The advent of MRI has led to substantial advancements from the noninvasive investigation of vascular malformations. Lesions and comfortable tissue depiction is vastly Improved in particular when compared to CT. Non-ionizing radiation publicity is likewise averted and 3D reconstruction is exceptional to CT. Distinction-Improved MRI vascular malformation and MRA are as a result the preferred imaging modalities for pre-course of action prognosis and interventional preparing as well venous malformation brain treatment singapore as write-up-technique evaluation from the vascular malformation. Common MRI has one hundred% sensitivity and 24% to 33% specificity in differentiating VMs from non-VMs (32). Dynamic contrast MR angiography boosts specificity to ninety five%.
