The use of magnetic resonance imaging, in the demonstration of internal human anatomy and in the diagnosis of disease, has the major advantages that the technique is noninvasive, does not require the use of ionizing radiation and that it can demonstrate neurological and cardiovascular lesions that cannot be diagnosed easily by other imaging methods. Magnetic resonance imaging is derived from the principle that certain atomic nuclei in a strong magnetic field will absorb pulses of radiofrequency energy; when the pulse is finished the nuclei will emit radiowaves at the same frequency. These radiowaves are received by specially designed aerials or coils and the information is collected by a computer which reconstructs an image of internal anatomy in a similar way to that of x-ray computed tomography (CT). By changing the strength of the magnetic fields and the frequency of the radiowave pulses, it is possible to examine different sections within the body. The first magnetic resonance images of humans were obtained in Australia in October 1985 on the research instrument of the Queensland Medical Magnetic Resonance Research Centre, which is based at the Mater Hospital in Brisbane, and is part of the University of Queensland's Department of Radiology.
磁共振成像在展示人体内部解剖结构和疾病诊断方面具有主要优势，即该技术是非侵入性的，不需要使用电离辐射，并且能够显示出其他成像方法难以诊断的神经和心血管病变。磁共振成像源于这样一个原理：在强磁场中某些原子核会吸收射频能量脉冲；当脉冲结束时，原子核会以相同频率发射无线电波。这些无线电波由专门设计的天线或线圈接收，信息由计算机收集，计算机以类似于X射线计算机断层扫描（CT）的方式重建内部解剖结构的图像。通过改变磁场强度和无线电波脉冲频率，可以检查身体内的不同部位。1985年10月，在澳大利亚昆士兰医学磁共振研究中心的研究仪器上获得了第一批人体磁共振图像，该研究中心位于布里斯班的圣母医院，是昆士兰大学放射学系的一部分。
