中文摘要 | 磁振造影(成像)是一種非侵入性也不含強輻射波的安全造影法,另一優點是可取任何角度或切面來造影,不像其他造影法受到我們人體形狀之限制,雖然價格昂貴,但瑕不掩瑜,自發明以來至今卅多年已有了長足的發展。磁振造影也深植人心,是受到大眾信賴的診斷工具,甚至也開始應用到疾病預防上。本文簡明的指出磁振造影的原理,它和坊間X光及超音波造影的區隔,然後就其組成要件:造影方法、磁場、線圈以及最新應用略加敘述,以達到推廣之目的。 |
英文摘要 | Magnetic resonance imaging (MRI) is a non-invasive imaging method which does not involve radiation. Unlike other imaging modalities which are restricted by the shape and geometry of the human body and the instruments, MRI can achieve any desired orientation of sectional views. The research and development efforts put in this field over more than three decades have proven that the invaluable wealth of information derived from MRI far compensated for its cost. It is now a widely accepted and trusted diagnostic modality and is trotting on its way to the field of preventive medical practice. Here we give, in layman’s language, a brief introduction about its basic principles, major components, magnetic field, probes, and how it differs from X-ray CT and ultrasound devices. The article is targeted to the general public. |
