There was a recent publication that there is interhemispheric asymmetry on the anterior margin of the Meyer's loop by means of perimetry. Only few studies have compared this by imaging. We measured the distance of the anterior margin of the Meyer's loop from the temporal pole (DTT) in both hemishperes, which appear as high SI distinguishable from adjacent structures on MPRAGE at a certain time window during myelination, in 47 infants. The measurements were significantly shorter in the left (left :22.52.7 mm, right: 24.02.4 mm). This is the first study to our knowledge to backup that there is interhemishperic asymmetry of DTT image wise, and will encourage validation by other investigators.
