P03277—A New Approach to Achieve High-Contrast Enhancement

Abstract

This study provides the first in vivo and in vitro data of P03277, an experimental extracellular MR contrast agent. P03277 demonstrates significantly better enhancement properties as compared with gadobutrol in experimental hepatic colorectal cancer metastases. In addition, in vitro data demonstrate superior relaxivities of P03277 at a broad spectrum of different field strengths. Hence, this new agent has the potential to improve lesion conspicuity and subsequently sensitivity in diagnostic imaging for both clinical magnetic resonance imaging at 1.5 or 3 T and ultra-high field applications between 4.7 and 9.4 T.
