為磁振造影檢查病人做最好的準備

Optimal Preparation for Patients Undergoing Magnetic Resonance Imaging

磁振造影可應用於檢查所有組織，其檢查過程為非侵入性，沒有副作用又無游離性放射線暴露，所以被普遍的使用。但是，由於掃描腔的空間狹窄，受檢者的活動受限，機器運轉時噪音明顯，及檢查過程費時，使病患感受到不愉快的經驗，有的病人甚至無法完成檢查，影響早期的診斷與治療。本篇文章介紹磁振造影的來歷、原理、檢查前病人所需做的準備、及檢查時放鬆或降低空間恐懼症的方法，期望能協助病患安全、順利的完成檢查。

MRI can be used in all kinds of tissue. Because the process is non-invasive and free of ionization radiation, it has been widely used.
