Planning scans done with CT scan brain, CT & MR angiography, then nidus volume and organ at risk (OARs) were contoured. Planning was done with multiplan planning system. Plan evaluated as per Flickenger model parameters of 12 Gy nomal brain vol & marginal dose. 7.5 mm and 10 mm cons ...
AVMs can form anywhere there are arteries and veins. Brain AVMs can occur on the surface (also called cortical), deep (in the thalamus, basal ganglia, or brainstem), and within the dura (the tough protective covering of the brain). ...

Purpose: Dosimetric study to evaluate impact of “beam” reduction in AVM radiosurgery on normal brain dose parameters and it’s clinical implications. Materials and Methods: Five small volume AVMs (nidus volume 0.31 - 1.94 cc) planned for single fractio
Age, hours between the initial CT scan and the injury (HCT1) and GCS at admission were observed as factors associated with PSH after logistic regression. Conclusions: In general, the use of glibenclamide to control plasma glucose after TBI had no significant effect on patient outcome at ...

Contrast-enhanced CT scan of brain revealed a markedly enhancing lesion in right frontal region (Fig. 78.1a, b). No mass effect was seen. MRI revealed a diffuse network of flow voids in parenchymal and subarachnoid space (Fig. 78.1c–f). The dilated vascular spaces seemed to be ...
A cerebral CT Scan showed a cerebellar hematoma. Digital subtraction angiography demonstrates a right paramedian supero-posterior infratentorial AVM located at the posterosuperior part of the right cerebellar hemisphere with a small compact nidus supplied by branches of the right ...
