核磁共振成象技术是一门新兴的边沿科学技术,近十年来得到迅速发展。NMR成象设备由于其对人体没有射线的损害,由于它不但能提供与XCT相同的解剖学信息,而且能显示不同方位的动态生理生化过程及其影象、可以用于恶性肿瘤的早期诊断、急性心梗的判别,血管中血液流速的测量以至病理学、药物学、免疫学,等等广泛得多的医学领域,使得各大国争相研究这一技术。本文下面从几个方面介绍核磁共振成象技术原理,使读者对其概貌有一个初步的了解。
Magnetic resonance imaging technology is a new edge science and technology, rapid development in the past decade. Because of its no radiation damage to human body, NMR imaging equipment can not only provide the same anatomical information as XCT, but also display dynamic physiological and biochemical processes and their images in different directions, which can be used in the early diagnosis of malignant tumors, Discrimination of acute myocardial infarction, measurement of blood flow velocity in blood vessels, and much broader fields of medicine such as pathology, pharmacology, immunology, and the like have compelled major powers to study this technology. Here are several aspects of this article describes the principles of magnetic resonance imaging technology, so that readers have a preliminary overview of its profile.
