Abstract: The present disclosure discloses a method for synthesizing high-quality magnetic resonance images, wherein the method expands the value ranges of echo time TE and repetition time TR in a magnetic resonance signal formula to negative intervals, and expands the contribution of proton density PD to a negative power. The method can effectively reduce the influence of the measurement error of quantitative magnetic resonance imaging tissue parameters on the tissue contrast of the synthetic magnetic resonance image, and can obviously improve the tissue contrast of the synthetic magnetic resonance image. This method will significantly improve the imaging quality of synthetic magnetic resonance imaging, and promote its detection effect in neuroscience and clinical lesions. This method is expected to improve the imaging quality of synthetic magnetic resonance imaging and promote its detection effect in neuroscience and clinical lesions.

Abstract: The invention provides substantially pure abductin protein and polypeptides, polypeptides composed of multiple repeats of the glycine-rich repeat sequences of abductin, and hybrid polypeptides containing an abductin polypeptide linked to another protein or polypeptide, e.g., an elastin or fibroin (silk) polypeptide, as well as nucleic acids encoding these polypeptides. The abductin polypeptides and their derivatives can be used in the manufacture of a broad range of biomaterials ranging from light-weight durable fabric for clothing to matrices useful for human tissue and organ prostheses.
