Ever since the introduction of magnetic resonance (MR), imaging with 1.5 Tesla (T) has been considered the gold standard for the study of all areas of the body. Until not long ago, higher-field MR equipment was exclusively employed for research, not for clinical use. More recently, the introduction of 3.0-T MR machines for new and more sophisticated clinical applications has resulted in important benefits, especially in neuroradiology. Indeed, their high gradient power and field intensity (3.0 T) allow adjunctive and more advanced diagnostic methodologies to be performed with excellent resolution in a fraction of the acquisition time required with earlier machines. The purpose of this paper is to illustrate the distinctive semeiological characteristics of 3.0-T morphological and angiographic brain imaging compared with lower-field systems and highlight the respective advantages and drawbacks based on the experience gained in the first 5 years from the installation of a 3.0-T magnet.
自从磁共振（MR）问世以来，1.5特斯拉（T）成像一直被视为全身各部位研究的金标准。直到不久前，高场强MR设备还仅用于研究，而非临床应用。最近，3.0-T MR机器被引入用于新的、更复杂的临床应用，带来了重要益处，尤其是在神经放射学领域。事实上，其高梯度功率和场强（3.0 T）使得辅助性和更先进的诊断方法能够在比早期机器所需采集时间短得多的情况下，以出色的分辨率进行。本文旨在阐述与低场系统相比，3.0-T脑形态学和血管造影成像独特的符号学特征，并根据安装3.0-T磁体头5年所积累的经验，突出各自的优缺点。
