甲状腺髓样癌对^(99m)Tc(V)-DMSA的摄取

Uptake of ^(99m)Tc(V) dimercaptosuccmic acid in the medullary thyroid carcinoma

本文报道应用自制^(99m)TC(V)-DMSA对15例临床诊断为甲状腺肿瘤患者的显像研究,结合病理探讨了临床应用价值。2例甲状腺髓样癌患者呈强阳性,病灶放射性分布类似CT所见,而其余甲状腺良恶性病变几乎均阴性。结果表明:^(99)Tc(V)-DMSA对甲状腺髓样癌的诊断、病灶定位定性、治疗随访等有较大临床价值。

Fifteen patients with clinical diagnosed thyroid tumor were examined with 99mTc(V) -DMSA and the results were compared with pathologic findings. The lesions of 2 patients with medullary thyroid carcinoma had strong positive uptake and the pattern of radioactive distribution were similar to that of CT scan, Uptake of the other benign and malignant diseases of thyroid were almost negative. The results indicated that the use of 99mTc(V) DMSA would be great clinical value for the diagnosis, localization and follow-up of medullary thyroid carcinoma.
