Transcranial Ultrasound Localization Microscopy in Moya Moya patients using a clinical ultrasound system
Résumé
microbubbles US ultrasound ULM ultrasound localization microscopy CEUS contrast-enhanced ultrasound TOF MRI time of flight magnetic resonance imaging LSA lenticulostriate arteries MCA middle cerebral artery ACA anterior cerebral artery PCA posterior cerebral artery Key Results: -2D low-frame rate Ultrasound Localization Microscopy (ULM) allows visualization of perforating arteries, i.e. diameter of 0.8 ± 0.3 mm. -ULM described vessels that were not visible in conventional imaging techniques, i.e. TOF MRI and color Doppler. -ULM reconstruction and quantification of the perforating arteries enabled the pathological group (Moya Moya) to be distinguished from control subjects.
