Eovist® (gadoxetate disodium) injection
Eovist® is a gadolinium-based MRI-contrast agent approved for intravenous use in magnetic resonance imaging (MRI) of the liver to detect and characterize lesions in patients with known or suspected focal liver disease.
Eovist® Overview and Characteristics
See the value of functional information
In addition to dynamic-phase imaging, Eovist® Injection offers additional morphological and functional information about lesion cell composition. Compared with pre-contrast MRI, MRI with Eovist® increases liver-to-lesion contrast during the hepatocyte phase.1,2
Like extracellular GBCA, Eovist® provides morphological and vascular information.
Eovist® allows for intracellular hepatocyte phase imaging approximately 20 minutes after injection.1,2
Bolus injection of Eovist®
Eovist® distributes rapidly into the extracellular space.
50% of the Eovist® dose is selectively taken up by functioning hepatocytes.
- Eovist® is equally eliminated via renal and hepatobiliary systems in patients with normal renal and liver function
- If one of the pathways is impaired, Eovist® can still be eliminated without significant pharmacokinetic or pharmacodynamic changes, except in patients with end-stage renal failure (ESRF)
- Severe hepatic impairment or ESRF may impair Eovist® imaging performance
Eovist® Clinical Pharmacology Video
See how Eovist® is distributed into the extracellular space after bolus injection and selectively taken up by functioning hepatocytes due to its lipophilic (EOB) moiety.
Demonstrated safety profile in clinical trials
- Overall 4.3% of subjects reported one or more reactions during a follow-up period that for most subjects, extended 24 hours after Eovist® administration. The adverse reactions were predominately of mild to moderate severity.3
- The most frequent (≥0.5%) adverse reactions associated with the use of Eovist® are nausea, headache, feeling hot, dizziness and back pain.3

In clinical trials, Eovist®-enhanced MRI demonstrated improved lesion detection, as compared with pre-contrast MRI:
- Significant improvement in detection of metastases and hepatocellular carcinoma1
- 12% more small metastases (<1 cm in diameter) detected1*
*Standard of Reference (SOR): surgical specimen and/or intraoperative US (IOUS)
Diagnosis: Small liver metastases
Next step: Scheduled hepatectomy cancelled
In clinical trials, as compared with pre-contrast MRI, Eovist®-enhanced MRI demonstrated:
- Improved lesion classification of benign vs malignant1,2*
- Improved lesion characterization by 12% (96% with Eovist®-enhanced MRI vs. 84% with unenhanced MRI, p=0.0002)4
*SOR: histopathology and/or IOUS and/or long-term imaging follow up.
- Focal nodular hyperplasia (FNH)
- Hepatocellular carcinoma (HCC)
Diagnosis: FNH and → Adenoma
Next step: Follow-up imaging (6 months later)
In clinical trials, as compared with pre-contrast MRI, Eovist®-enhanced MRI improved diagnostic confidence and accuracy:
- High confidence of lesion characterization: 92% vs 63%2*
- Improved the accuracy of classification of benign vs malignant lesions from 90.9% to 97.5%2
*SOR: histopathology and/or IOUS and/or long-term imaging follow up.
†Gadolinium-based contrast agent.
- Atypical FNH
Next step: Biopsy?
Diagnosis: Fibrolamellar HCC
Next step: Resection (pathology confirmed)

- Due to high relaxivity in plasma and the liver, the approved dose of Eovist® injection is 0.025 mmol/kg.1-3
The Eovist® 15 mL single-dose vial is available to conveniently dose patients weighing 220 lbs to 330 lbs.
- Quality: Maintain image quality through appropriate weight-based dosing in patients requiring >10 mL
- Minimization of waste: Use one 15 mL vial instead of two 10 mL vials
