[Clinical value of 99mTc-MIBI imaging, 131I whole body scan and HTG determination for the follow-up of patients with differentiated thyroid carcinoma after 131I therapy].
The purpose of this study was to make a comparative evaluation of 99mTc-MIBI imaging, 131I whole body scan and HTG determination in use for the follow-up of patients with differentiated thyroid carcinoma (DTC) after 131I therapy. Fifty-three patients with DTC had undergone surgical treatment and 131I ablation. Clinical examinations showed that 22 of them had metastases or recurrences. In the follow-up of all the patients, the HTG determination, the 99mTc-MIBI imaging and the 131I-WBS were performed in sequence after the discontinuance of the administration of thyroxin for 4-6 weeks. The results showed that the sensitivity, specificity and accuracy of 99mTc-MIBI imaging were 86.36%, 87.10% and 86.79% respectively; those for HTG were 68.18%, 100% and 86.79% and those for 131I-WBS were 63.64%, 100% and 84.91% respectively. The total sensitivity of the three examinations was 100%; the total specificity and total accuracy were 87.10% and 92.45% respectively. The data of this study suggest that 99mTc-MIBI imaging is a highly sensitive method and the combined use of the three examinations can improve the sensitivity and accuracy of diagnosis for patients with DTC.
