Different structural as well as functional imaging techniques are becoming increasingly important in the investigation of patients suffering from an ischemic stroke. Available imaging procedures usually provide complementary data, but the images can not easily be compared due to differences in patient positioning, angulation, and slice thickness. We studied the value of spatial integration of images from different modalities in a patient with an ischemic stroke and used skin markers to integrate the obtained information. Computed tomography (CT), magnetic resonance imaging (MRI), 99mTcHMPAO-single photon emission computed tomography (SPECT) and magnetic resonance spectroscopic imaging (MRSI) were performed in a patient, presenting with a right sided hemiparesis caused by an ischemic stroke. Combination of MRI with CT demonstrated that the infarction visible on CT and MRI corresponded in size and volume. Furthermore, structural and functional images could readily be integrated, thus allowing us to obtain accurate information in this stroke patient. Different imaging modalities provide complementary information in the acute phase of cerebral infarction and multimodality matching can be of great value for improvement of our understanding of the pathophysiology and course of ischemic stroke.
不同的结构和功能成像技术在缺血性中风患者的研究中变得越来越重要。现有的成像程序通常提供互补的数据，但由于患者体位、角度和切片厚度的差异，图像不容易进行比较。我们研究了在一名缺血性中风患者中不同模态图像空间整合的价值，并使用皮肤标记物来整合所获得的信息。对一名因缺血性中风导致右侧偏瘫的患者进行了计算机断层扫描（CT）、磁共振成像（MRI）、99mTcHMPAO单光子发射计算机断层扫描（SPECT）和磁共振波谱成像（MRSI）。MRI与CT的结合表明，CT和MRI上可见的梗死灶在大小和体积上相对应。此外，结构和功能图像可以很容易地整合，从而使我们能够在这名中风患者中获得准确的信息。不同的成像模态在脑梗死急性期提供互补信息，多模态匹配对于提高我们对缺血性中风病理生理学和病程的理解具有重要价值。
