Indium-113m perfusion study and the nonfunctioning thyroid nodule.
Indium-113m eluate has been used to study the perfusion of 12 patients with solitary thyroid nodules that appeared "cold" in the 131I and 99mTc image studies. Seven patients with colloid nodules showed no perfusion and the remaining five (three adenomas and two carcinomas) showed good perfusion with indium. Histologic confirmation was obtained in all cases. Indium-113m perfusion study may be useful in differentiating colloid nodules from either adenomas or carcinomas.
