Brief Summary

If an abbreviated hepatobiliary phase (HBP) protocol liver MR with gadobenate dimeglumine is shown clinically comparable to standard of care liver MR with gadoxetate disodium for detecting hepatic metastasis from colorectal cancer, its use will save time, cost, and patients' effort.

Conditions

Oligometastatic Disease; Liver Metastases; Colorectal Cancer

Outcome Measures

Primary Outcomes (4)

• Preference of Radiologists for the Hepatobiliary Phase Images Generated by MultiHance (amHBP) Versus Eovist (aeHBP).

  The quality of amHBP and aeHBP images was assessed using ordinal response mixed effect models that included right/left image position as a covariate. For each paired comparison, radiologists indicated their preferred hepatobiliary phase image.

• Quantitative Timing Measures for Hepatobiliary Phase MRI

  Measures of timing used to obtain hepatobiliary phase images.

  1 month

• Estimate and Compare Quantitative Measures of HBP Images (Liver Enhancement Ratio, Lesion Contrast to Noise and Signal to Noise Ratios [CNR and SNR]) for Both Gadobenate Dimeglumine and Gadoxetate Disodium.

  A single reader analyzed paired Eovist and MultiHance hepatobiliary phase images (N=10 paired datasets). Quantitative metrics included liver-to-metastasis, liver-to-spleen, liver-to-muscle, and liver-to-blood contrast ratios (CNR's), as well as liver signal-to-noise ratio (SNR). All CNR's were calculated as signal intensity of liver relative to the reference tissue, with liver SNR liver signal/liver noise. Higher contrast ratios and higher SNR values indicate greater liver enhancement and improved lesion conspicuity.

• Estimate and Compare Qualitative Measures of HBP Images for Both Gadobenate Dimeglumine and Gadoxetate Disodium.

  A single reader performed a qualitative assessment of Dynamic and Hepatobiliary Phase Image Quality (Likert scale 1-5) for both Eovist and MultiHance Hepatobiliary Phase images (N=10 paired data). Higher scores indicate better image quality.

Study Arms (2)

Gadoxetate disodium exam first, Gadobenate Dimeglumine exam second

ACTIVE COMPARATOR

The subjects will be randomized into two groups. Both groups will undergo two complete protocol liver magnetic resonance imaging (MRI) for known or suspected colorectal cancer (CRC) metastasis, one exam with gadoxetate disodium and the other exam with gadobenate dimeglumine, within an interval of 3-20 days, but in opposite order, determined randomly.

Drug: Gadoxetate disodium; Drug: Gadobenate dimeglumine

Gadobenate Dimeglumine exam first, Gadoxetate disodium exam second

EXPERIMENTAL

The subjects will be randomized into two groups. Both groups will undergo two complete protocol liver MRI for known or suspected CRC metastasis, one exam with gadoxetate disodium and the other exam with gadobenate dimeglumine, within an interval of 3-20 days, but in opposite order, determined randomly.

Drug: Gadoxetate disodium; Drug: Gadobenate dimeglumine

Interventions

Gadoxetate disodium DRUG

Gadoxetate disodium MR contrast is now mainly used for the purpose of HBP liver MR imaging to save MR scanner time and total examination time.

Also known as: Primovist, Eovist

Gadobenate Dimeglumine exam first, Gadoxetate disodium exam second; Gadoxetate disodium exam first, Gadobenate Dimeglumine exam second

Gadobenate dimeglumine DRUG

The most commonly used MR contrast agent in abdominal imaging is gadobenate dimeglumine, which has mainly the characteristics of an extracellular agent used for most indications of MR examinations.

Also known as: MultiHance

Gadobenate Dimeglumine exam first, Gadoxetate disodium exam second; Gadoxetate disodium exam first, Gadobenate Dimeglumine exam second

Limitations and Caveats

A limitation of this study was the inability to randomize all participants due to clinical scheduling constraints. In cases where participants were already scheduled for a standard-of-care scan (gadoxetate disodium), canceling the existing appointment to allow for randomization and rescheduling within the protocol-specified window would have resulted in delays to routine clinical care

Model Details: This is a prospective study. The subjects will be randomized into two groups. Both groups will undergo two complete protocol liver MRs for known or suspected colorectal cancer (CRC) metastasis, one exam with gadoxetate disodium and the other exam with gadobenate dimeglumine, within an interval of 3-20 days, but in opposite order, determined randomly. From the complete protocol liver MR with both contrast agents, an image set of abbreviated HBP protocol liver MR for each agent will be obtained (Fig.1).Two week-intervals will be placed between the evaluations of different image sets of a patient, and the images will be presented in a different random order to each evaluating radiologist. The schedule of random order of protocol liver MRs and presentation of images to radiologists will be determined by the project biostatistician.
