Figure Lengend Snippet: 2D Phase Sensitive Inversion Recovery (PSIR), 3D T1‐w, and 2D T2*‐w Protocol Parameters

Article Snippet: With regard to the GM delineation/contrast, visual qualitative assessment indicated consistent good quality for the PSIR images (23, 24, 23 for Siemens, Philips, and GE), while the quality of some of the T 2 * − w images (12 over 72, which means about 17%) was suboptimal (scores 24, 19, 23 for Siemens, Philips, and GE).

Techniques: Sequencing

Figure Lengend Snippet: PSIR images acquired at the C2‐C3 disc level for the 12 subjects on the three different scanners. Each row is a subject and from left to right: Siemens scanner test acquisition, Siemens scanner retest acquisition, Philips scanner test acquisition, Philips scanner retest acquisition, GE scanner test acquisition, and GE scanner retest acquisition. In the bottom right image an example of ROIs used for the CNR evaluation is reported.
