Figure 4From: Magnetic resonance spectroscopic study of radiogenic changes after radiosurgery of cerebral arteriovenous malformations with implications for the differential diagnosis of radionecrosisSame patient as Figure 1. Additional follow-up post-treatment examinations reveal constant hyperintensities in FLAIR (a-c) and contrast-enhanced MRI (d-f [f = axial MPR]) six weeks (a,d), three more months (b,e), and 20 months (c,f) after initial post-treatment MRI as shown in Figure 2 indicating non-malignant disease.Back to article page
