Abstract Objective: To investigate the value of susceptibility weighted imaging (SWI) in the diagnosis of premature infants with intracranial hemorrhage (ICH). Methods: Sixty cases (26 male, 34 female) of premature infants with suspected ICH were consecutively collected in this study. All the patients were examined by 1.5T MR scanner with conventional MR (T1WI and T2WI), DWI and SWI sequences. SWI sequence was respectively compared with conventional MRI sequences and DWI in detecting intracranial hemorrhage, including the cerebral bleeding, intraventricular hemorrhage, subarachnoid hemorrhage (SAH) and subdural hemorrhage. Results: In sixty premature infants, thirty-nine cases with ICH were detected on SWI, twenty-eight on T1WI plus T2WI, thirty-three on DWI. Intraperenchymal hemorrhagic lesion was detected on SWI in 189 cases, on T1WI-T2WI and DWI in 92 and 111 cases, respectively. Twenty-five intracranial extracerebral (SAH and subclural) and intrarentricular hemorrhagic lesions were detected on SWI, 27 and 25 lesions were detected on T1WI-T2WI and DWI, respectively. For cerebral hemorrhage, there were significant difference between SWI and T1WI plus T2WI, as well as SWI and DWI (P<0.05). For extraxial hemorrhage and intraventricular hemorrhage, no statistical significance was found beween between SWI and T1WI plus T2WI, as well as SWI and DWI (P>0.05). Conclusion: SWI can detect more intracranial hemorrhage than conventional MRI sequence and DWI sequence, which is helpful for diagnosis of intracranial hemorrhage in premature infants.
