![]() Of a GBCA occured in 1988 and has since led It can lead to a change in theĭiagnostic work-up, differential diagnosis and Is commonly accepted in the medical–scientificĬommunity. In general, the clinical usefulness of extracellularĬontrast agents for various applications to detect or exclude a disease has been documented (Eovist ® Bayer-Schering, Berlin, Germany, synonymĭiagnostics Inc., NJ, USA) for liver MRI. , or hepatocyte-specific agents like gadoxetate Targeted MR contrast agents exist that eitherĪre blood-pool agents with a strong proteinīinding affinity for MR angiography (MRA) MRI is currently used for a wide range of clinicalĪpplications and is not limited to specificīody areas. Lesions independent of the body region under Information to classify benign and malignant No significant impact on the extracellular distribution Modify the parameters used with other GBCAs,Īs the concentration of the contrast agent has In different body regions) without the need to MRI sequences (e.g., imaging of focal disease Gadobutrol is suitable for all clinically used The case with other approved contrast agents. Various body regions other than the CNS, as is Provide similar imaging properties in conventional Ischemic and nonischemic tissue as comparedĭose.

KeywordsĬontrast-enhanced MRA ▪ contrast-enhanced MRI ▪ CNS n Gadavist ™ ▪ gadobutrol ▪ gadolinium-based contrast agent ▪ Gadovist ™ ▪ kidney ▪ liver Gadobutrol offers increased T1 relaxivity, which improves MR image quality and clinical use of the technique. Gadobutrol (1.0 mmol/ml), an extracellular macrocyclic contrast agent of high stability, is indicated for contrast-enhanced MRI of adults, adolescents and children 2 years of age and older. However, a limitation of conventional contrast agents in MRI is the insufficient signal-to-noise ratios due to relaxivity. Overview on the efficacy and safety of gadobutrol: an MRI contrast agent for the CNS, body and vessels Juan E Gutierrez * 1, Sara Koenig 1 & Josy Breuer 2Ģ Bayer-Schering AG, Berlin, Germany Corresponding Author: Juan E GutierrezĬontrast-enhanced MRI has become a mainstay of clinical imaging with unlimited applications.
