Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA),as a hepatobiliary specific contrast agent,plays an increasingly important role in magnetic resonance imaging(MRI)of focal hepatic lesions.This study reviewed the application status and latest progress of Gd-EOB-DTPA enhanced MRI technology in early detection,accurate diagnosis and evaluation of response to treatment of colorectal liver metastases(CRLM).The introduction of Gd-EOB-DTPA significantly improved the detection sensitivity of CRLM,especially in small lesions with a diameter of less than 1 cm.In addition,radiomics based on Gd-EOB-DTPA enhanced MRI provides a new perspective for the evaluation of CRLM and assists clinical decision making through quantitative analysis of image features.This paper summarizes the specific image features and advantages of Gd-EOB-DTPA enhanced MRI in the diagnosis and treatment of CRLM,which provides a scientific basis for further optimizing patient management and guiding treatment strategies.
