Summary

This prospective study aims to perform intra-individual comparison of the image quality between low dose liver CT with deep learning reconstruction and standard dose liver CT with iterative reconstruction in patients with liver metastasis.

Conditions

• Liver Metastases

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	contrast-enhanced abdomen CT	contrast-enhanced abdomen CT using dual-source CT scanner using A-tube (67% radiation) and B-tube (33% radiation). * full dose CT data (A +B tubes, 100%) are reconstructed with iterative reconstruction (conventional) * low dose CT data (A-tube only, B-tube only) are reconstructed with deep learning commercially available software. * images are reconstructed using full dose (A- \& B- tubes) and smaller dose (A-tube only, B-tube only)
