Dual isotope SPECT in the evaluation of recurrent brain tumor

Clin Nucl Med. 1992 Aug;17(8):663-4. doi: 10.1097/00003072-199208000-00012.


Dual isotope brain SPECT was performed in a patient with recurrent brain tumor (grade II astrocytoma). In this case, a good coregistration of brain perfusion and tumor images was obtained because Tc-99m HMPAO and the Tl-201 chloride imaging were done simultaneously using a Triad SPECT unit. This method might play an important clinical role in the evaluation of patients with recurrent brain tumors.
