Application of liver-specific contrast agents for evaluation of focal liver lesions – Expert recommendations from the Gastrointestinal and Abdominal Imaging Workgroup of the German Roentgen Society

Abstract

Purpose

Contrast-enhanced MRI is the imaging modality of choice for the detection and differential diagnosis of focal liver lesions. Liver-specific contrast agents (CAs) are now well established in addition to extracellular contrast agents. However, there is a lack of explicit recommendations reflecting the pros and cons of each specific contrast agent in the daily routine.

Materials and Methods

Development of recommendations for the clinical application of liver-specific CAs by members of the Gastrointestinal and Abdominal Imaging Workgroup within the Germany Radiological Society, using methodology comparable to that of an S1 guideline with informal consensus. The diagnostic criteria for the evaluation of liver lesions are intentionally outside the scope of this article, as there are already plenty of excellent publications available.

Results and Conclusion

The application of liver-specific CAs in the daily routine is associated with advantages and disadvantages due to the specific pharmacokinetic and pharmacodynamic properties and necessitates adjustment of the imaging technique as well consideration during image interpretation. Recommendations for the application of liver-specific CAs are presented based on different clinical scenarios, taking into account current evidence and guidelines.

Key points

• Both liver-specific and extracellular contrast agents are established

• Liver-specific contrast agents make it possible to draw conclusions about the hepatocellular function of a lesion

• Recommendations for the use of liver-specific contrast agents in the daily routine are presented
