Evaluation of cold areas on the thyroid scan with 67Ga-citrate.
Cold areas on 131I or 99mTc thyroid scans were re-evaluated using 67Ga-citrate in 134 patients. In 62 patients surgical specimens were obtained for histologic studies. Of 46 benign lesions, all had negative 67Ga scans, and 67Ga scans in 5 of the 16 lesions judged to be malignant were positive. It was thought that the sensitivity of the method did not warrant its use for routine screening in evaluations of malignancy of thyroid nodules.
