Determination of reference values for normal cranial morphology by using mid-sagittal vector analysis in japanese children

Mid-Sagittal Vector Analysis (MSVA) is a method of measuring the distance from a defined central point on the skull surface in the entire mid-sagittal plane and provides a clear description of the lateral view of the skull. We used a series of images of normal skulls of Japanese children to determine normal MSVA values.For this cross-sectional study, we first constructed a database of head CT and MRI images of children aged 0–6 years (41.5±24.9 month (mean±SD)) who showed no abnormality of cranial development and growth at the time of imaging.
