  Enhanced spectral shaping in steady‐state free precession imaging

  , Magnetic Resonance in Medicine, Vol: 58, Pages: 1216-1223, ISSN: 0740-3194

  <jats:title>Abstract</jats:title><jats:p>Balanced steady‐state free precession (SSFP) is hindered by the inherent off‐resonance sensitivity and unwanted bright fat signal. Multiple‐acquisition SSFP combination methods, where multiple datasets with different fixed RF phase increments are acquired, have been used for shaping the SSFP spectrum to solve both problems. We present a new combination method (weighted‐combination SSFP or WC‐SSFP) that preserves SSFP contrast and enables banding‐reduction and fat‐water separation. Methods addressing the banding artifact have focused on either getting robust banding‐reduction (complex‐sum SSFP) or improved SNR efficiency (sum‐of‐squares SSFP). The proposed method achieves both robust banding‐reduction and an SNR efficiency close to that of the sum‐of‐squares method. A drawback of fat suppression methods that create a broad stop‐band around the fat resonance is the wedge shape of the stop‐band leading to imperfect suppression. WC‐SSFP improves the suppression of the stop‐band without affecting the pass‐band performance, and prevents fat signal from obscuring the tissues of interest in the presence of considerable resonant frequency variations. The method further facilitates the use of SSFP imaging by providing a control parameter to adjust the level of banding‐reduction or fat suppression to application‐specific needs.

  Fluid‐attenuated inversion‐recovery SSFP imaging

  <jats:title>Abstract</jats:title><jats:sec><jats:title>Purpose</jats:title><jats:p>To describe and evaluate a fast, fluid‐suppressed 2D multislice steady‐state free precession (SSFP) neuroimaging sequence.</jats:p></jats:sec><jats:sec><jats:title>Materials and Methods</jats:title><jats:p>We developed a fast fluid‐attenuated inversion‐recovery SSFP sequence for use in neuroimaging. The inversion time (TI) was optimized to yield good cerebrospinal fluid (CSF) suppression while conserving white matter (WM)/lesion contrast across a broad range of flip angles. Multiple SSFP acquisitions were combined using the sum‐of‐squares (SOS) method to maximize SNR efficiency while minimizing SSFP banding artifacts. We compared our fluid‐attenuated inversion‐recovery (FLAIR) SSFP sequence with FLAIR fast spin‐echo (FSE) in both normal subjects and a volunteer with multiple sclerosis. SNR measurements were performed to ascertain the SNR efficiency of each sequence.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Our FLAIR SSFP sequence demonstrated excellent CSF suppression and good gray matter (GM)/WM contrast. Coverage of the entire brain (5‐mm slices, 24‐cm FOV, 256 × 192 matrix) was achieved with FLAIR SSFP in less than half the scan time of a corresponding FLAIR FSE sequence with similar SNR, yielding improvements of more than 50% in SNR efficiency. Axial scans of a volunteer with multiple sclerosis show clearly visible plaques and very good visualization of brain parenchyma.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>We have demonstrated the feasibility of a very fast fluid‐suppressed neuroimaging technique using SSFP.
