Two fellowship-trained expert prostate MRI readers were tasked to contour the histologically known significant prostate cancer on the T2w sequence simulating a target volume definition for focal prostate cancer treatment.
The participants performed pitch identification using a four-choice reaction task, pitch contour perception, and pitch discrimination.
60, 61 Previous results demonstrated age-related difficulties in interpreting linguistic patterns, 56 and the performance of older adults on linguistic tasks with pitch contour patterns was less accurate than that of younger adults, ie, more difficulty identifying questions than statements.
The results of the contour task varied with age.
The scores for the contour task improved with age as previously reported.
The data for two children (one aged <5 years, another aged 6 7 years) were missing for the contour task.
17 The contour task assesses the ability to integrate information across areas of the visual field and is assumed to rely on neurons that support long-range facilitation.
We propose putative tasks whose performance contours jointly lead to the observed suite of variations, including hydrodynamic efficiency, shell economy, compactness and rapid shell growth.
We did not test monocular vision or stereopsis or exclude children with strabismus which may have lowered our observed norms for the contour task that can be abnormal in the presence of these conditions.
There were 7/214 (3.3%) for whom there was no score written for the postbox result and of these none had major problems with the rectangles and all did the contour task.
