Reporting order: Plain Film - ULDCT
Reporting order: ULDCT - Plain Film
The plain film of half the participants (randomized) will be submitted for reporting by a radiologist as a first imaging method. After finishing this report, the same radiologist will assess the ULDCT of this participant. In this second report, the findings of both examinations will be summarized, and a second report will be filed. Emergency physicians will first receive the report for the plain film of the chest and will be asked for the diagnosis and its probability. Next, the report for ULDCT will be presented to them. Again, diagnosis and probabilities will be documented.
For half the participants (randomized) radiologists will first receive the data from ULDCT of the chest and write a report. Subsequently, they will receive the data from the plain film of the chest and may expand their report (explicitly separated). Emergency physicians will first receive the report for the ULDCT of the chest and will be asked for probabilities of the nine most frequent diagnoses in chest-imaging plus "other". Next, they will be presented with the report for the plain film and will again be asked to give an estimation of the probabilities for the same diagnoses as before.
