Susceptibility weighted imaging (SWI) is a new MRI technique that can identify calcification by using phase images. We present a single case with a partially calcified oligodendroglioma, multiple calcified cysticercosis lesions, and multiple physiologic calcifications in the same patient. SWI phase images and computed tomography (CT) images are compared. SWI phase images showed the same calcified lesions as shown on CT and sometimes some new calcifications. Our conclusion is that SWI filtered phase images can identify calcifications as well as CT in this case.
磁敏感加权成像(SWI)是一种新的磁共振成像技术,它可以通过相位图像识别钙化。我们报告一例同一患者存在部分钙化的少突胶质细胞瘤、多发钙化的囊尾蚴病病灶以及多处生理性钙化的病例。对SWI相位图像和计算机断层扫描(CT)图像进行了比较。SWI相位图像显示出与CT相同的钙化病灶,有时还能显示出一些新的钙化灶。我们的结论是,在该病例中,SWI滤波后的相位图像识别钙化的能力与CT相当。
