By combining filtered phase and magnitude information to create a novel and intrinsic source of contrast, susceptibility-weighted imaging (SWI) has shown great promise in clinical angiography and venography. SWI has contributed to new insights into traumatic brain injury, the role of calcification in atherosclerosis, and the possible relationship between blood settling and deep venous thrombosis. A further contribution from SWI to deep venous thrombosis research (and also stroke) involves its application to the noninvasive measurement of oxygen saturation in the brain and in other tissues. Altogether, SWI offers manifold and diverse avenues for further research using angiographic and venographic techniques.
通过结合滤波后的相位和幅度信息来创建一种新颖且内在的对比度来源，磁敏感加权成像（SWI）在临床血管造影和静脉造影中显示出了巨大的前景。SWI有助于对创伤性脑损伤、钙化在动脉粥样硬化中的作用以及血液沉积与深静脉血栓形成之间的可能关系有新的认识。SWI对深静脉血栓形成研究（以及中风研究）的另一贡献涉及将其应用于大脑和其他组织中氧饱和度的无创测量。总之，SWI为使用血管造影和静脉造影技术的进一步研究提供了多种不同的途径。
