Purpose Vascular malformations include a broad range of diverse lesions that can affect every region of the body and can lead to serious illness in both adults and children. They usually grow proportionally with the age and show no regression. Magnetic resonance (MR) imaging in combination with MR angiography performed with intravenous administration of gadolinium-based contrast has an important role in evaluating the extent of lesions, particularly deeper lesions, and their relationship to adjacent structures According to the preponderant vascular channels, vascular malformations are...
Read more Methods and materials We use a torso phased-array coil for imaging the chest, abdomen, and pelvis and specialized peripheral phased-array coils for imaging the extremities. Examination protocols should include 1.SE or fast SE T1-weighted imaging for basic anatomic evaluation2.Fat-suppressed fast SE T2- weighted3.Short τ inversion-recovery (STIR) imaging to assess extension of the lesion.4.GRE T2*-weighted images can be used in some cases to demonstrate calcification or hemosiderin, as well as high-flow vessels.5.Contrast material–enhanced MR angiography, performed with a 3D T1-weighted fast gradientecho (GRE) sequence with intravenous...
Read more Results Out of 30 patients (16 female), the mean age at presentation was 23 years (range: 20-40 years).The most common clinical findings were swelling (79%), skin discolouration. Contrast-enhanced MRI was done in all cases.
Read more Conclusion MR imaging is a crucial tool in diagnosing and evaluating slow-flow AVMs. It provides valuable insightsinto the vascular structure, flow dynamics, and potential complications. Early detection through advanced MR techniques can guide timely interventionand improve patient outcomes. Further dynamic  study may benefit and replace need of digital substraction angiography.
