Objectives: To distinguish between neoplastic and non-neoplastic lesions showing ring enhancement or ring like lesions in the brain in CT or MRI with the help of correlative Nuclear imaging. Material and Methods: Twenty seven patients with various ring enhancing lesions in the brain detected in CT and/ or MRI were correlated with cerebral first pass study, Planar and SPECT imaging using different radiotracers like 99m Tc-HMPAO. TI-201, 99m Tc-DTPA/GHA, 99m mTc-MIBI or Tetrofosmin Results: Nuclear scanning was helpful in distinguishing between neoplastic and non-neoplastic conditions in 42 percent of cases in this study where C T or MRI were doubtful. Conclusion: Nuclear imaging coupled with CT or MRI provides a fairly accurate diagnosis in differentiating neoplastic conditions from non-neoplastic conditions without any MR Spectroscopic or Sterotactic biopsy technique applied on the patients.
