Magnetization transfer (MT) techniques have been proposed as a method of increasing contrast in MR images. To evaluate the feasibility of MT imaging of the abdomen at 0.1 T and to assess the clinical utility of this technique, the authors studied tissue contrast with a gradient-echo pulse sequence and an MT sequence in four normal volunteers, and in 17 patients with known primary or secondary neoplasms of the liver. The MT technique increased contrast between the liver and other tissues such as spleen, skeletal muscle and subcutaneous fat. The technique also produced increased contrast between hepatic tumors and normal liver parenchyma in gradient-echo images.
磁化传递（MT）技术已被提出作为一种增加磁共振成像（MR）对比度的方法。为了评估在0.1 T场强下腹部MT成像的可行性并评估该技术的临床应用价值，作者采用梯度回波脉冲序列和MT序列，对4名正常志愿者以及17例已知原发性或继发性肝脏肿瘤的患者进行了组织对比度研究。MT技术增加了肝脏与其他组织（如脾脏、骨骼肌和皮下脂肪）之间的对比度。该技术还在梯度回波图像中增加了肝肿瘤与正常肝实质之间的对比度。
