computed tomography (SPECT) studies in distinguishing the histological malignancy of …

In order to reassess the value of quantitative thallium-201 brain SPECT in the differentiation
of miscellaneous brain tumors, we studied a total of 89 patients—35 pre-operative patients …

BACKGROUND: Thallium-201 (Tl-201) is the most commonly used tracer for functional
imaging of recurrent brain tumours. However, the physical properties of Tl-201 are not …

The aims of this study were to assess the utility of 201 Tl single photon emission tomography
(SPET) in the differential diagnosis of brain tumours and to elucidate the relationship …

Thallium-201 is clinically used for the assessment of primary and recurrent brain tumors. The
biologic properties of 201TIthat allow it to accumulate within the tumor cells render …
