Recurrent cerebral gliomas in MRI and Iodine-123-alpha-methyl-tyrosine SPECT: the use of digitally fused images
open access
Abstract
MATERIAL AND METHODS: The findings of MR and SPECT imaging for 21 patients who had surgery for cerebral glioma were subject to assessment. Diagnosis was based on histopathology results (8 cases of anaplastic astrocytoma and 13 cases of multiform glioblastoma). The site and size of the contrast enhancement areas from MR was compared with the hot focus location from SPECT.
RESULTS: The study confirmed the feasibility of digital fusion of images yielded by SPECT and MR. The fused images reflect the non-homogeneity of the post-resection site of cerebral gliomas. Contrast enhancement areas only partially overlapped with the hot foci which, furthermore, were found to be substantially smaller.
CONCLUSIONS: The consistency of tumour locations detected with MR and SPECT was higher for tumours of the anaplastic astrocytoma type than for multiform glioblastomas (higher polymorphism of pathological changes).
