To demonstrate the range of gains and losses that radiologists might experience from independent double reading in screening mammography.
From a national random sample of radiologists, the authors formed 131 pairs. For each radiologist, the authors analyzed the increase relative to his or her individual true-positive rate (TPR) or false-positive rate (FPR), number of additional cancers detected, and change to negative biopsy rate that would result from independent double reading after pairing.
The average radiologist can expect an 8%-14% gain in TPR and a 4%-10% increase in FPR with pairing. For some radiologists, double reading increased the TPR with a small concomitant increase in FPR. Other radiologists, however, realized small gains in TPR with large increases in FPR. Adding the reading from a more experienced radiologist did not necessarily improve the TPR of a radiologist with less experience.
Radiologists can form complementary and noncomplementary pairs for double reading. Use of this procedure must be decided on an individual basis.
证明放射科医生在乳腺钼靶筛查中进行独立双人阅片可能经历的收益和损失范围。
作者从全国放射科医生随机样本中组成131对。对于每位放射科医生，作者分析了相对于其个人真阳性率（TPR）或假阳性率（FPR）的增加、额外检测到的癌症数量，以及配对后独立双人阅片导致的阴性活检率变化。
平均而言，配对后放射科医生的TPR可提高8%-14%，FPR提高4%-10%。对于一些放射科医生，双人阅片在略微增加FPR的同时提高了TPR。然而，其他放射科医生TPR提高幅度较小，而FPR大幅增加。增加一位经验更丰富的放射科医生的阅片不一定能提高经验较少的放射科医生的TPR。
放射科医生在双人阅片中可形成互补和非互补配对。此程序的使用必须根据个人情况决定。
