Each operator was asked to obtain such an image five times from each of five patients. A total of 200 images from 40 patients were obtained and stored for subsequent analysis. All pregnancies were between 11 + 0 and 13 + 6 weeks of gestation. The angle between the falx cerebri and vertical axis (angle of deviation) was then measured by a single operator. A true midsagittal section was defined as an angle of deviation equal to 0\u00b0. The angle of deviation and the time taken to acquire each image were compared between FMF and non\u2010FMF groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The median angle of deviation for each operator ranged from 1.2\u00b0 to 3.4\u00b0. There was no significant difference in this angle between those who were FMF certified and those who were not (2.0\u00b0 vs. 2.2\u00b0, <jats:italic>P<\/jats:italic> = 0.463). The interquartile range of the angle of deviation was also similar between the FMF\u2010 and non\u2010FMF\u2010certified operators. Although the time taken for image acquisition was longer among the non\u2010FMF\u2010certified operators (median, 45.5s vs. 32.0s), this difference did not reach statistical significance (<jats:italic>P<\/jats:italic> = 0.107).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Live xPlane imaging can provide a tool to assist the acquisition of a true midsagittal plane and to determine how true a \u2018midsagittal\u2019 plane really is.
