腦物質定量分析軟體

The LCModel package isfor the automatic quantitation of in vivo proton MR spec tra. LCMgui isa graphical user interface for running LCModel with more con venience and lessknowledge of thismanual. LCMgui isprovided without charge for use with LCModel only.
LCMgui Graphical User Interface
The normal usage is to supply the time-domain data as a simple text file to LCModel. A possible alternative is the LCMgui graphical user interface:
•    Freely available for use with LCModel. 

 
•    Simplified usage, often only with mouse clicks, in two steps:
1.    Select the data with the File Selector; 
 
2.    Start LCModel (optionally checking and modifying any settings) in the Control Window.

 
•    Currently for the following single-voxel data:
o    Bruker ParaVision fid files (if necessary, converted by you to analog mode with Bruker's convdta). 
 
o    GE 5.x Probe raw P-files and spectrum G-files. 
 
o    GE Probe raw P-files, including (new) Signa 20 P-files. Also for P-files with multi-channel (phased-array) data. 
 
o    Hitachi data: part of the Hitachi software; no need to purchase separately. 
 
o    Philips SDAT & SPAR files. 
 
o    Picker (later Marconi, now Philips) DUMP files. 
 
o    Siemens *rda files transferred from the syngo PC console and Siemens raw files from the (old) Numaris-3 Unix console. 
 
o    Toshiba rawData files and Version 7.xx (and later) DICOM files; 
 
o    Varian fid files; 
 
o    Other data types using your own conversion script.

 
    Currently for the following MRSI data:
o    Bruker (analog mode), Philips, Siemens & Toshiba data, including interactive display, selection and analysis of full 2D slices or rectangular subsets. (Instructions in Sec. 3.6 of the LCModel Manual.) 
 
o    Other data types using your own conversion script; 
 
o     For GE MRSI (and single-voxel) data, Mary McLean's LCModel interface [MA McLean et al, Magn Reson Med 44, 401 (2000)] is integrated into GE's SAGE Research version (from SAGE Dev2002.1). 
 
Features:
•    Fully automatic, non-interactive, operator-independent: time-domain data input, one-page summary output.
•    Fully developed, over 17 years, with spectra analyzed from a wide variety of scanners and field strengths at more than 500 sites. 
 

Application:
  •  Automatic quantification of in vivo proton MR spectra.

  • Some early user applications of LCModel can be seen in the sample publications list .


News:
LCModel Version 6.3 (free upgrade for current LCModel sites):
  •  Estimation of GABA with MEGA-PRESS.
  •  Improved estimation of weaker metabolites, especially glutamine.
  •  Improved analyses of muscle, lipid, breast and liver spectra.

Past News:
LCModel Version 6.2. While the main application remains brain
 ,options have been added for more primitive spectra:
  •  Mainly water & lipids, as in fat and bone marrow.
  •  Water & lipids plus possibly choline, as inbreast and liver.
  •  LCModel Version 6.1 with new options, including analysis of muscle spectra, particularly for IMCL.
  •  A Linux version for PCs (with Intel or AMD processors) is now available. It is much faster than UNIX, with an excellent hardw       are performance/price ratio, particularly interesting for MRSI.
  •  In Japan, you obtain LCModel (and support) directly from the exclusive LCModel distributor for Japan, L.A. Systems,
     http://www.las.jp.
  •  Major new LCModel Version 6 with many new features, including:
  •  Estimates of macromolecule and lipid contributions in normals and in pathologies (e.g., tumors) with strong lipid signals
      and without strong lipid signals.
  •  Analyses of full 2D slices or rectangular 2D subsets of 2D or 3D MRSI data sets.

Features:
  •  Fully automatic, non-interactive, operator-independent: time-domain data input, one-page summary output.
  •  Fully developed, over 26 years, with spectra analyzed from a wide variety of scanners and field strengths at more than 1000 sites.


Download, Install & Test:
  •  You can freely download the complete LCMgui/LCModel package for your Linux PC. (The two commands needed for
      installation and the run with the test data are also specified.) You can also test the preparation and input of your own
      data to LCModel.
  •  You can fully enable your LCModel package to analyze all data (not just the test data) with a license.


Methods are described in:
  •  Stephen Provencher: Estimation of metabolite concentrations from localized in vivo proton NMR spectra. Magn Reson Med 30, 672 (1993).
  •  User's Manual (you can always get the latest version here).
