DGML semi-quantitative scale.

<p><b>A</b>. No lesion; <b>B</b>. Punctuate lesion; <b>C</b>. Lesion involving less than 1/3^rd of the nucleus. <b>D</b>. Lesion involving between 1/3^rd and 2/3^rd of the nucleus. <b>E</b>. Lesion of more than 2/3^rd of the nucleus. <b>F</b>. Total involvement of the nucleus.</p

Cross validation (Jacknife test).

<p>In each validation test, we used data from all but one subject (S -1 of the S subjects) to train the classifier.</p

Example of a satisfactory registration of the DGM on a T2 FSE axial slice passing through the thalami (delineated in green) and striatum (delineated in blue).

<p>Note the punctuate lesion involving the left thalamus (arrow).</p

Receiver operating characteristic (ROC) curves and area under the curve (AUCs) for the different grading scales used in this studies, alone or in combination, with or without the factor “age” taken into account.

<p>Note that the AUC of the ROC curve of the DGM nuclei grading scale was higher than the one of the other scores, alone or combined, with or without the age.</p
