Abstract

IntroductionThis study aims to evaluate the capability of magnetic resonance imaging MRI susceptibility weighted images SWI in depicting retinal hemorrhages RH in abusive head trauma AHT compared to the gold standard dilated fundus exam DFE.

MethodsThis is a retrospective, single institution, observational study on 28 patients with suspected AHT, who had a DFE and also underwent brain MRI-SWI as part of routine diagnostic protocol. Main outcome measures involved evaluation of patients to determine whether the RH could be identified on standard and high-resolution SWI sequences.

ResultsOf the 21 subjects with RH on DFE, 13 62 % were identified by using a standard SWI sequence performed as part of brain MRI protocols. Of the 15 patients who also underwent an orbits SWI protocol, 12 80 % were positive for RH. None of the seven patients without RH on of DFE had RH on either standard or high-resolution SWI. Compared with DFE, the MRI standard protocol showed a sensitivity of 75 % which increased to 83 % for the orbits SWI protocol.

ConclusionsOur study suggests the usefulness of a tailored high-resolution orbits protocol to detect RH in AHT.
