摘　　要：MR成像是多参数成像的一种检查技术,其原理复杂,质量控制受多种因素制约。在实践中,以MR的成像原理、各成像参数的特点及其相互之间的制约关系为依据,以获得优质MR图像为目的进行参数优化。在硬件的安装、调试上,确保各项参数指标均在合格的范围内。在扫描技术上,对各个成像参数加以优化、组合、灵活应用。在较短的检查时间内获得优质的MR图像,为疾病的诊断提供科学的依据。Magnetic resonance imaging is a multiple parameter imaging examination technology, Its principle is complex, Quality control is conditioned by many factors. In practice, with MRI imaging principle, imaging parameters on the basis of the characteristics and the relations among each other, In order to obtain high quality magnetic resonance image for the purpose of parameter optimization. On the hardware installation, commissioning, Ensure all parameters are within the scope of the qualified. On the scanning technology, The various imaging parameters optimization, portfolio, flexible application. In a relatively short time get the high quality magnetic resonance imaging examination. Provide scientific basis ibr the diagnosis of the disease.
