Table 2 5-point Likert scale evaluation of MRS

From: Feasibility and impact of using an automated user interface for proton spectroscopy in multiparametric MRI of the prostate

RateSaturation pulseSpectral qualityAutomatic segmentation
1Saturation pulse exactly at the marginSpectra all over the margin of the PZ of good diagnostic qualitySegmentation curve lies exactly at the margin of the prostate
2Gap between the prostate and one or more of the saturation pulsesSpectra all over the margin of the PZ are minimally distorted but still of good diagnostic qualitySegmentation curve extends beyond the prostate margin and covers parts of the peri-prostatic tissues
3One or more of the saturation pulses cover part of the PZSpectra all over the margins of the PZ are markedly distorted with poor diagnostic qualitySegmentation curve covers the prostate, but ≤ 20% of the PZ are not included
4One or more of the saturation pulses cover the whole PZ≤ 20% of the PZ pixels are distorted with poor diagnostic qualitySegmentation curve covers the prostate, but > 20% of the PZ are not included
5One or more of the saturation pulses cover the prostate completely> 20% of the PZ pixels are distorted with poor diagnostic qualitySegmentation curve totally away from the prostate (prostate not included within the curve)
