  • 2d csi proton mr spectroscopy of human Spinal Vertebra feasibility studies
    Journal of Magnetic Resonance Imaging, 2000
    Co-Authors: Chinshoou Lin, Djamil Fertikh, Bolivia Davis, William C Lauerman, Frasier Henderson, Dieter Schellinger
    Abstract:

    This report focuses on proton magnetic resonance spectroscopy (1H MRS) of spine Vertebra acquired with two-dimensional chemical shift imaging (2D CSI), utilizing the stimulated echo acquisition mode (STEAM) sequence. Both validity and reproducibility studies were performed. To validate the 2D CSI method, its spectra were compared with those obtained with the single-voxel (SV) method. Five normal volunteers were scanned. The reproducibility of 2D CSI was examined by performing spectroscopy on two different occasions, on three normal volunteers. Data show that the STEAM 2D CSI technique results in MRI spectra comparable to those obtained with the STEAM SV method. 2D CSI offers significant time savings and convenient multi-voxel spectral analysis at a substantially higher signal-to-noise ratio. The 2D CSI method was then applied to a patient with a small Vertebral hemangioma. The results demonstrated that the voxels containing the hemangioma exhibit different spectra than the neighboring voxels of the same Vertebra. Additionally, a case of Vertebral osteoporosis was investigated. Results showed a significant increase in the lipid-to-water ratio (LWR). It is suggested that 2D CSI may be powerful in identifying physiological as well as pathological changes of the bone marrow. Furthermore, covering a more extensive area of the Vertebral body will maximize the chances of depicting a small focus of pathologic tissue. A more detailed bone marrow pattern was noticed in on one subject whose spectra show more lipid peaks. J. Magn. Reson. Imaging 2000;11:287–293. © 2000 Wiley-Liss, Inc.
