Accuracy of contrast enhanced CT portal venous phase alone compare with multiphase for follow up liver metastases of various primary malignancies

Completed

• Conditions: To study an accuracy of contrast enhanced CT portal venous phase alone compare with multiphase for follow up liver metastases of various primary malignancies; CT scan venous phase, 3-phases CT scan, metastatic liver disease, liver metastases

• Registration Number: TCTR20220627005
• Lead Sponsor: /A

Brief Summary

For isolate-lesion group, PVP had the highest performance to detect metastatic lesion and highest conspicuousity (90.2%, 221 lesions) followed by HAP (26.5%, 65 lesions). Similar findings were noted in overall-lesion group, PVP had the highest detection rate of 85.1% (57 patients) followed by HAP (10 patients, 14.9%) while NECT and SP showed no superiority over the other phases in lesion detection. About one-third of breast cancer patients had better visualized lesions in HAP than PVP.
