Abstract:
PURPOSE: This study was designed to evaluate whether diffusion-weighted imaging (DWI) showed characteristic features in patients with an intracerebral hemorrhage (ICH), as well as a cerebral infarction, and whether the volume of hemorrhage was measured accurately on the DWI. MATERIALS AND METHOD: Patients with an ICH who underwent DWI and computed tomography (CT) were enrolled in this study. The DWI findings were categorized as follows: type A (lesions with a mixed-signal intense core), type B (lesions with a low-signal intense core), and type C (otherlesions). The time interval between symptom onset and DWI was compared among types of DWI findings. We compared the volumes of the hematomas between CT and DWI. RESULTS: Thirty-seven patients were classified as type A (27 cases), type B (9), and type C (1). The average time interval was significantly different between type A and type B (4.97 vs 41.89 hrs). The differences between the measured mean volumes of the hemorrhages between CT and DWI were not statistically different (12.7 vs 12.4 ml) CONCLUSION: This study suggested that DWI could differentiate ICH from ischemic stroke and could accurately measure the hemorrhagic volume, as well. Thus, it can be used as a primary diagnostic tool of stroke in the emergency department.
