Expert recommendations about the use of gadoxetic acid in patients with liver metastases in Spain

Abstract

BACKGROUND AND AIMS: Magnetic resonance imaging (MRI) with gadoxetic acid is widely used in clinical practice in Spain for the diagnosis, treatment, and follow-up of patients with liver metastases, although its use varies. This paper aims to provide recommendations for the use of MRI with gadoxetic acid in the detection and diagnosis of liver metastases in clinical practice in Spain. MATERIAL AND METHODS: This project was undertaken by a group of nine experts who analyzed a series of recommendations about the use of gadoxetic acid extracted from international consensus documents. From this analysis, the experts decided to reject, adopt, contextualize, or adapt each of the recommendations. Once established, the final recommendations were voted on by the same group of experts. RESULTS: The experts reached a consensus about five recommendations related to the use of this imaging technique in the management of liver metastases in three clinical situations: (i) in the detection, (ii) in the diagnosis and preoperative characterization, and (iii) in the detection after a chemotherapy treatment. CONCLUSION: The results support a clinical benefit for MRI with gadoxetic acid in the detection of liver metastases, favoring preoperative planning, especially in metastases measuring less than 1?cm, thus facilitating early diagnosis of metastatic spread.
