Liver metastasis

Patients with suspicion of liver metastasis and scheduled for CT

contrast-enhanced abdomen CT

Intervention Type DIAGNOSTIC_TEST

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)
