[Roentgen image of the trachea in the supine position in substernal struma: a further possibility in avoiding radioiodine diagnosis].

It is recommended in substernal struma in the X-ray picture of the trachea prior to the X-ray picture in sitting position to make an X-ray picture in lying position, when the substernal part of the struma is not unequivocally to be seen in the 99mTc scintigram. Thus in many cases the discrepancy may be clarified and the radioiodine diagnostics be avoided.
