Assessing How Normal Variations in CT Scanning Affects Its Interpretation (NCT03038568)
🩺 Plain-English Summary (8th-Grade Level)
The purpose of the study is to see how measurements of tumor differences vary with slight changes in CT scan parameters. Reproducible radiomic features can be extracted for abdominal tumors, and specifically colorectal liver metastases, imaged with clinical CT scanners even in the setting of variable scan parameters and variable contrast timing. Participants will be consented to undergo an additional CT of their abdomen.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (3 items) and avoid the listed exclusions (5 items).
