[Abstract] Objective: To evaluate the clinical value of susceptibility weighted imaging (SWI) in pediatric neurologic disorders.Materials and Methods: SWI was applied to 42 cases of pediatric neurologic disorders (12 cases of traumatic brain injury, 20 cases of hypoxic-ischemic encephalopathy, 1 case of cavernous angioma, 2 cases of arterio-venous malformation, 1 cases of Sturge-Weber sydrome, 6 cases of neoplasms), and compared with conventional sequences (T1, T2 FLAIR, T2 FSE, DWI), and some of them with T1 postcontrast, MR angiography, MR spectroscopy.Results: SWI showed more lesions in diffusion axonal injury and subarachnoid hemorrhage. Due to the image artifacts, SWI was not as good as T1 FLAIR to detected Subdural hemorrhage. SWI showed more hemorrhage lesions in HIE than other sequences. Certain types of vascular malformations with slow flow had been shown to be better visualized with SWI, including cavernous angioma, arterio-venous malformation and sturge-weber syndrome. SWI increased the visibility of tumors and was helpful for depicting hemorrhage and increased vascularity in the neoplasms, which may reflect tumor grade.Conclusion SWI was superior to the conventional sequences for visualizing hemorrhage and vascular structure. SWI can provide useful additional information in the evaluation of various pediatric neurologic conditions.
