在九名患有颈动脉粥样硬化的受试者中，通过近端颈内动脉的粥样斑块获得了双倾斜、对比材料增强、双反转恢复、快速自旋回波磁共振 (MR) 图像。使用钆造影剂后，动脉粥样硬化斑块内的纤维细胞组织选择性增强 29%。对比度增强有助于区分纤维帽和脂质核心，其对比噪声比与 T2 加权 MR 图像一样好或更好，但信噪比大约是 T2 加权图像的两倍（对比后图像，36.6 +/- 3.6；T2 加权图像，17.5 +/- 2.1；P < .001）。 (C) 北美放射学会，2002 年。
In nine subjects With carotid atherosclerosis, double-oblique, contrast material-enhanced, double inversion-recovery, fast spin-echo magnetic resonance (MR) images were acquired through atheroma in the proximal internal carotid artery. Fibrocellular tissue within atheroma selectively enhanced 29% after administration of gadolinium-based contrast agent. Contrast enhancement helped discriminate fibrous cap from lipid core with a contrast-to-noise ratio as good as or better than that with T2-weighted MR images but With approximately twice the signal-to-noise ratio (postcontrast images, 36.6 +/- 3.6; T2-weighted images, 17.5 +/- 2.1; P < .001).
