Assessing How Normal Variations in CT Scanning Affects Its Interpretation
Sponsor: Memorial Sloan Kettering Cancer Center
Summary
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.

CT scan
Patients with colorectal liver metastases scheduled for abdominopelvic CECT will be consented to undergo an additional CT of their abdomen (termed add-on CT) within 15 seconds, before or after, their clinical portal venous phase CT (PV CT), which is performed at a fixed delay of 80 seconds at our institution.
