Feasibility and precision of transcutaneous very-high resolution ultrasound for quantification of arterial structures in human neonates - Comparison with conventional high resolution vascular ultrasound imaging

VHRU is feasible, accurate and precise in the assessment of superficial proximal conduit arteries but unable to assess the abdominal aorta in human neonates HRU-derived neonatal conduit arterial wall layer thicknesses are below the ultrasound axial resolution.
