Fig 3. Therapy outcome based on TT4 values obtained in both groups 6 months after radioiodine treatment. The normal range of TT4 expressed in nmol/l is 15.5-51.6. Below normal limits was found in 54% (iohexol group) and 55% in the control group. Euthyroidism was seen in respectively 31% (iohexol group) and 39% and higher than normal TT4 values were found in 15% of the iohexol group and 6% in the radioiodine treatment only group.
