Abstract:
After nearly 40 years of development,MRI has become an important imaging diagnostic method in clinical practice.Non-contrast enhanced MRI combined with contrast-enhanced MRI can provide multidimensional information,significantly improving lesion detectability and supporting the entire disease management cycle.With the decentralization of medical resources,contrast-enhanced MR technologies(such as magnetic resonance angiography,dynamic contrast-enhanced MRI and dynamic susceptibility contrast-enhanced MRI,etc.)have become popular in primary healthcare facilities.As a critical adjunct to contrast-enhanced imaging,high-pressure injection technology for contrast agents plays a determinant role in ensuring imaging quality and diagnostic validity.This technology offers distinct advantages in precise control of injection parameters(flow rate,dosage,timing),maintenance of bolus integrity and enhancement of inter-study reproducibility.However,the absence of standardized international and domestic guidelines for its application currently hinders the harmonization of imaging data and limits cross-institutional interoperability of diagnostic results.To address this gap,an expert group has developed the"Expert Consensus on the Application of High-Pressure Injection Technology for Magnetic Resonance Contrast Agents",referencing domestic and international guidelines and literature,and in conjunction with the current application status in the country.This consensus aims to provide radiology professionals with safe and effective technical application guidance and to promote standardized clinical practice.
