Answer

Answer

Tl-201 has a higher avidity for low-grade NHL than does 67Ga. Therefore, it has a complementary role to 67Ga imaging in the diagnosis of low-grade NHL. However, the sensitivity of 201Tl for high-grade NHL is generally poor; in this case, 67Ga scintigraphy is the preferred imaging method.
