The capabilities of up-to-date SPECT in early post-operative diagnosis of intracerebral malignant tumors remnants
To determine the capabilities of SPECT in early postoperative diagnosis of tumor remnants in patients with malignant brain tumors, this method was used in 14 patients with suspected focal brains lesions together with other methods of neuroimaging (MRI and CT) before and after surgery. The diagnosis was verified histologically in all cases. The analysis of the findings showed that focal hyperfixation of the RP was noted in all tumors. In early post-operative period SPECT signs of pathological hyperfixation of the RP in the areas of the tumor were absent in 13 patients. Only in one case, postoperative emission tomograms (in contrast to CT) demonstrated an area of the RP hyperfixation, which corresponded to the remnants of the tumor tissue. The study showed that SPECT is effective in diagnosis of intracerebral tumors and can be used as an alternative method before and after the surgery. In some cases SPECT can be more informative than CT in diagnosis of malignant gliomas remnant tissue
