Abstract

Magnetic resonance tomography (MRT) has advanced to be an important pillar of radiological diagnostics, along side of x-rays and ultrasound. In the present work, the technical requirements for carrying out modern MRT diagnostics are discussed as are the principles of locally generated signal registration. Typical problems in the use of MRT as well as strategies for improving image quality and for the correct interpretation of the images are detailed. Consideration is also given to how existing image problems can be eliminated by the adjustment of the in put parameters.

摘要

磁共振断层扫描(MRT)已发展成为放射诊断学的重要支柱,与X射线和超声并驾齐驱。在本研究中,讨论了进行现代MRT诊断的技术要求以及局部产生信号记录的原理。详细阐述了MRT使用中的典型问题以及提高图像质量和正确解读图像的策略。还考虑了如何通过调整输入参数来消除现有的图像问题。
