An improved decision support system for abnormal brain mass discrimination using MRS - INTERPRET 3.0
...
Pérez Ruiz, Alexander | 2009
The DSS has been improved progressively since the end of the INTERPRET project [1,2]. Version 3.0 includes several new features with respect to version 2.0, among them: three new classifiers, user profiles and an embedded database for storing new user cases. The new classifiers are:
- A new LDA classifier using concatenated short and long echo time spectra
[3]. Figure.
- A ratios plot CHO/NAA at long TE vs MI/NAA at short TE which may be
used as a tumour-pseudotumour classifier [4].
- An LDA classifier with short TE spectra for discrimination of tumoural
and pseudotumoural brain masses.
Version 3.0 is able to store user profiles for various features like background
colours and case notes. Users may share these notes with other users of the
same clinical centre with a common installation. The user may also track
notes of each case using its input date and the user login information.
The “load new case” process has been simplified. The case to be loaded can
have one or two spectra at different echo times and they can be loaded simultaneously into the DSS. New cases can be permanently stored into the embedded data base if the user wishes so. New cases can also be complemented with MRI and additional clinical information.
