摘要:

磁共振成像(MRI)是一种强大的非侵入式生物医学诊断技术. 临床上, MRI需要借助造影剂来提高成像质量, 从而提高诊断的准确性. 由于具有优越的信号放大能力和生物相容性, 自组装多肽探针可负载特定的MRI分子, 通过酶促自组装过程实现肿瘤靶向和特异性富集, 增强肿瘤病灶区MRI信号, 从而进一步提高MRI的准确性和灵敏度. 本综述总结了近年来多肽自组装探针在不同MRI模式( 1H MRI, 19F MRI和双自旋核MRI)下的最新进展, 并展望了这类新型探针在MRI领域的应用前景.

Abstract:

Magnetic resonance imaging(MRI) is a powerful non-invasive biomedical diagnostic technique. Clinically, MRI requires contrast agents to improve imaging quality, thereby improving the diagnosis accuracy. Due to the superior signal amplification ability and biocompatibility, self-assembled peptide probes can be loaded with specific MRI molecules to achieve tumor targeting and enriching through the enzyme responsive self-assembly process. Thus, self-assembled peptide probes can enhance the MRI signal of tumor lesions, thereby further improving the accuracy and sensitivity of MRI. This review summarizes the recent progress of self-assembled peptide probes under different MRI modalities( 1H MRI, 19F MRI, dual nuclei MRI), and highlights their potential for cancer diagnosis.

Key words: Self-assembled polypeptide, Enzyme responsive MRI probe, 1H MRI, 19F MRI, Tumor imaging
