Clinical evaluation of tumor imaging with 201 TI chloride.
201TI was used as an imaging agent in 173 malignant tumors and 76 benign lesions. The sensitivity, specificity, and accuracy were 0.64, 0.61, and 0.63, respectively. Sensitivity was good in thyroid cancer (0.91) and fair in primary lung cancer (0.70) and primary liver cancer (0.71). Compared with 67Ga, 201TI appears to have a higher sensitivity in thyroid cancer and nearly the same sensitivity in primary lung cancer. 201TI might be useful in distinguishing cold thyroid nodules and in differentiating primary liver cancer from metastases.
