Despite the unchanged retention of the fundamental technical and physical principles since its first clinical application in the year 1972, computed tomography (CT) constitutes a mainstay of present day radiological diagnostics. In conjunction with the sub-second gantry rotation times now achieved numerous technical improvements, such as helical scanning and the development of high-performance X-ray tubes as well as multi-row detectors with up to 320 rows allow large areas to be examined with high image quality within only a few seconds. On the basis of these advancements modern multidetector-row CT (MDCT) enables high-resolution slice or volume imaging of the anatomy as well as multiphase and perfusion examinations. An end to innovations in the field of MDCT is not yet foreseeable and further technical developments will open up new radiodiagnostic indications thereby broadening the spectrum of clinical applications of MDCT in the future.
尽管自1972年首次临床应用以来，计算机断层扫描（CT）的基本技术和物理原理保持不变，但它仍是当今放射诊断的支柱。结合目前实现的亚秒级机架旋转时间，众多技术改进，如螺旋扫描、高性能X射线管的开发以及多达320排的多排探测器，使得在短短几秒钟内就能以高图像质量检查大面积区域。基于这些进步，现代多排探测器CT（MDCT）能够对解剖结构进行高分辨率切片或容积成像以及多期和灌注检查。MDCT领域的创新尚未可预见，进一步的技术发展将开辟新的放射诊断适应症，从而在未来拓宽MDCT的临床应用范围。
