Brain SPECT by 99mTc-Tetrofosmin for the Differentiation of Tumor Recurrence from Radiation Injury

Comparison of brain SPECT with 99mTc-MIBI and CT-scan in discriminating of radiation necrosis and brain tumor recurrence [Persian]

Introduction: 99mTc-MIBI has been proposed for use as an imaging agent for various tumors, including breast cancer, lung cancer, lymphomas, melanomas and brain neoplastic lesions. Brain tumors are very common and radiotherapy being major part of treatment following surgery. After radiotherapy, deteriorating clinical status can be due to either radiation necrosis or recurrent tumor. Comput...

Diffusion-weighted imaging of radiation-induced brain injury for differentiation from tumor recurrence.

BACKGROUND AND PURPOSE Differentiation between tumor recurrence and treatment-related brain injury is often difficult with conventional MRI. We hypothesized that the diffusion-weighted imaging (DWI) could help differentiate these 2 conditions, because water diffusion may be greater for necrotic tissues in the treatment-related brain injury than for tumor tissues in recurrence. Our aim was to an...

PET in differentiation of recurrent brain tumor from radiation injury.

The annual incidence of primary intracranial tumors is 7 to 19 cases per 100,000 people. The general approach to the treatment of brain neoplasms is surgical resection of solitary lesions or limited disease, followed by radiation therapy with or without chemotherapy. Multiple metastatic lesions are usually treated with whole-brain radiation. Radiation injury occurs in 5% to 37% of cases and can...
