The arrival of MRI has resulted in large advancements in the noninvasive investigation of vascular malformations. Lesions and tender tissue depiction is vastly Increased particularly in comparison to CT. Non-ionizing radiation exposure is usually averted and 3D reconstruction is remarkable to CT. Distinction-Improved MRI and MRA are as a result the preferred imaging modalities for pre-technique diagnosis and interventional setting up venous malformation brain treatment singapore together with post-process analysis of your vascular malformation. Typical MRI has a hundred% sensitivity and 24% to 33% specificity in differentiating VMs from non-VMs (32). Dynamic distinction MR angiography boosts specificity to ninety five%.
