Intracranial aneurysms are rare in children. The utility, yield, and effectiveness of screening for aneurysms in children and young adults with a predisposing history for aneurysms or a family history of aneurysms is not known. The purpose of this study is to assess the prevalence of positive imaging studies performed for screening of intracranial aneurysms in children with familial history of intracranial aneurysms, and determine the utility and yield of these studies.

The purpose of this educational presentation is to delve into the physics of Microvascular Flow Imaging (MVFi) and showcase its significance in the imaging of pediatric vascular anomalies. MVFi complements grayscale and traditional color or power Doppler imaging of vascular malformations.
MVFi is an advanced Doppler ultrasound technique that excels in detecting slow blood flow in smaller vessels and capillaries without the use of a contrast agent. Different vendors utilize proprietary MVFi algorithms to isolate the slow flow signal from tissue artifacts and enhance spatial resolution. However, MVFi algorithms are susceptible to motion and flash artifacts, which can be challenging in young children. Nevertheless, in the appropriate setting, MVFi enables improved delineation of slow-flow lesions through the detection of intravascular slow flow, which may be located in the lesion or in the surrounding tissues.
MVFi can play a vital role in monitoring residual or recurrent disease following intervention. In this work, we will explore the physics through case presentations to illustrate the combined use of MVFi with grayscale and conventional Power Doppler in diagnosing and managing pediatric vascular anomalies with slow flow.
