Each parameter was scored on a scale of 1 to 5. The ^aindividual parameter US-CT agreement score was defined as 5 minus the absolute difference of scores between US and CT. The higher the score, the better the agreement. 5 is the highest score, indicating indentical scores for US and CT (e.g., US = 4 and CT = 4, then US-CT agreement score = 5−|4−4| = 5; 1 is the lowest score, indicating polar opposite scores by US and CT (e.g., US = 5 and CT = 1, then US-CT agreement score = 5−|5−1| = 1).
