Visual evaluation scheme and grading scale for dark-field chest radiographs and conventional x-rays. In dark-field (a) and conventional (b) chest x-ray, lungs are divided into six regions: right lung-upper zone (RL-UZ), right lung-middle zone (RL-MZ), right lung-lower zone (RL-LZ), left lung-upper zone (LL-UZ), left lung-middle zone (LL-MZ), and left lung-lower zone (LL-LZ). In each region, dark-field (a) and transmission (b) signals are visually graded using a (c) 6-point ordinate scale
