Radiation necrosis

Diagnosing radiation necrosis versus tumor recurrence is also a useful and accurate application of indacranial MR specdoscopy (Schlemmer et al., 2001 Nelson, 2003). Radiation necrosis will have large Lip and Lac peaks without elevated Cho whereas tumor would have elevated Cho. MRSI is particularly useful for distinguishing recurrent tumor versus radiation necrosis given its ability to spatially sample multiple areas of a lesion (Chernov et al., 2005). [Pg.757]

Thallium-201 SPECT and fluoro-deoxyglucose (FDG) PET are both used to help differentiate residual brain tumor and brain tumor recurrence from radiation necrosis. Thallium-201 SPECT has been found to be just as good or even better for tumor detection than FDG PET (Kahn et al., 1994 Maria et al., 1998 Stokkel et al., 1999). Thallium-201 SPECT can also be utilized to help differentiate lymphoma from toxoplasmosis which is an important question in immunocompromised... [Pg.758]

Eighteen out of 22 patients underwent mTHPC-mediated intraoperative photodynamic diagnosis and fluorescence guided resection. Two were false negative (selectivity 89%) because of too low a sensitivity of the primary instrumentation and three were false positive due to radiation necrosis and inflammatory reactions (specificity 84%). Additional spectroscopy applied in the last cases increased significantly the sensitivity of our system. Postoperative MR studies within 48 h revealed complete tumor removal in 10 cases, unintentional residual tumor in three cases, and in five patients tumor had to be left because of invasion in functional structures [30]. In no cases was normal brain resected (Table 4). [Pg.230]
