(a) Coronal 3D US view of a normal uterus; uterine wall thickness: distance between the line joining tubal ostia (interostial line) and a parallel line on the top of the fundus. (b) Coronal 3D US view of a partial septate uterus; 1, uterine wall thickness: distance between the line joining tubal ostia (interostial line) and a parallel line on the top of uterine fundus; 2, internal midline indentation: distance between the interostial line and a parallel line on the top of midline indentation. (c) Coronal 3D US view of a complete septate uterus: 1, uterine wall thickness: distance between the line joining tubal ostia (interostial line) and a parallel line on the top of uterine fundus; 2, internal midline indentation: distance between the interostial line and a parallel line on the top of midline indentation (the line reaches the internal cervical os). (d) Coronal 3D US view of a bicorporeal septate uterus: uterine wall thickness: distance between the interostial line and a parallel line joining the external outline of the uterine horns
