Rates of missed pathologies depend on work experience of the respective radiologists. Thus the aim of this study is to analyze the eye movements of professionals while reading CT images in order to evaluate whether the eye-fixation patterns and search strategies of experienced radiologists could explain higher detection rates of pathologies and whether such patterns can be learned.<\/jats:p><jats:p>Anonymized images of 10 patients were presented to three medical students and six radiologists with different levels of work experience. During image analysis, ocular fixation positions were recorded using an eye-tracking software tool. The CT scans were analyzed retrospectively, considering the individual course of disease with the issue of successful detection of all pathologies. Visual attention and dwell time of ocular fixation on clinically important abnormalities or areas with pathological findings, general search patterns, and time efficiency were assessed. For statistical analysis, interobserver variability and accuracy of lesion detection were evaluated taking into account individual experience.<\/jats:p><jats:p>The results revealed that observer sensitivity depends on work experience due to a more systematic order of inspection and a well-known course of disease, e.g. in case of metastatic spread. The areas of missed pathologies mostly included secondary findings. Inexperienced readers changed the stratification considerably more often and required more time for reporting or detecting pathologies.<\/jats:p><jats:p>Our results suggest that experienced radiological physicians reduce their amount of missed findings by looking more systematically at images and by applying a more targeted inspection of clinically important regions.<\/jats:p>","DOI":"10.1055\/a-2452-2180","type":"journal-article","created":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T18:54:12Z","timestamp":1731437652000},"page":"1077-1087","source":"Crossref","is-referenced-by-count":0,"title":["Different Evaluation Strategies of Oncological CT Examinations with Regard to Professional Experience: A Clinical Study Using Eye-tracking"],"prefix":"10.1055","volume":"197","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0387-702X","authenticated-orcid":false,"given":"Sara","family":"Kluge","sequence":"additional","affiliation":[{"name":"Institute of Neuroradiology, Hospital of the Goethe University Frankfurt, Frankfurt am Main, Germany"},{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"Sch\u00fclke","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hannah Christin","family":"Ites","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tarek","family":"Zoubi","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cornelia L.A.","family":"Dewald","sequence":"additional","affiliation":[{"name":"Institute of Diagnostic and Interventional Radiology, Hannover Medical School, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6562-280X","authenticated-orcid":false,"given":"Walter","family":"Heindel","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Boris","family":"Buerke","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2798-9344","authenticated-orcid":false,"given":"Anna Janina","family":"H\u00f6ink","sequence":"additional","affiliation":[{"name":"Klinikum Lippe, Department of Diagnostic and Interventional Radiology, Bielefeld University, Medical School and University Medical Center OWL, Detmold, Germany"},{"name":"Department of Radiology, University Hospital M\u00fcnster, M\u00fcnster, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,11,12]]},"reference":[{"volume-title":"Types of Eye Movements and Their Functions","year":"2001","author":"DAG Purves","key":"ref1"},{"issue":"09","key":"ref3","doi-asserted-by":"publisher","first-page":"836","DOI":"10.1055\/a-0826-5056","article-title":"Impact of Working Experience on Image Perception and Image Evaluation Approaches in Stroke Imaging: Results of an Eye-Tracking Study","volume":"191","author":"S Kammerer","year":"2019","journal-title":"Fortschr R\u00f6ntgenstr"},{"issue":"06","key":"ref4","first-page":"329","article-title":"The importance of perception research in medical imaging","volume":"18","author":"EA Krupinski","year":"2000","journal-title":"Radiation medicine"},{"issue":"01","key":"ref5","doi-asserted-by":"publisher","first-page":"140","DOI":"10.1097\/01.rct.0000151188.72850.0d","article-title":"Dose reduction in multislice computed tomography","volume":"29","author":"W Hundt","year":"2005","journal-title":"Journal of computer assisted tomography"},{"issue":"937","key":"ref6","doi-asserted-by":"publisher","first-page":"62","DOI":"10.1259\/bjr\/50019934","article-title":"Assessment of tube current modulation in pelvic CT","volume":"79","author":"GR Iball","year":"2006","journal-title":"The British journal of radiology"},{"issue":"03","key":"ref7","doi-asserted-by":"publisher","first-page":"669","DOI":"10.1007\/s00330-014-3446-9","article-title":"Abdominal and pelvic CT: is positive enteric contrast still necessary?
