Background •Accurate measurements of fetal thymus are critical for evaluation of fetal chromosome abnormality (Deletion 22q11) and intrauterine infection. •The thymus is extremely irregular in three-vessel tracheal (3VT) view for its close proximity to the blood vessels. •We found the transverse section of fetal thymus on the innominate vein (INV) slightly above the 3VT section has linear back boundary and more regular shape which is easier to measurement than on the 3VT view.
