Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a study to determine whether or not a new type of software is, or is not, of benefit. The software, ClearRead Confirm, is designed to enhance the ability of radiologists to detect tubes, lines and wires that may be placed within a patients chest. These types of devices are commonly used for very sick patients in intensive care units and are also used following surgery and in the treatment of cancer. This study will test radiologist's detection of the tips of these devices comparing the results with standard chest radiographs and the the modified chest radiographs. The primary interest is in the time used to interpret the radiograph. We will determine if there is any change in accuracy of detection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary hypothesis: the amount of time used for the interpretation of these radiographs will not change. (null hypothesis)

Secondary hypothesis: there will be no change in the accuracy of the detection of the tips of venous catheters and tubes transiting the esophagus. (null hypothesis)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard chest radiographs

The radiologists will be viewing two groups of chest images. The first group are standard chest radiographs.

No interventions assigned to this group

Modified chest radiographs

This group of chest radiographs will be presented with the modified image. The modified image is intended to increase the visibility of tubes, lines and wires on chest radiographs

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* For the radiologists, they must in in active practice of community radiology (non-university sites).
* For the cases, they must be patients who have a tube, line, or wire in their chest. A small number of completely normal bedside chest radiographs will be included.
