Systematic review of the diagnostic accuracy of 201Tl single photon emission computed tomography in the detection of recurrent glioma.

Objective: To determine the diagnostic accuracy of 201Tl SPECT in the detection of tumour recurrence in patients with previous radiotherapy for supratentorial glioma.

Methods: The databases of PubMed and Embase were searched for relevant studies. Two reviewers independently selected and extracted data on study characteristics, quality and accuracy of studies.
