Methods and materials
A retrospective study,
from January 2006 to November 2018,
of 15 fetuses studied by MRI because of suspected cerebral pathology on cerebral US,
in which MRI revealed ICH.
The characteristics of our study population are summarized in Table 1.
Two expert radiologists in fetal imaging reviewed the clinical histories and US imaging studies to correlate them with MRI and postnatal imaging findings or necropsy,
when available.
The following classification system was used (Currently used in neonates to classify fetal ICH by US) [6,
7]:
- IVH grade I: Limited to the subependymal matrix.
- IVH grade II: Less than 50% of the lateral ventricles filled with blood.
- IVH grade III: More than 50% of the lateral ventricles filled with blood and ventriculomegaly.
- IVH grade IV: Presence of periventricular hemorrhagic venous infarction.
Tables 2,
3,
4 present the data of the fetuses studied numbered from 1 to 15 with the respective gestational age in weeks at the time MRI was performed.
They also summarize and compare the different US and MRI findings.
Figure numbers are located in the last column.
