maps generated from a fast spin‐echo (FSE) sequence was compared with data obtained by conventional single and multi‐echo spin‐echo pulse sequences using a commercial gel phantom. Spatially localized stimulated echo acquisition mode (STEAM) proton spectroscopy was also used to confirm the reported water T2 values of the gels contained in the phantom. The FSE sequence was shown to be superior in accuracy to both the single and multi‐echo spin echo sequences and comparable to STEAM, producing results that were within 10% of known values. The effectiveness of the FSE sequence was further demonstrated by generating T2 maps of the normal and diseased prostate in clinically acceptable imaging times, resulting in comparable T2 values to those obtained using STEAM. Accurate quantitative T2 maps can be produced with the FSE sequence. |
