Query: Did you miss it? Automatic lung nodule detection combined with gaze
  information improves radiologists' screening performance   Early diagnosis of lung cancer via computed tomography can significantly
reduce the morbidity and mortality rates associated with the pathology.
However, search lung nodules is a high complexity task, which affects the
success of screening programs. Whilst computer-aided detection systems can be
used as second observers, they may bias radiologists and introduce significant
time overheads. With this in mind, this study assesses the potential of using
gaze information for integrating automatic detection systems in the clinical
practice. For that purpose, 4 radiologists were asked to annotate 20 scans from
a public dataset while being monitored by an eye tracker device and an
automatic lung nodule detection system was developed. Our results show that
radiologists follow a similar search routine and tend to have lower fixation
periods in regions where finding errors occur. The overall detection
sensitivity of the specialists was 0.67$\pm$0.07, whereas the system achieved
0.69. Combining the annotations of one radiologist with the automatic system
significantly improves the detection performance to similar levels of two
annotators. Likewise, combining the findings of radiologist with the detection
algorithm only for low fixation regions still significantly improves the
detection sensitivity without increasing the number of false-positives. The
combination of the automatic system with the gaze information allows to
mitigate possible errors of the radiologist without some of the issues usually
associated with automatic detection system.
