Overall Recruitment Status Withdrawn no participants

This trial studies how well a magnetic resonance imaging technique called Displacement Encoding with Stimulated Echo (DENSE) works in detecting chemotherapy-related liver injury in patients with colorectal cancer that has spread to the liver and can be removed by surgery. Researchers want to learn if the DENSE technique improves the standard MRI method.

PRIMARY OBJECTIVE:

I. This is an exploratory study to collect Magnetic Resonance Displacement Encoding with Stimulated Echo (MR DENSE) imaging data of patients treated with chemotherapy prior to resection of metastases to explore its utility in detecting sinusoidal liver injury.

SECONDARY OBJECTIVES:

I. Estimate sensitivity of MR DENSE (determine degree of 2 dimensional [2D] vector displacement with cardiac cycle and variability of measurements with cardiac ventricle contraction).

II. Determine detection of sinusoidal injury (sinusoidal fibrosis, necrosis of pericentral hepatocytes, narrowing and fibrosis of central veins) on biopsy with non-alignment of 2D point vectors (horizontal and vertical direction) from neighboring/immediate adjacent points on MR DENSE imaging.

III. Determine correlation of intra-operative surgical scores (liver color and texture) with non-alignment of 2D point vectors (horizontal and vertical direction) from neighboring/immediate adjacent points on MR DENSE imaging.

OUTLINE:

Patients undergo standard of care magnetic resonance imaging (MRI) and then undergo an MRI of the liver using MR DENSE imaging sequences over 60-90 minutes. Healthy volunteers undergo MRI of the liver using DENSE imaging sequences.

Inclusion Criteria:

• Patients treated with neoadjuvant chemotherapy and scheduled for hepatectomy, per standard of care at our institution, and meet criteria for hepatectomy.
• No contraindications to MRI (such implanted ferromagnetic or pump devices, metallic fragments in eye), as indicated on our departmental MRI screening form.
• Patient who is able to undergo informed consent.
• Men and non-pregnant women.
• Metastatic disease limited to liver.
• Metastases involving no more than 6 liver segments.
• No radiographic evidence of involvement of the hepatic artery, major bile ducts, main portal vein, celiac/para aortic lymph nodes.

Exclusion Criteria:

• Contraindication to MRI.
• Inability to comply with study and/or follow-up procedures.
• Unable to provide informed consent.
• Presence of extrahepatic metastatic disease.
• Metastases involving more than 6 liver segments.
• Radiographic evidence of involvement of the hepatic artery, major bile ducts, main portal vein, celiac/para aortic lymph nodes.
• Pregnant women.
