使用相衬成像（质子化学位移成像，质子光谱）和使用常规T1和T2加权磁共振（MR）成像序列获得的数据进行比较，评价了各种人类肿瘤的肝脏外，具有广泛的组织学类型的显着性。在所有的病例中，使用相衬技术时肿瘤最明显。在两种情况下，肿瘤只能通过这种方法来识别，而不能通过任何常规MR脉冲序列来检测。当评价肿瘤的存在或范围时，建议使用相位对比成像作为标准MR序列的辅助，无论其解剖位置或组织学类型如何。
The conspicuity of a variety of human tumors outside the liver, with a broad spectrum of histologic types, was evaluated using phase-contrast imaging (proton chemical shift imaging, proton spectroscopy) and the results compared with the data obtained using routine T1- and T2-weighted magnetic resonance (MR) imaging sequences. In all cases, tumors were most conspicuous using the phase-contrast technique. In two instances, the tumors could be discerned only by this method, being undetectable by any routine MR pulse sequence. The use of phase-contrast imaging is recommended as an adjunct to standard MR sequences when evaluating for either the presence or extent of a tumor, regardless of its anatomic location or histologic type.
