Fast-Spin-Echo CNR data and scanning parameters comparison analysis.

<p>Fast-spin-echo T1-weighted (FSET1) brain parenchyma-tumor mean CNR graphical representation. In pre-contrast conditions: graphs A_1,3,5) and A_2,4,₆) report respectively in vivo and simulated CNR FSET1 data when changing ESP, ETL, TR and NSA (the scan time was limited to 5 minutes). In post-contrast conditions: graphs B₁,₃) and B₂,₄) reported respectively in vivo and simulated CNR FSET1 data when changing ESP, TR and NSA (the scan time was limited to 5 minutes). Black arrows point at selected parameters that typically coincide with the highest CNR providing the <i>“optimal in vivo scanning parameters”</i> for the in vivo method, and the “<i>optimal computed scanning parameters</i>” with the simulated approach. The latter parameters are compared by the “Scanning parameters comparison analysis” and the outcome reported as successful (YES) or failing (NO). Note that although the graphs are related to a single mouse dataset, they are a good representation of the entire animal cohort.
