BACKGROUND: Intraventricular hemorrhage (IVH) may be difficult to detect
especially when in small amounts and may affect outcomes. The objective of this
study was to compare the sensitivity of magnetic resonance imaging (MRI) vs
computed tomography (CT) for the identification and quantification of IVH.
METHODS: Patients with primary intracerebral hemorrhage were enrolled into a
prospective registry between December 2006 and June 2013. Diagnostic and
surveillance neuroimaging studies were analyzed for the presence of IVH and
quantified by Graeb score. In subjects who developed IVH and underwent both MRI
and CT, each MRI was paired with the CT scan done at the closest time point, and
Graeb scores were compared with the Wilcoxon signed rank test for related
samples. RESULTS: There were 289 subjects in the cohort with IVH found in 171.
Sixty-eight pairs of MRI and CT were available for comparison. CT failed to
detect IVH in 3% of cases, whereas MRI was 100% sensitive. MRI and CT yielded
equal Graeb scores in 72% of the pairs, and MRI Graeb score was higher in 24% (P
= .007). CONCLUSIONS: MRI identifies small volumes of IVH in cases not detected
by CT and yields higher estimates of intraventricular blood volume. These data
indicate that consideration of technical differences is needed when comparing
images from the 2 modalities in the evaluation for IVH.
