Assessing How Normal Variations in CT Scanning Affects Its Interpretation

Stability of Radiomic Features for Abdominal Tumors on Contrast Enhanced CT

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.

Conditions

• Colorectal Cancer Metastatic

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	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.
