Intracranial tumors after radiation therapy: role of 99mTc-tetrofosmin SPECT/CT with a hybrid camera.

Background: We evaluated the value of single-photon emission computed tomography/computed tomography (SPECT/CT) with a hybrid camera for (99m)Tc-tetrofosmin (TF) imaging of brain tumors and metastases after radiotherapy.

Methods: Forty (40) patients (27 with primary brain tumors and 13 with intracranial metastases) were examined 6 months after radiation therapy. SPECT images were first evaluated alone and then reinterpreted by adding the anatomic (CT) data.
