Results at conventional magnetic resonance (MR) angiography were compared with results at MR imaging with a sequence combining optimized magnetization transfer (MT) saturation and tilted optimized nonsaturating excitation (TONE). Forty images were obtained of five healthy volunteers and five patients with known intracranial vascular abnormalities (four men and six women, aged 22-72 years). Four blinded readers found improved vessel penetration, enhanced vessel-to-background contrast, the better vessel detail in the MT saturation-TONE images than in the conventional three-dimensional time-of-flight MR angiograms.
将传统磁共振（MR）血管造影的结果与采用优化磁化传递（MT）饱和与倾斜优化非饱和激发（TONE）相结合序列的MR成像结果进行比较。对5名健康志愿者和5名已知颅内血管异常的患者（4名男性和6名女性，年龄22 - 72岁）进行了40次成像。4名不知情的阅片者发现，与传统三维时间飞跃MR血管造影相比，MT饱和 - TONE图像的血管穿透性更好、血管与背景的对比度更高、血管细节更清晰。
