Because of the high signal-to-noise (S/N) ratio, T2-weighted images obtained using high-field magnetic resonance (MR) imaging systems can be expected to provide high anatomical and contrast resolution. Furthermore, the improved structural and contrast resolution of these high S/N T2-weighted images can be processed for optimum perceptual resolution through the application of gray-scale reversal and expansion of the gray-scale window, known as T2-reversed (T2R) imaging. In this study, the authors investigated high-resolution T2R MR imaging performed on a high-field (3-tesla) system for its clinical utility in detecting various physiological and pathological conditions.
由于高信噪比(S/N),使用高场磁共振(MR)成像系统获得的T2加权图像有望提供高解剖分辨率和对比度分辨率。此外,通过应用灰度反转和灰度窗口扩展(称为T2反转(T2R)成像),可以对这些高信噪比T2加权图像的改进结构和对比度分辨率进行处理,以实现最佳感知分辨率。在本研究中,作者研究了在高场(3特斯拉)系统上进行的高分辨率T2R MR成像在检测各种生理和病理状况方面的临床应用。
