Everything You Always Wanted to Know About Radiosurgery of AVM (But Were Afraid to Ask)
Stereotactic radiosurgery (SRS) is an effective management option of intracranial AVM. It is particularly indicated for deep-seated or critically-located lesions. Successful treatment results in obliteration of the nidus within 1-3 years (so-called “latency period”) due to gradual thickening of the vessel wall. In small AVM (® is used. In general, it seems that for Spetzler-Martin […]
Differentiation of Radiation-Induced Changes and Tumor Progression After Intracranial Radiosurgery
A number of intracranial tumors demonstrate some degree of enlargement after stereotactic radiosurgery. It necessitates differentiation of their regrowth and various treatment-related effects. The diagnosis is frequently complicated by histopathological heterogeneity of the lesion with coexistent viable neoplasm and radiation-induced tissue changes. Several neuroimaging modalities, namely structural MRI, DWI, DTI, perfusion CT and MRI, single-voxel […]
