No statistically significant difference existed between the datasets for the visibility and sharpness scores of any other segment for each reader (P > 0.05 for both readers).
Comparison of assigned visibility and sharpness scores between SSFP MRA and CE-MRA for both readers using the Mann-Whitney U-test revealed significantly higher visibility scores for the aortic root (annulus, sinus of Valsalva, and sino-tubular junction) on SSFP MRA compared with CE-MRA (P < 0.001 for both readers).
We also introduce the probabilistic performance measures sharpness, reliability and interval skill score for model comparison and for checking the reliability of the confidence bounds.
However, when using PIT as a diagnostic tool it has to be considered that PIT does not take into account the sharpness of the density forecast, as opposed to proper scoring rules providing a combined assessment of both calibration and sharpness simultaneously.
But it is the way that he scores — with predatory sharpness, elusive movement, and brave athletic ability — that makes him so coveted.
Indicators including the distortion rate (DR), marginal calibration, sharpness, and the continuous ranked probability score (CRPS) are applied to evaluate the distribution forecast performance of the proposed approach.
Match sharpness, particularly when it comes to scoring goals, is very important.
Image quality score, contrast-to-noise ratio, sharpness index, coefficient of variation (CV), and measured defect size were assessed as measures of image quality.
An optimal imaging setting would be one that provides high image quality score, contrast-to-noise ratio, sharpness index, and low CV.
