The advent of MRI has brought about enormous advancements inside the noninvasive investigation of vascular malformations. Lesions and smooth tissue depiction is vastly Improved in particular when compared to CT. Non-ionizing radiation publicity can also be avoided and 3D reconstruction is excellent to CT. Contrast-Increased MRI and MRA are hence the preferred imaging modalities for pre-process analysis and interventional preparing along with write-up-method analysis of your vascular malformation. Standard MRI has one hundred% sensitivity and 24% to 33% specificity in differentiating VMs from non-VMs (32). Dynamic contrast MR angiography raises specificity to 95%. The substantial spatial and temporal resolution of MRI permits an improved visualization in the lesion’s extent, In particular with the usage of newer blood pool distinction brokers for instance Ablavar® (gadofosveset trisodium, Lantheus Medical Imaging, North Billerica, MA, United states of america) that have an extended vascular half-lifestyle.
