Comparison Between LDCT With DL Recontruction and Standard Dose CT

Comparison of Low Dose Contrast Enhanced Abdominal CT With Deep Learning Reconstruction With Standard Dose CT With Iterative Reconstruction in Patients With Suspected Liver Metastases: A Prospective Multicenter Study

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.

Inclusion Criteria:

• patients with underlying malignancy and suspicion of liver metastasis
• patients with known liver metastasis and on follow-up
• AND scheduled for contrast enhanced abdomen CT
• signed informed consent

Exclusion Criteria:

• absolute or relative contra-indication for contrast-enhanced CT
• diffuse infiltrative liver lesion or multiple (> 10) metastases
