However, the measurement of the FMF angle was artificially increased when in the mid\u2010sagittal plane the angle was 40\u201399\u00b0 and 150\u2013199\u00b0.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Successful assessment of the FMF angle by 3D ultrasound is dependent on the plane and angle of the volume acquisition.
